testing shared behaviors

[Semin Lee]

Hi guys,

I was wondering if there is an easy to do some tests on shared
behaviors using Shoulda (or test:unit). I am extracting shared methods
(or behaviors) out of individual classes and make them as a separate
module to be shared, but I don't find an easy and DRY way to test this
shared behaviors.

Rspec seems to provide this kind of functionality by using external
shared_examples (http://rspec.info/examples.html), but I don't want to
switch back to Rspec because I am already addicted to Shoulda's
terseness. :)

What do you guys think about this? Any suggestions?

Cheers,
Semin

Hi Semin,
I'm not sure if I understand exactly what you're asking, but I
think you could just write a test to test your module methods (which I
assume you are mixing into a class by the include keyword?)
If you need to test it in the context of a class, just create a dummy
class which mixes in your module:

class Foo; include MyModule; end

class MyModuleTest < Test::Unit::TestCase

context "An instance of a class with MyModule methods mixed-in" do
setup do
@object = Foo.new
end

should "do some stuff" do
assert @object
end
end

end
