Azure provides documentation for unit testing HTTP and Queue Python functions. This is done by creating a mock QueueMessage or HTTPRequest. However, there is no documentation for creating a unit test for Timer functions.

There is a TimerRequest class, but creating a new instance of it fails with the following error:

req = func.TimerRequest()

TypeError: Can't instantiate abstract class TimerRequest with abstract methods past_due

Having posted on StackOverflow to ask about the correct approach for this e.g. if I want to test behaviour of a function which has past_due set, but had no answers, I'm opening this bug to request that Python functions allow unit testing.
