Hi John

While not an answer to your question, you might like this post "Why I don?t use spork" as an alternative perspective. Kevin's argument is that "Spork solves the wrong problem".

After Nikolay taught me that you can have multiple RSpec guards in a Guardfile, having a Rails-independent lib with continuous development testing seems pretty feasible. (I haven't tried it, but I'm tangentially involved in a project where we may be able to give it a go.)

BTW there's also the Destroy All Software screencast "Fast Tests With and Without Rails"[2] which I found yesterday, sounds to describe the same idea. I haven't watched it yet though (maybe somebody else here has?) - $9 is a lot of money to spend on a whim you know :)

HTH in some way

Cheers
Ash

Hi,

After upgrading to rails 3.1 and rspec-rails 2.6.1 I get the following 
deprecation warning, however as far as I can tell I am not defining any 
examples before it is called.

I am using the default spec_helper generated with rails g rspec:install so 
why this warning?

Thanks

*****************************************************************
DEPRECATION WARNING: you are using deprecated behaviour that will
be removed from RSpec 3.

You have set some configuration options after an example group has
already been defined.  In RSpec 3, this will not be allowed.  All
configuration should happen before the first example group is
defined.  The configuration is happening at:

 .../spec/spec_helper.rb:10

Yes I needed to run the guard with bundle exec.

I didn't think of looking in closed bugs :) I guess the fix has not made 
into the current release.

I think this gives me enough clues as to what I need to do to fix it though,

thanks

You only need shoulda-matchers if you're using rspec.

When there is no have_xxx method defined, rspec-expectations implements method_missing such that it assumes you want to send the object the has_xxx? predicate. What your experiencing suggests that there is no have_indices method. Looking at http://rdoc.info/github/thoughtbot/shoulda-matchers/master/Shoulda/Matchers/ActiveRecord, I see a singular have_db_index matcher, but I don't see a pluralized one, so perhaps this method doesn't exist. If it does, then something is wrong with your configuration, as it is not being made available.

HTH,
David

Thanks,
I updated spec with correct statements

  it { should have_db_index([:user, :currency, :tradable]) }
----------
and my db (dev and test) has the indexes

Indexes:
Action	Keyname	Type	Unique	Packed	Field	Cardinality	Collation	Null
Comment
Edit 	Drop 	PRIMARY	BTREE	Yes	No	id	0	A
Edit 	Drop 	index_balances_on_currency_id	BTREE	No	No	currency_id	0	A
YES
Edit 	Drop 	index_balances_on_tradable_id	BTREE	No	No	tradable_id	0	A
YES
Edit 	Drop 	index_balances_on_user_id	BTREE	No	No	user_id	0

but I get an error running rspec
  2) Balance shoulda validations
     Failure/Error: it { should
have_db_index([:user, :currency, :tradable]) }
       Expected Balance to have a  index on columns user and currency
and tradable ()

The indexes are on xxx_id. Try { should have_db_index([:user_id, :currency_id, :tradable_id]) }

My guess is that it is checking for an compound index on all of those
fields.  Try specifying them individually and not in an array.

@Katrina - actually it does contain an example ("it") in the nested group ("describe"). There's just no example in the outer group, but that's a red herring vis a vis this issue.

@Nick - the backtrace tells you the whole story. You just have to look at it.

The problem is that caused when rspec-mocks is asking the incoming Catalog object if it is == to the expected @catalog (as declared in the 'with' clause). rspec-mocks has a feature that allows you to check against a matcher object (i.e. foo.should_receive(:bar).with(hash_including(:a => 'b'))). This is implemented in https://github.com/rspec/rspec-mocks/blob/v2.5.0/lib/rspec/mocks/argument_expectation.rb. rspec-mocks incorrectly thinks the @catalog is a matcher because it responds to :matches? and :description (see https://github.com/rspec/rspec-mocks/blob/v2.5.0/lib/rspec/mocks/argument_expectation.rb#L29), and therefore wraps it in a MatcherMatcher (https://github.com/rspec/rspec-mocks/blob/v2.5.0/lib/rspec/mocks/argument_matchers.rb#L101-109), which asks the @catalog if it matches? the incoming catalog, which mixes in the Mongoid::Matchers module (https://github.com/mongoid/mongoid/blob/c4675a987925a831dc93ab5c525c99dedf46c841/lib/mongoid/matchers.rb#L19-30). That's how we get to `each_pair` on the Catalog.

So the bug is that rspec's definition of what a matcher is is too loose in this case. The problem is that this is RSpec's API for argument matching. If we were to make it more strict now, we'd break unknown numbers of existing specs.

To get around this, you can do this:

SpreadsheetImporter::Products.stub(:new) do |catalog, excel|
  catalog.should eq(@catalog)
  excel.should eq(@excel)
  @products_importer
end

This has the same effect as what you are trying to do (stub SpreadsheetImporter::Products returning @products_importer, and verify the arguments are the right ones).

