Modules larger than a single function or class introduce new difficulties in testing. In this module, you will learn:

• When and why you might introduce a test double in your testing
• How and when to apply different kinds of test doubles such as mocks and spies
• Why a system might require tests larger than unit tests.

Lecture Slides:

• Testing Effectful Code Slides PDF, PPT
• Beyond Unit Testing Slides PDF, PPT
