Which TWO tools are classified as test execution tools?

The identification of test execution tools focuses on those that facilitate the execution of tests and the evaluation of the results. Test comparators serve this purpose by allowing testers to automate and verify the outcome of tests against expected results, often used in regression testing or when comparing actual outputs to expected ones to identify discrepancies.

On the other hand, the recognition of test harness as an additional correct answer lies in its role in orchestrating the execution of test scripts. A test harness provides the necessary environment and infrastructure for running tests, including setup, execution, and teardown phases. It can automate the invocation of the test cases, manage test execution, and gather test results, making it a crucial component in the test execution process.

In contrast, test data preparation tools focus on generating or manipulating data needed for testing but do not directly execute tests. Review tools are utilized for assessing work products and verifying that quality criteria have been met, while they are valuable in the overall testing process, they do not play a direct role in executing test cases.
