[Wtr-general] Breaking code into several classes and methods

[Jeff Fry]

Hi all,

I'm using my trusty pickaxe plus various code samples to try to take a
script of mine and break it up a bit into several classes and methods within
classes...and getting stuck.

When I run the code below, I get:
test_benchmark_page(TC_PerformanceBenchmark):
NoMethodError: undefined method `link_to_text' for #<Page:0x2e28b94>
    performance_benchmark2.rb:56:in `benchmark'
    performance_benchmark2.rb:54:in `times'
    performance_benchmark2.rb:54:in `benchmark'
    performance_benchmark2.rb:69:in `test_benchmark_page'

It complains about this line in particular:
      if $ie.link(:text, page.link_to_text).exists?

But when I try it in irb it seems that page.link_to_text shouldn't be a
problem:
irb(main):040:0> $page = Page.new("c_eastwood",
"/view?id=%239202a8c04000641f800000000056de6", "Mystic River")
=> #<Page:0x2dafe24 @link_to_test="Mystic River",
@url="/view?id=%239202a8c0400641f8000000000056de6", @key="c_eastwood">
irb(main):041:0> $page.link_to_test
=> "Mystic River"

Here's my relevant code:
class TC_PerformanceBenchmark < Test::Unit::TestCase
  ...
  def benchmark(page)
    1.times do
      $ie.goto($url_root + page.url)
      if $ie.link(:text, page.link_to_text).exists?
        $results_array << $ie.down_load_time.to_s
        p '$ie.down_load_time: '+$ie.down_load_time.to_s
      else
        $results_array << 'e'
        p 'e'
      end #if
    end #do
  end

  def test_benchmark_page
    login($url_root, $user, $pw)
    $page = Page.new("c_eastwood",
"/view?id=%239202a8c04000641f8000000000056de6", "Mystic River")
    benchmark($page)
  end

end #class

class Page
  def initialize (key, url, link_to_test)
    @key = key
    @url = url
    @link_to_test = link_to_test
  end
  attr_reader :key
  attr_reader :url
  attr_reader :link_to_test
end

Any ideas?

Thanks,
Jeff
