Modules and TestUnit

[Daniel Berger]

Hi all,

If I have a module, and I want to test that module's methods
independently within TestUnit, what is the best approach?

Am I obligated to define module_function for each method so that I can
do assert_equal("foo",MyModule.foo)? Or am I just supposed to
"include" the module in the subclass of Test::Unit::TestCase and use
it that way?

Advice appreciated.

I've done the latter with much success. Unless your module modifies the
class in some way that interferes with the test case running, you
should be all good.

If the module does interfere with tests running, it's pretty easy to
just do:

class ModuleContainer
include MyModule
end

def setup
@module = ModuleContainer.new
end

But including it right in the TestCase is obviously a bit simpler.
