Which component is NOT typically a function of a test execution tool?

In the context of test execution tools, writing test cases is generally not a primary function of these tools. Test execution tools are designed primarily for executing tests that have already been created and for managing the results of those executions.

The primary functions of test execution tools include running automated tests, which allows for efficient and consistent testing of software; recording test results, which captures the outcomes of executed tests for analysis and reporting; and logging defects, which refers to the process of documenting issues found during testing for further investigation and resolution.

Writing test cases, on the other hand, is typically a function associated with test management tools or test design tools. These tools focus on the initial creation and organization of test cases based on requirements, specifications, and various testing strategies. Thus, while test execution tools may interface with test cases, their core capabilities center around executing those tests and managing the results rather than creating them from scratch.
