Documentation
smallCheck :: Testable IO a => Depth -> a -> IO () Source #
A simple driver that runs the test in the IO monad and prints the
results.
smallCheckM :: Testable m a => Depth -> a -> m (Maybe PropertyFailure) Source #
Use this if:
- You need to run a test in a monad different from
IO - You need to analyse the results rather than just print them
smallCheckWithHook :: Testable m a => Depth -> (TestQuality -> m ()) -> a -> m (Maybe PropertyFailure) Source #
Like smallCheckM, but allows to specify a monadic hook that gets
executed after each test is run.
Useful for applications that want to report progress information to the user.
