Test.HMock.MockMethod

Functions to delegate Actions to HMock to match expectations. There is one delegation function that works if the return type has a Default instance, and another that doesn't require the Default instance, but causes the method to return undefined by default.

mockMethod :: (HasCallStack, MonadIO m, MockableMethod cls name m r, Default r) => Action cls name m r -> MockT m r

Implements a method in a Mockable monad by delegating to the mock framework. If the method is called unexpectedly, an exception will be thrown. However, an expected invocation without a specified response will return the default value.

mockDefaultlessMethod :: (HasCallStack, MonadIO m, MockableMethod cls name m r) => Action cls name m r -> MockT m r

Implements a method in a Mockable monad by delegating to the mock framework. If the method is called unexpectedly, an exception will be thrown. However, an expected invocation without a specified response will return undefined. This can be used in place of mockMethod when the return type has no default.
