Which TWO tools are classified as test execution tools?

Test execution tools are designed to facilitate the actual running of tests as part of the testing process. Among the options listed, test comparators and test harnesses fall into the category of tools that are specifically used during the test execution phase.

Test comparators are essential for comparing the actual output of tests against expected results, which is fundamental in evaluating whether the software behaves as intended. They help automate the comparison process, making it easier to determine discrepancies and ensuring thorough validation of the system under test.

A test harness, on the other hand, provides an environment for executing tests, managing the inputs to the tests, and capturing the outputs for further analysis. It enables testers to run their test cases in a controlled manner, validating the functionality of the software.

In contrast, test data preparation tools are primarily focused on generating or managing the data required for testing, while review tools are used for inspecting and assessing artifacts like requirements or design documents, rather than executing tests.
