Adam Wathan:
Detecting Out of Sync Mocks in Mockery
Apr 05, 2017 @ 11:14:41

Adam Wathan has shared a new post on his site with advice on finding out-of-date mocks when using the Mockery mocking tool in your testing.

If you're not careful, it's easy to find yourself in a situation where a test double has gotten out of sync with the actual class or interface it's mocking.

In this quick screencast (taken from my Test-Driven Laravel course), I walk through how I use a little-known Mockery feature to help track down these issues and make sure I'm not mocking methods that don't exist.

The quick screencast (about 4 minutes) gives an example of locating the issue when a "Ticket" class is refactored. While the tests still pass, it can cause issues in testing and can be difficult to find. Mockery comes with a configuration option (in 1.0 alpha) to disable the mocking of methods that don't exist on the original object. He shows how to disable this feature and what the resulting error looks like when the tests are run.
