What is automation testing in QA?

H2K Infosys automation testing in QA refers to the process of using specialized tools and scripts to execute test cases automatically, without human intervention. It helps ensure software quality by validating functionality, performance, and reliability more efficiently than manual testing. Automation testing is especially useful for repetitive tasks, regression testing, and large-scale projects. By reducing human error and speeding up execution, it improves the accuracy and consistency of results. Common tools include Selenium, TestNG, and JUnit. Overall, automation testing enhances productivity, saves time, and supports continuous integration and delivery in modern software development environments.
