Recent Changes

equivalent." |

| Hard-Coded Test Double | Category: Test Double Patterns | 18 February 2007 |

calls. |
||
| Test Spy | Category: Test Double Patterns | 4 February 2007 |
| Use a Test Double to capture the indirect output calls made to
another component by the SUT for later verification by the test. |
||
| Test-Specific Subclass | Category: Test Double Patterns | 4 February 2007 |
| Add methods that expose the state or behavior needed by the test to a
subclass of the SUT. |
||
| Mock Object | Category: Test Double Patterns | 6 November 2006 |
| Replace an object the system under test (SUT) depends on with a test-specific
object that verifies it is being used correctly by the SUT. |
||
| Configurable Test Double | Category: Test Double Patterns | 6 November 2006 |
| Configure a reusable Test Double with the values to be returned or verified
during the fixture setup phase of a test. |

| We replace a real object with a test-specific object that feeds the desired
indirect inputs into the system under test. |