HTH,
David

hello,
I would like to assert that an attribute of a model has value among
those in an array. How would I do it in rspec?

Something like this...

describe OptionType do
  context "shoulda validations" do
    it { assert_contains :type, ['Type1', 'Type1']}
  end
end

Yes. Thank you. I changed the code to list indices one at a time and
it worked.

    it { should have_db_index(:currency_id) }
    it { should have_db_index(:user_id) }

Hey Slavix. How about this:

it 'has a valid "attribute_x" value' do
  valid_values = %w(some values here)
  valid_values.should include subject.attribute_x
end

Thanks. I wanted to test it as part of model validation like

    it { should validate_presence_of(:some_attribute).among(['value1',
'value2']) }
    it { should validate_that(:some_attribute) >= 0 }

this seems to be the way to do it.

    it
{ should_validate_numericality_of :amount, :greater_than_or_equal_to
=> 0 }
    it { should_validate_inclusion_of :gender, :in => %w( m f )

Hello,
I have this in my spec
    it { should
validate_numericality_of(:amount).greater_than_or_equal_to(0) }

but I get error:

Failure/Error: it { should
validate_numericality_of(:amount).greater_than_or_equal_to(0) }
     NoMethodError:
       undefined method `greater_than_or_equal_to' for

this page
http://remarkable.rubyforge.org/activerecord/classes/Remarkable/ActiveRecord/Matchers.html
has method
  it { should validate_numericality_of(:age).only_integer }

and :less_than_or_equal_to is a valid option..

I am confused. How do I spec this? thanks.

I have a basic user class and doing rspec validations.  When I do a factory 
create to produce validations it blows up before I can get to the second 
line to check for errors.  Ideas how to get this to perform like AR 
Validations?

MongoMapper::DocumentNotValid:
       Validation failed: Password can't be blank, Email can't be blank, 
Password digest can't be blank

class User
  include MongoMapper::Document
  include ActiveModel::SecurePassword

  key :password_digest, String
  key :password, String, :required => true
  key :email, String, :required => true
      
  has_secure_password
end

it "should not authenticate with incorrect password" do
      user = Factory(:user, :email=> '', :password => '').should 
have(2).errors
      #user.should have(2).errors #_on(:name)

Hey Chris. Could you be more specific than "it blows up"? If there's a stack 
trace, that'd be helpful.

Sorry,  it fails validation which it should but it errors out in the cli as
opposed to going along and checking, it does not get past the inital factory
new line:

Failure/Error: user = Factory(:user, :email=> '', :password => '')
     MongoMapper::DocumentNotValid:
       Validation failed: Password can't be blank, Email can't be blank,
Password digest can't be blank

This is not why you're having trouble, but rspec-1.1.9 is nearly three years old: http://rubygems.org/gems/rspec/versions/1.1.9.

See http://relishapp.com/rspec and http://rubydoc.info/gems/rspec/frames for the latest.

Cheers,
David

The describe() method creates an example group, and the it() method creates an example. This ^^ line needs to be in an example:

describe Bitcoin do
  it "defaults to BTC for char_code" do
    Bitcoin.instance.char_code.should eq('BTC')
  end
end

re: whether to use eq, eql, or equal, see http://relishapp.com/rspec/rspec-expectations/docs/built-in-matchers/equality-matchers

David

Is there a way to run an `around` block once for every spec *file*
(not spec)? (I want to measure which files take the longest amount of
time, count the number of specs in each file, and then report the
average spec running time for that file.)

Test the behaviour, not the implementation. You could look at using a shared example group if you want to specify that the subclass shared behaviour with the superclass.

Message-ID: <CABTrMvU1cHdMJZFc24MXSwEMHmNV85Nhx4a-sTWOsEPkaaGEdQ@mail.gmail.com>

Is there a way to warn but not fail if a particular method wasn't
called? That is, I'm looking for something that's halfway between
obj.stub(...) and obj.should_receive(...). I'm trying to do something
like this:

shared_context "with a stubbed geocoder" do
  before(:each) do
    @geocoding_client = Geocoding::FakeGeoClient.new

    # generate warning if the spec doesn't cause a hit to Geocoding.client
    Geocoding.warn_if_not_received(:client).and_return(@geocoding_client)
  end
end

Not at this point, and I don't think it would be a slam dunk to add.

You can use before/after all in the outermost group:

describe "thing" do
  before(:all) { set_up_measurements }
  after(:all)  { report_measurements }
end

+1

It might not surprise you that I prefer to focus on behavior over implementation (though it might surprise some people who think I like to mock too much! ;)), however ...

-1

... there are absolutely valid cases for focusing on type. In rspec-rails, for example, mock_models need to lie about their type to Rails' internals in order for things to run smoothly. There are, therefore, examples like:

  mock_model("User").should be_a(User)

Any sort of factory that might generate objects of different types in different contexts would warrant this as well.

