Which is not a major task of test implementation and execution?

The task identified as not a major part of test implementation and execution pertains to the logging of outcomes alongside recording identities and versions of the software being tested. While this is an important aspect of the overall testing process, it primarily relates to the documentation and tracking of test results, which is more aligned with the activities following test execution rather than the execution itself.

Test implementation and execution primarily focus on the preparation, actual conduct of tests, and immediate outcomes. This encompasses developing test cases that are prioritized based on risk and importance, creating the necessary data to execute tests effectively, and writing procedures that guide how tests should be performed. Additionally, confirming that the test environment is configured properly is vital to ensure that tests yield reliable results.

In summary, while logging outcomes and recording software versions is essential, it does not directly involve executing tests or implementing the test strategies, which is why it is categorized differently in the overall testing process.
