Consider A TAS for testing a desktop application via its GUI.

The best recommendation for improving the Test Automation System (TAS) in this scenario is to implement standard setup and teardown functions at the test case level. This approach promotes reusability and efficiency by allowing the same initial and final sequences of steps to be used across multiple test cases. By centralizing these sequences into common functions, any changes to the setup or teardown process only need to be made in one place, thus reducing maintenance efforts and potential for errors. Furthermore, it streamlines the execution of test cases and makes the automation framework more robust and easier to manage.
