I’m curious about standards on unit testing modules.

I have a module file in my lib/ directory. Should I create a unit test  
in test/unit directory and test it as I would any other model?

Is there any kind of naming convention used for unit test files for  
modules (some\_name\_test.rb or some\_name\_module\_test.rb)?

Don’t know if there’s a standard but I think it makes sense just to  
test  
it in test/unit.

Don’t know. If it’s lib/some\_name.rb then test/unit/  
some\_name\_test.rb  
seems ok with contents:  
require File.dirname( **FILE** ) + ‘/…/test\_helper’  
class SomeNameTest \< Test::Unit::TestCase  
…  
end  
Works for me at the moment.
