TestNG

In order to better plan and carry out your Selenium tests, TestNG offers sophisticated capabilities like annotations, data-driven evaluation, test sequencing, and parallel testing.

TestNG will execute simultaneously in a maximum of 5 threads.

We have the ability to run test cases according to the group with Selenium's TestNG. Consider a situation in which you have established the groups "Regression" and "Sanity." The TestNG framework makes it simple to execute the test cases listed under the Sanity group.

TestNG is extensively used with Java and is widely regarded as one of the top testing frameworks for Java applications. Originally developed for Java, TestNG has gained popularity for its robust features and capabilities. Although it was specifically designed with Java in mind, developers have created integrations and plugins that enable TestNG to work seamlessly with other programming languages like Kotlin and Groovy.

TestNG offers parallel test method execution. It enables the definition of one test method's dependence on another method. And it also enables you to give test methods higher priority.

 The testing framework is called TestNG (Test Next Generation). Although it draws inspiration from JUnit and NUnit, TestNG includes additional features which render this framework more effective and simple. All test types, including unit, functional, and integration tests, are included in the design of TestNG.

In TestNG, there are several annotations that serve specific purposes during test execution:

1. @BeforeMethod: This annotation indicates a method that will run before each test method. It allows you to set up any preconditions or initialization required for the individual test methods.

2. @AfterMethod: This annotation designates a method that will execute after each test method is run. It is helpful for performing cleanup or teardown actions after each test completes.

3. @BeforeGroups: When you use the @BeforeGroups annotation, the associated method will run before the test cases belonging to a particular group are executed. It executes only once, preparing the environment for the group of tests.

TestNG is a Java-based framework that offers an efficient way to run tests.
