For Software Maintenance Support, automated testing frameworks like Selenium, Appium, and TestNG are well-suited for streamlining regression testing. Selenium offers robust web testing capabilities, allowing testers to automate browser interactions across different platforms. Appium specializes in mobile application testing, supporting both Android and iOS platforms. TestNG provides a comprehensive testing framework for Java applications, enabling testers to create and manage test cases efficiently. These frameworks help ensure that changes made during software maintenance do not introduce regressions, allowing teams to validate the system's functionality quickly and reliably, ultimately enhancing the software's overall quality and stability.