That said, I'll guess that @slavix's motivation here is that there are ParentModel specs and he doesn't want to duplicate them for ChildModel. If that's true, then a shared group is definitely a better option for a number of reasons. The most obvious one is that ChildModel is free to override behavior defined in ParentModel, so the fact that ChildModel < ParentModel is no guarantee that they behave the same way.

HTH,
David

Why would you want a warn? I can't get my head around this.

There's no support for this in rspec-mocks. You can do the following, but I would not recommend it:

before do
  @geocoding_received_client = false
  Geocoding.stub(:client) do
    @geocoding_received_client = true
    @geocoding_client
  end
end

after do
  warn "Geocoding did not receive :client" unless @@geocoding_received_client
end

David

Doesn't --profile only return the ten slowest examples? I have
thousands of specs, so I need a little more data than that.

Subject: [rspec-users] rspec and testing IO
Message-ID: <50E4D18C-3F36-4707-82F1-6166AFB77000@mac.com>

I have a class that expects some input via 'gets'.  I found that, when testing, I can do something as simple as this:

@foo.stub!(:gets) { "stuff\n" }

However that only works in the most simple case.  In my case the class asks a series of questions that require a yes/no answer culminating in some end state.  The class then asks if the user would like to go through the questions again and waits for a response of yes/no.  If I want to test a single run through the questions (answering 'yes' to all of them) and I stub 'gets' to always reply with 'yes' then I have no way of breaking out of the loop.  The test I'm running dies and complains of the stack being too deep.

So, my question is this:

How do folks typically go about testing classes that take input from stdin?  I can post more code if necessary but this is a pretty simple question to which, I'm sure, there is a reasonable solution.

Thanks!

Justin

Two ways to approach this. On the unit level, you can stub "gets" and return
a different value each time:

stubs(:gets).and_return('yes', 'no', 'yes', 'yes', 'no')

Each time "gets" is called it will return the next value.

On a more high level, I would recommend using the aruba gem with RSpec. Here
is how I've done it in my own code:

Let us know if any of that works.

Subject: [rspec-users] rendering xml with haml through render_template is
	invalid
Message-ID: <p06240806ca8f21bca5c2@[192.168.1.122]>

I have some controller tests for validity of restful XML responses.

I'm using haml to generate the xml.

When I test externally with curl the response is well-formed XML.

However when I test the controllers with rspec2 the response is invalid XML.

The following code is part of an rspec shared_example:

   it "renders the requested #{model_ivar_name_lambda.call} as otml without error" do
     @model_class.stub!(:find).with("37").and_return(@model_ivar)
     get :show, :id => "37", :format => 'otml'
     response.should render_template(:show)

The response body includes both well formed and invalid XML:

For example running this test:

   bin/rspec spec/controllers/embeddable/open_responses_controller_spec.rb

I've extracted part of the response below to show the <OTCssText> element is not closed and is invalid XML

   <cssBlocks>
     <OTCssText local_id='otml_css' src='/stylesheets/otml.css'>
   </cssBlocks

Here's the same extract showing valid XML when the request travels through the entire app:

   curl http://localhost:3000/embeddable/open_responses/3.otml

   <cssBlocks>
     <OTCssText local_id='otml_css' src='/stylesheets/otml.css' />
   </cssBlocks>

Haml normally uses the Rails 3 default format of :html5 for rendering which will render complete elements without a '/>' ending.

However it seems that when going through the whole stack the fact that we've registered 'otml' as a 'text/xml' mime_type causes 
Haml to use the :xhtml format.

   Mime::Type.register "text/xml", :otml

However if I specifically set the Haml format to :xhtml in the spec test like this:

   it "renders the requested #{model_ivar_name_lambda.call} as otml without error" do
     Haml::Template.options[:format] = :xhtml
     @model_class.stub!(:find).with("37").and_return(@model_ivar)
     get :show, :id => "37", :format => 'otml'
     assigns[@model_ivar_name].should equal(@model_ivar)
     response.should render_template(:show)

Now the response is well-formed XML.

But this is disturbing because I am not doing that in the application.

It may be a problem with rspec, rspec-rails, haml or the ActionController::TestResponse rspec delegates to ... ???

Thanks Justin, that'll work just fine for my simple case and, in the mean time, I'll look in to aruba also.

Much appreciated!

Are you using a mock model or a real one? If mock, try a real one and see what happens.

rspec-rails acts as a thin wrapper over the Rails testing framework, which does a lot of things to simulate the runtime environment for you. It's doubtful that rspec is the culprit, but we can rule that out definitively by writing a similar test in the Rails testing framework:

class ThingControllerTest < ActionController::TestCase
  test "...." do
    # create a real model
    get :show, :id => "37", :format => 'otml'
    assert_template "show"
  end
end

Does that fail the same way?

