+The helper method `shouldExpect` is the same as `shouldRun` but adds the expection that `handle` will be called once and only once.

+```php
+FetchContactsFromGoogle::shouldExpect();

 ## Partial mocking
 
 If you only want to mock the methods that have expectations, you may use the `partialMock` method instead. In the example below, only the `fetch` method will be mocked.
