To associate defects with tests, you can perform the following actions:
A. Associate tests from the Test Plan module with defects: This option is correct. In the Test Plan module, you can associate tests with defects by linking them together. This helps to track the defects associated with specific tests.
B. Associate test sets from the Test Lab module with defects: This option is not correct. In the Test Lab module, you cannot directly associate test sets with defects. Test sets are collections of tests that are executed together, and they do not have a direct relationship with defects.
C. Associate defects with tests run during a manual test run: This option is correct. During a manual test run, if a defect is identified, you can associate it with the specific test run. This allows you to track the defects found during the execution of the test cases.
D. Associate tests with multiple defects: This option is correct. A single test can be associated with multiple defects. This is useful when multiple defects are identified during the execution of a single test case.
Therefore, the correct answers are A, C, and D. These options allow you to associate tests with defects and track the relationship between them.