This just came in really handy. I'm helping out now and again with a new Rails project using Spork and Guard. We moved some code out into lib/ and set up a separate `guard 'rspec'` to only monitor lib/ and spec/lib/. Took a bit of jiggery-pokery to make it not use Spork and Rails but it works now, and is as fast as RSpec runs get.

I'm probably late to the party with Guard, as I used AutoTest for years. But for the benefit of anyone new to either: if you're not doing continuous testing, _you should be_*, and if you are, you should never be happy with how fast they run. They can always be faster. Always. Guard makes it much easier than AutoTest to tune the test runs, and does other cool stuff too.

*It was David Chelimsky who said the exact same thing to me on this list, what- 5 or 6 years ago? One of the best pieces of advice I ever got. Funny how for all the new fangled technology we've had in the mean time (and for all I've learnt since), I'm still using the same basic development process I used back then?

Subject: [rspec-users] rspec rake task + bundler: feedback requested
Message-ID: <5B24ADDF-1EB8-4EF8-9F0A-205C91A6ED7D@gmail.com>

Hey folks,

RSpec's assumption that the existence of a Gemfile means you want to use Bundler to configure runtime environment is flawed. We added a skip_bundler option to the rake task, but that was a temporary hack to get us through a release without breaking existing suites.

This still presents a problem for anyone who doesn't have Bundler installed, and is contributing to an open source project that does use Bundler for installing gems as a convenience, but doesn't need it for the runtime environment. I'm sure there are other cases.

If this topic interests you, please take a look at https://github.com/rspec/rspec-core/issues/454 and my proposed fix at https://github.com/rspec/rspec-core/commit/f90b9f5c6ce5efdfb5cf18efbe27adf87d0fa848. I think this is a good solution to the problem, but I want to get some feedback before merging this to master.

Please comment in the issue and/or the commit on http://github.com/ rather than here. I'd like to keep the conversation in one place.

Thanks,
David

end users can read the Cucumber tests.  Is there a way to generate
user-readable tests from Rspec tests or Watir tests?

You can write your own Formatter[1] if the existing ones don't work for you.
The default RSpec document format is already available[2] - just pass
`--format doc` as a param when running the specs.

Best,
Sidu.

Message-ID: <538e9228-5231-4904-bf80-378fc52f3332@i14g2000prd.googlegroups.com>

Hello All,

 I followed steps to install Rspec as in the link pasted below.

http://www.pmamediagroup.com/2009/04/tutorial-install-rspec-rails-factory-girl/

I have jRuby on Rails installed on my machine.Hence all commands need
to be run with jruby -S extension.
However when I run the jruby -S rake spec command,I get the following
error as shown below.

What does the error indicate,I tried commenting all lines having
drop_database statement in them.
Another thing is that the database already has tables and by using the
tutorial I have just added another table for the bank-account.
Kindly let me know what exactly needs to be done in this case

Thanks & Regards

I am mostly testing Java web applications (I do not know Rails).  Will 
Formatter[1] work without Rails?

I watched the video and it looks like it just outputs test results.  The 
output should be a test-narrative similar to:
  Given some context
  When some event occurs
  Then I expect some outcome.
Then the end users will review the test-narrative before we start 
development. Is there a tool that can generate a test-narrative from 
Rspec tests or Watir tests?

Thanks Sidu.

See https://www.relishapp.com/rspec/rspec-core/docs/command-line/format-option. Also, you can get a good start by typing `rspec help`.

When you run a spec suite, RSpec delegates to Rails to do the same work it does before and after a test suite. One task it runs is db:schema:load, which is defined in Rails. It asks the configured database for a list of tables and then tries to drop and recreate them. This ensures that any data from a previous run is removed, and the schema for the test db matches that of the development db.

The message tells you the underlying problem: there are database constraints that are not allowing the tables to be deleted in the order in which the rake task is trying to delete them. For whatever reason, the active record adapter you are using is not invoking a cascading delete. What adapter are you using? What database? Also, what other db-related gems do you have in the app? Just type `jruby -S bundle show`.

Now I understand better.  Goggling "rspec formatter" shows that there 
are formatters for progress, documentation, and html.  This will make 
more sense after I learn Rspec.

Thank you David and Sidu.

Subject: [rspec-users] Assertions for asynchronous behaviour
Message-ID: <A66FFDAB-4876-481E-BEF7-A1928CD780BF@mattwynne.net>

Hi all,

In GOOS[1] they use an assertion called assertEventually which samples the system for a success state until a certain timeout has elapsed. This allows you to synchronise the tests with asynchronous code.

Do we have an equivalent of that in the Ruby / RSpec world already? I know capybara has wait_until { } but that's fairly rudimentary - the failure message isn't very helpful. Is there anything else already out there?

Sounds like Matt is going to make us this matcher! :)

Sure. "wait_for" is a method Brian Takita and I originally wrote for
use in Selenium tests, then IIRC it made it into the Selenium gem and
now lots of libraries use it (or their own version -- I make no patent
claim on polling :-)). The wait_for I remember allowed you to
customize the failure message. Let me go see if it's on GitHub or
anything...

