What is a Java tester?

A Java Tester is a software professional responsible for testing Java-based applications to ensure they function correctly, meet requirements, and are free of defects. They design and execute test cases, identify bugs, and work with developers to resolve issues. Java Testers use testing frameworks like JUnit, Selenium, and TestNG to automate and perform manual testing. Their role ensures the overall quality, performance, and reliability of Java applications before deployment.
