What is a "test execution log"?

A test execution log serves as a comprehensive record of all tests that have been executed during the testing process, capturing crucial information about the outcomes and details of each test case executed. This log typically includes the test case identifiers, the results (e.g., pass or fail), timestamps of execution, and any relevant comments or observations made during the testing.

The primary purpose of this log is to provide transparency and traceability regarding testing activities. It allows teams to track which tests have been run, identify patterns in failures, and provide data for analyzing the quality of the software being tested. By maintaining this log, QA teams can ensure an organized approach to testing, making it easier to report on quality metrics and improve the testing process over time.

In contrast, the other options focus on different aspects of the testing process, such as summaries of test case creations, overall software development lifecycle documentation, or the specific setup of test environments, which do not provide the detailed, execution-focused information that a test execution log is intended to convey.
