I'm working on a series going over the source code for rspec, and I ran into something interesting with ExampleGroup and SharedExampleGroup. I was wondering if anyone could shed light on it.<br>[NOTE: I'm working through the code for my own edification in learning Ruby. Ruby has some features that I think are incredibly cool, so I'm using a concrete implementation (RSpec) as a learning tool to see them implemented. Along the way, I figured I would ask questions that were confusing to me. So, please bear with me and please please please do not take this as criticisms/attacks]
<br clear="all"><br>I expected to see SharedExampleGroup < ExampleGroup, but, instead, I saw SharedExampleGroup < Module. This is incredibly confusing to me. I realize that they don't even need to have any relationship to each other since they get their shared functionality through the module ExampleGroupMethods, but it still seems a bit odd to me that they don't have a hierarchical relationship.
<br><br>If there is some hidden meaning, I'd love to hear it. I'll post it as an update to the blog entry, too.<br><br>Oh, and here are the links to the first few parts of the series if anyone is interested: It looks like I'll be able to get about a post a week on it.
