What is software test automation?

Software test automation refers to the use of specialized tools and scripts to automatically execute tests on software applications, reducing the need for manual testing. This approach increases testing efficiency, improves accuracy, and enables frequent regression testing throughout the development lifecycle. Test automation is especially valuable in agile and continuous integration/continuous deployment (CI/CD) environments, where rapid and repeated testing is essential. Common tools include Selenium, Appium, and JUnit, among others.
