Description: Executing tests is the action of carrying out test cases designed to verify that the software behaves as expected. This process is fundamental in test-driven development (TDD), where tests are created before the code is written. By executing tests, developers can identify errors and unexpected behaviors in the software, ensuring that each component functions correctly and meets established requirements. Test execution is not limited to functionality verification; it also includes performance, security, and usability testing. This systematic approach allows development teams to maintain a high standard of quality in their products, facilitating early problem detection and reducing the cost of fixing errors in later stages of the software lifecycle. Additionally, test execution provides valuable documentation about the software’s behavior, which can be useful for future reference and maintenance. In summary, executing tests is an essential component of modern software development, ensuring that products are reliable and meet user expectations.
