What is TestNG? Why do we need TestNG in Selenium?

TestNG makes automated tests more structured, readable, maintainable, and user-friendly. It provides powerful features and reporting. Its high-end annotations like dataprovider, make it easier to scale up, as you perform cross browser testing across multiple devices, browsers, and their versions.

TestNG is an open-source testing framework for Java that is widely used in the software industry for testing Java-based applications. TestNG stands for Test Next Generation, which means it provides an advanced and better version of JUnit, another popular testing framework.

TestNG offers a wide range of features such as annotations, grouping, sequencing, parallel execution, reporting, and more, which makes it more powerful and flexible compared to other testing frameworks. With TestNG, testers can easily manage and execute tests, generate reports, and perform data-driven testing, among other functionalities.

When it comes to Selenium, TestNG is particularly useful because it provides integration with Selenium WebDriver, which allows testers to automate web application testing more effectively. TestNG can help testers to organize their Selenium test scripts, execute them in a specific order, run tests in parallel, and generate reports to analyze test results.

TestNG provides various annotations such as @BeforeTest, @AfterTest, @BeforeSuite, @AfterSuite, and more, which can be used to perform pre-test and post-test activities, set up the environment, and tear down the environment. It also provides various assertions to validate test results and allows testers to configure test runs with different parameters.

Overall, TestNG is a powerful and flexible testing framework that makes testing Java-based applications, including Selenium test scripts, more efficient and manageable.
