I can do that indeed, and I guess I could reimplement everything I have at the moment on top of HUnit.
However, an important part of functionality isn't there at the moment — golden file management. You should be able to say, "for this test, take its current output and write it to the corresponding golden file".
In order to do that, you need to have access to the list of golden tests in the suite. This is where implementation details of different test frameworks start to matter. Probably one can make an abstraction over test frameworks that would give the list of all golden tests. (Although when you start abstracting over test frameworks, which are abstractions themselves, it becomes somewhat funny.)
Ok, makes sense. I'm looking forward to give it a try, and see how it compares to using operating system primitives (say `cp') for "golden file management".
Speaking of such functionality, correct me if I'm wrong, but neither HUnit nor hspec won't be able to support it anyway, because they represent tests as opaque IO actions.
It would be easy to extend Hspec to support this in the same way you extend test-framework to support this. It requires existentials; the only substantial difference that I can see is that test-framework already uses existentials, while Hspec does not. Cheers, Simon
