Setting expectations

expectationFailure :: MonadIO m => String -> m ()

This is just an alias for HUnit's assertFailure.

shouldBe :: (Show a, Eq a, MonadIO m) => a -> a -> m ()

actual `shouldBe` expected sets the expectation that actual is equal to expected (this is just an alias for @?=).

shouldSatisfy :: (Show a, MonadIO m) => a -> (a -> Bool) -> m ()

v `shouldSatisfy` p sets the expectation that p v is True.

shouldContain :: (Show a, Eq a, MonadIO m) => [a] -> [a] -> m ()

list `shouldContain` sublist sets the expectation that sublist is contained, wholly and intact, anywhere in the second.

shouldMatchList :: (Show a, Eq a, MonadIO m) => [a] -> [a] -> m ()

xs `shouldMatchList` ys sets the expectation that xs has the same elements that ys has, possibly in another order

shouldReturn :: (Show a, Eq a, MonadIO m) => m a -> a -> m ()

action `shouldReturn` expected sets the expectation that action returns expected.