Ah, here's one:
https://github.com/pivotal/selenium/blob/master/lib/selenium/wait_for.rb

(Maybe I should put it in Wrong.)

I believe remarkable_activerecord and shoulda-matchers have conflicting
API's? Also, looks like you need to use methods, rather than symbols as
arguments:

it { should have_one(:tradable).through(:trade_order) }

Subject: [rspec-users] Mocking expectations on I/O operations
Message-ID: <F8F3C86CDFF446D59A78BB60E2EAECF4@stardotstar.com>

I'm speccing a small lib which manipulates image files using mini_magick.
The lib creates various temporary files during the process, the lib then cleans up the temporary files at the end.

I'm trying to mock expectations that the calls are made to File#delete

Eg...
File.should_receive(:delete).once.with("#{generator.tmp_path}-full\.png")
File.should_receive(:delete).once.with("#{generator.tmp_path}-screen\.png")
File.should_receive(:delete).once.with("#{generator.tmp_path}-shadow\.png")

The method in the lib that does this is:

Class IconGenerator
...

 private

 def cleanup
 # remove temporary files created during 
 # image manipulation
 ['-full','_screen','_shadow','_back_shadow'].each do |f|
 File.delete "#{tmp_path}#{f}.png" if File.exists? "#{tmp_path}#{f}.png"
 end
 end
...
end

The expectations work fine, however, I also have an after block which also calls File.delete to clean up the final version of the manipulated test image

after(:each) do
 # cleanup manipulated image
 File.delete out_dir.join('MenuIcon.png') if File.exists? out_dir.join('MenuIcon.png')
 end

The File.delete call in the after block fails because its calling the mocked version of File.delete
This results in the following error:

Failure/Error: File.delete out_dir.join('MenuIcon.png') if File.exists? out_dir.join('MenuIcon.png')
NoMethodError:
undefined method `=~' for #<Pathname:/Users/robaldred/Sites/egg/tmp/MenuIcon.png>


My next step was to stub the write method for every instance of MiniMagick::Image
However I will then no longer be able to test the cleanup because the delete method will never be called if the files don't exist.

I'm pretty sure I'm going about this the wrong way and making it difficult for myself here.
Appreciate any help & feedback

Thanks

Rob

Give `File.unstub(:delete)` in your `after` block.

Hi David,
So does that mean that I need to manually delete all other tables for
the rake command to run successfully?

Thanks Justin,

The method `delete` was not stubbed or was already unstubbed

That needs to happen but the activerecord adapter you are using should handle it implicitly for you. Which one are you using?

Hi Rob

For reasons I could go into, when I'm coding myself I don't usually stub  out file system access or other third party systems. Rather, I write an adapter that behaves in the way I expect and test it using the real file system, then test the rest of the system against a mock. That avoids this category of problem.

What you're doing here appears to be mixing both real (from mini_magick) and stubbed (your own library's) calls to filesystem code, and I think it's the asymmetry that's biting you.

I could explain the above in more detail*, but in lieu of that, here's another angle: can you run the code in a subdirectory per image and nuke that after? That way you only have one point to hit for the cleanup.

HTH

Ash

If you've installed the gem via bundler, you'll need to either do
'bundle exec rspec' or run the build via rake (do `rake -T | grep
spec` to list all the spec related tasks). You should also take a look
at http://blog.davidchelimsky.net/2011/07/18/stop-typing-bundle-exec/

In any event, most editors and IDEs allow you to run your test(s)
inline using a shortcut, so you may want to explore that option as
it's far more convenient/productive than switching to a shell.

Best,
Sidu.

 Hey Ash, 
I like the idea of a wrapper.
In fact I use this method for methods that need to shell out 

Maybe your right, the subdirectory would probably a better safer way of organising the temporary files.
I'll have a re-think.

Thanks for the info.

Rob

Woops, you're using expectations, not stubs. Try `File.rspec_reset`

Hi Rob,

First of all perhaps you are testing the wrong thing in the wrong place.

As cleanup is a private method, why are you specifying (in this spec
how it works). As far as IconGenerator is concerned currently all you
care about is that it calls cleanup. You're not interested in how that
cleanup is implemented. If you want to specify how the cleanup works
then make cleanup public - either in this class, or perhaps better yet
in another class. e.g.

describe "Cleanup.clean"
  it "should delete files"
  end
  ...
end

describe IconGenerator
   ...
   it should cleanup
      Cleanup.should_receive(:clean) ...
end

Once you separate the cleanup spec from the IconGenerator spec then
the clash should disappear! You'll never have to mock File.delete

HTH

I thought that too, but then it occurred to me there's a chance mini_magick isn't using Ruby's filesystem code (it might be writing to the FileSystem with native code for example), so I didn't put this in to confuse the situation. But yes, if it could be done, FakeFS might work well here.

