TestNG tutorial

TestNG is a Java-based open-source framework for test automation that includes various test types, such as unit testing, functional testing, E2E testing, etc. TestNG is in many ways similar to JUnit and NUnit. But in contrast to its competitors, its extensive features make it a lot more reliable framework. One of the major reasons for its popularity is its ability to structure tests and improve the scripts' readability and maintainability. Another reason can be the important characteristics like the convenience of using multiple annotations, reliance, and priority that make this framework popular among developers and testers for test design. You can refer to the TestNG tutorial to learn why you should choose the TestNG framework.
