TestNG

TestNG is a testing framework for Java applications that is similar to JUnit, but provides additional features and functionality. TestNG provides a way to write and run automated tests, but also includes features such as data-driven testing, parallel test execution, and flexible test configuration. TestNG is designed to be more flexible and powerful than JUnit, making it a popular choice for Java developers who need to test complex and large applications.