Hi,
I am using the jdbc adapter because the application I am using is
being developed on Jruby on Rails.

Thanks for all the ideas. I just rolled my own which expects a block with an assertion in it:

https://gist.github.com/1228927

Could we put this into RSpec somewhere? I'd rather not dump the source into The Cucumber Book - it's too low level. I could put it into it's own little gem but that seems like creating clutter in the gemsphere.

WDYT?

have_xpath is a Capybara matcher that defines its own failure message:

"have_[xpath]" is a custom matcher in Capybara. So, the answer would be no.

It's not actually RSpec-specific. I'll put it (or probably a hybrid
between your new code and my old code) into Wrong and you can use it
via the wrong rspec adapter.

def two
  rand(3)
end

require "rspec"
require "wrong/adapters/rspec"
describe "two" do
  it "should eventually be half of four" do
    eventually { (two + two).should == 4 }
  end
end

should work soonish...

Thanks!

I know it's not RSpec specific. I suppose my motivation is I want to keep the number of tools / gems we have to mention in the book to a minimum. Since we're already using RSpec in the book already it made sense to me if it became part of the RSpec assertion toolkit. I'd have thought it would be useful to other RSpec users too.

I've never used Wrong, only read about it--and I like the idea very much, I must say. Is there any danger of adverse effects (other than an extra line the Gemfile) if we have to use the Wrong RSpec adapter in the book alongside the existing vanilla RSpec assertions?

There shouldn't be, but I'd love for more people to verify that. The
adapter source is at

https://github.com/sconover/wrong/blob/master/lib/wrong/adapters/rspec.rb

(It doesn't actually do much, just includes Wrong inside RSpec's
ExampleGroup. The bulk of that code is in case anyone uses the Wrong
feature "alias_assert" which allows users to define their own DSLy
name for assert. I like "expect" but RSpec already has its own
"expect"; David kindly provided a way to cleanly remove RSpec's
"expect" before defining my own, but I couldn't quite get it to work
so I'm still using the brute force way which just chops it out using
Ruby's "Module#remove_method" method. In any case, none of that is
relevant unless users go out of their way and call
"Wrong.config.alias_assert :expect, :override=>true" which most won't
do.)

There's a semantic issue in your eventually method that I'd like to
discuss. My wait_for[1] and friends take a *predicate* (in the form of
a block) and wait for it to return true(ish). Your eventually[2]
ignores the return condition, and merely waits for it to not raise an
error. I think using a predicate is more useful, and strictly no less
powerful since the waiter code will *also* wait for it to not raise an
error, so you could do *either* this

    eventually { rand(10) == 0 }

or this

    eventually { rand(10).should == 0 }

and if, after 2 sec or whatever, it keeps either being false or
raising an ExpectationNotMetError, then the waiter will itself raise
an ExpectationNotMetError.

IOW, should the following pass or should it fail?

    eventually { false == true }

 - A

P.S. (Lurkers please feel free to chime in too. :-)

To be honest, I just ignored the true / false version in my implementation because I want a helpful error message when the test fails, rather than a crude TimeoutError or whatever.

I'm ambivalent about this: I would worry that allowing falsiness to cause an assertion to be raised is not idiomatic RSpec, but perhaps it is idiomatic Wrong, since you can do all that magic to infer an error message anyway, right?

I think as long as I can use my own assertions too I don't have any objections to it doing both.

I hear you.

I hope so... I mean, uh, yes! Definitely! :-)

Subject: [rspec-users] preferred place for methods used by both rspec and

Message-ID: <alpine.OSX.2.00.1109211927180.25624@vincent.local>

Hi,

I have some helper methods such as:

def mock_omniauth
  OmniAuth.config.test_mode = true
  OmniAuth.config.mock_auth[:facebook] = facebook_user
end

def facebook_user
  @facebook_user ||= HashWithIndifferentAccess.new(YAML.load(File.read("#{Rails.root}/test/fixtures/fb_user.yml")))
end

that I want to use in both cucumber step definitions and rspec.  Is there a
preferred place to store this code, or is it standard practice to just define
them in a module in config/inititalizers and include that in both cucumber's
env.rb and rspec's spec_helper.rb?

Thanks.

This doesn't come up that often so there is no established convention. I've put such code in files in spec/support and included it from the features directory before. I'm sure the other way round would work just fine.

config/initializers is about application initialization IMO, so I wouldn't put this material there.

Anybody else?

I agree with David that config/initializers isn't the right place as 
that would load test-related code into your application in production.

I create a folder in Rails.root for shared code and then require it as 
necessary in RSpec and Cucumber. My current directory name is 
test_support, which I'm not terribly fond of, but doesn't really matter 
so I haven't wasted the brain energy to rename it. The benefit of 
keeping shared code in a folder external to both tools is I can totally 
remove one tool without the other breaking. If you keep the shared code 
inside one or the other, you have to be careful about changing whichever 
one hosts the shared code.

