In relation to a previous question, I'd like to have multiple test folders for different types of test and be able to execute the tests contained in each folder with a separate SBT action.
For example, an action 'test-unit' would run only the tests contained under the folder src/test/scala/unit, and a 'test-functional' action would run only the tests under src/test/scala/functional. How would we write actions to do this?
