Instance Method Details

#describe(*args, &block) ⇒ Object Also known as: context

Creates and returns a class that includes the ExampleGroupMethods module. Which ExampleGroup type is created depends on the directory of the file calling this method. For example, Spec::Rails will use different classes for specs living in spec/models, spec/helpers, spec/views and spec/controllers.

It is also possible to override autodiscovery of the example group type with an options Hash as the last argument:

describe "name", :type => :something_special do ...

The reason for using different behaviour classes is to have different matcher methods available from within the describe block.

See Spec::Example::ExampleGroupFactory#register for details about how to register special implementations.

  Spec::Example::ExampleGroupFactory.assign_scope(self, args)
  Spec::Example::ExampleGroupFactory.create_example_group(*args, &block)
end

#share_as(name, &block) ⇒ Object

Creates a Shared Example Group and assigns it to a constant

share_as :AllEditions do
  it "should do all editions stuff" ...
end

describe SmallEdition do
  it_should_behave_like AllEditions

  it "should do small edition stuff" do
    ...
  end
end

And, for those of you who prefer to use something more like Ruby, you can just include the module directly

describe SmallEdition do
  include AllEditions

  it "should do small edition stuff" do
    ...
  end
end

end

#share_examples_for(*args, &block) ⇒ Object Also known as: shared_examples_for

    ...
