class SimpleTestExampleMockModuleTest

Demonstrate SimpleTest with a mock module.

SimpleTestExampleMockModuleTestCase allows us to demonstrate how you can use a mock module to aid in functional testing in Drupal.

If you have some functionality that's not intrinsic to the code under test, you can add a special mock module that only gets installed during test time. This allows you to implement APIs created by your module, or otherwise exercise the code in question.

This test case class is very similar to SimpleTestExampleTestCase. The main difference is that we enable the testing_example_test module by providing it in the $modules property. Then we can test for behaviors provided by that module.
