a package:persistent-test

Same as askUnliftIO, but returns a monomorphic function instead of a polymorphic newtype wrapper. If you only need to apply the transformation on one concrete type, this function can be more convenient.

askUnliftIO :: MonadUnliftIO m => m (UnliftIO m)

persistent-test Init

Capture the current monadic context, providing the ability to run monadic actions in IO. See UnliftIO for an explanation of why we need a helper datatype here. Prior to version 0.2.0.0 of this library, this was a method in the MonadUnliftIO type class. It was moved out due to https://github.com/fpco/unliftio/issues/55.

assertBool :: HasCallStack => String -> Bool -> Assertion

persistent-test Init

Asserts that the specified condition holds.

assertEmpty :: MonadIO m => [a] -> m ()

persistent-test Init

assertFailure :: HasCallStack => String -> IO a

persistent-test Init

Unconditionally signals that a failure has occurred.

assertNotEmpty :: MonadIO m => [a] -> m ()

persistent-test Init

assertNotEqual :: (Eq a, Show a, HasCallStack) => String -> a -> a -> Assertion

persistent-test Init
