RSpec 2 / Rails 3 autoload

Testing RSpec
1

Hi

For the last 18 months I’ve been used to writing specs like this, which
was written with Merb 1.1.0.pre and RSpec 1.3:

module LanguageRepository
describe DataMapperAdapter do
it_should_behave_like “Contract: LanguageRepository”

  def language_repository
    DataMapperAdapter.new
  end
end

end

This will happily find and instantiate
::LanguageRepository::DataMapperAdapter from the
models/language_repository folder.

However, using Rails 3.0.0.beta from master and Rspec 2.0.0.beta.2, I
get the following error:

  1. LanguageRepository::DataMapperAdapter storage and retrieval can
    store
    a Language and retrieve it by code
    Failure/Error: DataMapperAdapter.new
    uninitialized constant
    Rspec::Core::ExampleGroup::NestedLevel_8::DataMapperAdapter

I have to change it to this to make it work:

  def language_repository
    LanguageRepository::DataMapperAdapter.new
  end

Now, having just changed two moving parts (RSpec and web framework) I’m
not sure what correct behaviour is on anything. I don’t know how Rails
code auto-loading works, or how RSpec interacts with it.

Is the above behaviour a bug or a misunderstanding on my part?

Cheers
Ashley