Peace.

The rspec command is designed to be run from the project root. Try:

	application request spec
Message-ID: <9933335.535.1316077690559.JavaMail.geo-discussion-forums@yqnh42>

Hello!

I am learning to use RSpec for testing Rails 3.1 applications - really 
enjoying using it so far.
In testing for the presence of assets (e.g rails.png), I've been using:

  get "/assets/rails.png"
  response.status.should be(200)

After some reading about the Rails 3.1 asset pipeline I discovered the 
"asset_path" helper. Is it possible to access this helper in a request spec? 
I have not had any success so far:

  get asset_path, "rails.png"
  response.status.should be(200)

Gives:

  undefined local variable or method 'asset_path'.

Any help with this would be appreciated.

Best,

Silumesii

Hey there,

I am needing to stub a 'current_user' method in an Rspec/capybara
request spec. The method is defined in ApplicationController and is
using helper_method. The method should simply return a user id.

Alternatively, I could fix my problem by setting 'session[:user_id]'
in the spec (which is what 'current_user' returns)... but that doesn't
seem to work either.

Are either of these possible? Thanks!!!

Thanks Jack. A couple of others have offered to do the same and I'll be coordinating the effort shortly. Just returning from a couple of weeks vacation, so lots of catching up to do. I'll be in touch within the next week.

Capybara was designed to force the dev to build true request specs. Meaning, you cannot tamper with cookies, request headers, etc. directly. You have to go through the app - clicking links, visiting paths, etc.

So, you're going to have to go to the authentication page and login before hitting the pages you actually want to test.

T/U tests are just Ruby classes, so you can do things like "include UserAssertions".

"asset_path" isn't a routing URL helper, it's a Sprocket helper. Try this:

# in spec_helper.rb
config.include Sprockets::Helpers::RailsHelper, :type => :request

Subject: [rspec-users] how to test identical behavior without being
	redundant?
Message-ID: <alpine.OSX.2.00.1109261405340.54012@vincent.local>

I've got many models that have this declared:
  has_many :notifications, :as => :notifiable, :dependent => :destroy 
    

...  And so I have many model specs such as:

describe Reply do
  
  it "should eliminate any associated notification records when destroyed" do
    reply = create_reply
    reply.notifications.should_not be_blank
    
    reply.destroy
    reply.notifications.reload.should be_blank
  end
  
end

describe Post do
  
  it "should eliminate any associated notification records when destroyed" do
    post = create_post
    post.notifications.should_not be_blank
    
    post.destroy
    post.notifications.reload.should be_blank
  end
  
end

etc...

Is there an ideal way to dynamically generate this for any models that respond
to notificaions so that I don't have redundant noisy tests?


Thanks.

It's possible, I'm involved in one project that has been using
test::unit in the past and has still not completely transitioned to
RSpec (but RSpec is the default for new code). Basically you just run
"rake test" then "rake spec".

After a week of stealing minutes, I eventually wrote eventually!
Please check this out and give me feedback. I can ship it in a new
Wrong gem as soon as you all tell me it's ready.

docs:
https://github.com/alexch/wrong/commit/cae852f09a3d4dcb3f014b486a10d5eb7a10e7f5

test (spec):
https://github.com/alexch/wrong/blob/master/test/eventually_test.rb

code:
https://github.com/alexch/wrong/blob/master/lib/wrong/eventually.rb

The only major feature I haven't done is editing the error message
from inside the block, since Wrong seems to do a good job of this on
its own. If the block contains a "should" or a Wrong "assert" then it
ends up looking like it just got called and failed the final time.
It'd be nice if I could sneak into an exception and append "(after 5
sec)" to e.message but I don't know if I want to go there...

Subject: [rspec-users] Custom Formatter: Getting Text from It Method
Message-ID: <6ba93974-a471-476f-8943-ad7849b219fe@db5g2000vbb.googlegroups.com>

Hey all.

I've been playing around with RSpec custom formatters to see how much
flexibility there is. One thing I've been trying to see is if I can
print the contents of a variable that's in an example (it) method. So,
for example, here's what I have in my specification:

  it "should display results range" do
    search_for("star wars")
    @browser.text.should match(/Showing .* of .* Results/)
    intent = "Text 'Showing .* of .* Results' shows after 'Star Wars'
search"
  end

Notice the line with intent there? I realize this is not what most
people would do with RSpec. The reason I'm doing this is because I'd
like viewers of the test results to see the exact condition that was
tested for in the should if they want to -- without having to read the
code. Again, I'm just experimenting.

What I'm trying to do is figure out how I could use a custom formatter
to print out that intent text. I know that the example_passed method
in the formatters contains elements like example.description that
prints out the text of the it method. But trying @output.puts
example.intent does not seem to work.

