TestNG is a strong testing framework that is an improved version of JUnit, which has been in use for a long time before TestNG. The abbreviation NG stands for 'Next Generation.' Annotations make it easier to organise the tests. It is easier to group test scenarios.
Write your test's business logic and include TestNG annotations in your code.
In a testng. xml file or in build. xml, provide information about your test (e.g., the class name, the groups you want to execute, etc.).
TestNG should be run.
TestNG improves the structure, readability, maintainability, and user-friendliness of automated tests. It has a lot of functions and reports. Its high-end annotations, such as dataprovider, help you scale out your cross-browser testing across various devices, browsers, and versions.
