Which testing framework do you prefer with Selenium TestNG, JUnit, or PyTest and why?

I prefer using TestNG with Selenium due to its powerful features like parallel test execution, detailed reporting, and flexible test configuration. It integrates smoothly with build tools like Maven and CI/CD pipelines, making automation more efficient. While JUnit is great for Java-based projects and PyTest for Python, TestNG offers more advanced annotations and test management capabilities. During Testing online training, learners often find TestNG easier to adopt for real-world scenarios, especially in enterprise-level applications. Its ability to group, prioritize, and parameterize tests makes it a preferred choice for testers aiming to scale and maintain robust automation frameworks.