Is there a better way to do what I'm trying to do here? Again, I
realize that most people are happy with the describe and it text being
printed out. But sometimes people -- like my business users -- want to
check the actual condition that was checked for, without having to
read Ruby code.

Any pointers or tips would be greatly appreciated.

- Jeff

Am I correct in understanding that the point of using let is that it can
minimize database calls due to memoization?

describe "#something" do

  let(:something) = Something.groovy_scope

  it "does x" do
    something.first.x.should have_coolness
  end

  it "does y" do
	 something.first.y.should_not have_coolness

  before :each do
    @something = Something.groovy_scope
  end

  it "does x" do
	 @something.first.x.should_not have_coolness
  end

  it "does y" do
	 @something.first.y.should_not have_coolness
  end
 
end

...

Is that the proper usage?

Proper usage, sure, but the memoization is only within each example - not across examples. That way you can do this:

let(:thing) { Thing.new }

it "does something" do
  thing.blah
  thing.whatever
  thing.yet_again
end

In that case each reference to thing returns the same object.

Make sense?

Hmm.. now I am confused...

What is the difference between:

describe "Foo" do

  let(:foo) { Foo.new }

  it "is tubular" do
    foo.bar
    foo.baz
  end

  it "is gnarly" do
    foo.gnarl
    foo.wurd_up
  end

end

vs.

describe "Foo" do

  before :each do
    @foo = Foo.new
  end

  it "seems just as tubular as the foo w/ let" do
    @foo.bar
    @foo.baz
  end

  it "seems just as gnarly as the foo w/ let" do
    foo.gnarl
    foo.wurd_up
  end

end

I am not seeing any difference...?

The variables defined inside the example are out of scope in the formatter. You can do something like this:

==================
require 'rspec/core/formatters/base_text_formatter'

module ExtraDoc
  def example_passed(example)
    example.description << ": #{example.metadata[:extra_doc]}"
  end
end

RSpec::Core::Formatters::BaseTextFormatter.send(:include, ExtraDoc)

describe "something" do
  it "does something", :extra_doc => "with extra sauce" do
  end
end
==================

Output from `rspec --format documentation` is:

==================
something
  does something: with extra sauce
==================

That said, I'd focus on naming the examples better so they serve the needs of all readers.

HTH,
David

There is not, really, other than how the declaration of foo is expressed and referenced. This evolved out of a common pattern in TDD:

1:

describe "something" do
  it "does something" do
    thing = Thing.new
    thing.do_something.should have_some_outcome
  end
end

2:

describe "something" do
  it "does something" do
    thing = Thing.new
    thing.do_something.should have_some_outcome
  end

  it "does something else" do
    thing = Thing.new
    thing.do_something_else.should have_some_other_outcome
  end
end

Now there is duplication so we can refactor out the declaration of thing. It takes less work and is less error prone to change it to a let declaration than to change the references to thing to an instance variable declared in a before hook.

Cheers,
David

One thing I noticed, and something that always catches me out is the 
fact that the 'let'ted object doesn't get instantiated until it gets 
referenced. Therefore,

describe "all" do
     let(:foo) { Foo.create! }

     it "returns the created object" do
         Foo.all.should include(foo)
     end
end

... fails, since at the time of calling :all, the 'foo' object hasn't 
been referred yet, and hence the block hasn't executed. "Foo.all" in the 
case above returns an empty array, which wouldn't have been the case 
with an instance object created in "before(:each)".

That's one of the benefits of let :) You can use it to declare objects but they only get instantiated when you reference them.

So regarding objects persisting over multiple examples--  I was told repeatedly
by experienced RSpec peeps to not use before(:all)...

But in a case like:

before(:each) do
  @user = create_user
  create_user_item(:user => @user)
end

it "has an item" do
  @user.user_item.should_not be_nil
end

it "rocks the house" do
  @user.user_item.should respond_to(:rocks_the_house)
end

..etc...

It seems like this is an instance where before :all, really would shine because
it would not require records to be repeatedly created...

Do you guys feel like before(:all) is just bad because of the possibility of a
method call in one example changing the state and therefore breaking future
examples and not having it be clear as to why.. ?

I don't know if object creation (including the corresponding database 
calls) are really expensive enough that I would worry about optimising 
that (unless you're getting it anyway, without losing anything in the 
process, like with 'let'). Occasionally, for some reason I'll end up 
using a 'before(:all)' for one isolated scenario, but inevitably a few 
months down the line, I'll end up wasting a couple of hours on a weird 
failing test, until I look closely enough to notice the ":all".

So, unless I'm doing something that's prohibitively expensive (I haven't 
found anything that would qualify in any of my projects) I'm not likely 
to create anything in a 'before(:all)'.

Have you seen Wrong? You just described its intent :-)

http://github.com/sconover/wrong

If you get a source code block you can use the Chunk class in Wrong to parse it and pull out useful snippets. But you probably won't have access to the binding and its values at that point.
