Seems to me that including the same shared example group twice in the same
"describe" block is a bit of an abuse, to be honest. I don't think it was ever
really intended to be used in that way.
Your shared_examples_for should be written in such a way that they don't need
to reference "<i>"; ie:
shared_examples_for "Comparable" do
it 'defines equality' do
subject.should eq(subject)
end
end
And then you use it like this:
describe Integer do
[1, 2].each do |i|
describe i do
it_should_behave_like 'Comparable'
end
end
end
Obviously this is a toy example that you've given us, and I don't see why you'd
want to test 1 and 2 like that, but for the purposes of illustration... The
specdoc output for that would look like:
Integer
1
it should behave like Comparable
defines equality
2
it should behave like Comparable
defines equality
I know you probably have some real example in mind hiding behind that toy
example, but I believe anything you want to test can be written in the same way
(ie. without needing to inject the "<i>" into your shared examples).
Cheers,
Wincent
