This topic provides an overview of the different ways that you can extend and modify the automatically generated unit test suite.
Use the following table as a reference to determine which test suite extension/modification methods are best suited to your goals
| To achieve this | Do this | Reference |
|---|---|---|
| Add new test cases to check specific unit-level functionality requirements or to improve coverage | Use the Test Case Editor or Test Case Wizard to create test cases graphically, or add code to test case templates | Adding User-Defined Test Cases |
| Modify automatically-generated test cases to check specific unit-level functionality requirements or to improve coverage | Edit the related test files | Adding User-Defined Test Cases |
| Modify test generation or execution settings | Configure settings in the Test Configuration panel’s Generation and Execution tabs | Generation Tab Settings: Defining How Test Cases are Generated and Execution Tab Settings - Defining How Tests are Executed |
| Remove test cases and disable outcome checks or test cases that are not currently of concern to you | To remove a test suite: Right-click its Test Case Explorer node and choose Delete To remove a test case: Right-click its Test Case Explorer node and choose Delete To disable checking of a specific outcome: Right-click the unverified outcome in the Quality Tasks view, then choose Ignore Outcome from the shortcut menu To disable a complete test case: Right-click its Test Case Explorer node and choose Disable | Deleting and Disabling Tests |
| Prevent the testing of certain classes or methods | Specify the resources that you want to include or exclude | Testing a User-Defined Set of Resources |
| Convert automatically generated tests into a "functional snapshot" for regression testing (to identify changes/problems introduce by code modifications) | If the code is behaving correctly, right-click the unverified outcome node, then choose Verify Outcome from the shortcut menu | Verifying Test Cases for Regression Testing |
| Access data source values during testing | Configure test cases to access values stored in a data source. | Using Data From Data Sources to Parameterize Test Cases |
| Use standard I/O data in test cases | Add C++test Stream API calls for redirecting standard input/output stream | Using Data From Standard IO |
| Define custom stubs (to specify what values an external method/function returns to the class under test) | Use the Stub wizard to create a stubs framework, then customize it. | Adding and Modifying Stubs |
| Execute existing unit test cases (i.e., CppUnit test cases) using C++test | Ensure that your preferred test execution Test Configuration can find the test cases | Executing Manually-Written CppUnit Test Cases |
