Which of the following is not true of regression testing?

The assertion that regression testing serves to demonstrate that the changed software works as intended does not accurately reflect the primary objective of regression testing. Regression testing is primarily concerned with verifying that any modifications or updates made to the software, such as enhancements or bug fixes, have not adversely affected the existing functionality. While it may indirectly provide some evidence that the changed software behaves as expected through successful test outcomes, the core intention is to ensure that previously functioning features remain intact and unaffected by the new changes.

In contrast, regression testing can indeed be conducted at each stage of the software development life cycle, it performs the crucial function of confirming that no unintended changes have occurred in the software as a result of modifications, and it is frequently automated to enhance efficiency and repeatability in test execution.
