Following are the key features of Selenium TestNG: There are so many features of TestNG, but we will only focus on the most important ones that we can use in Selenium. Most Selenium users use this more than Junit because of its advantages. Using TestNG in Selenium, we can generate test results.

Coding of our First TestNG Test Case Exampleĭefault Selenium tests do not generate a proper format for the test results.

Create Test Case Using TestNG Annotations.

It will execute only failed test cases.īeside above concept, you will learn more on TestNG, like what are the Advantages of TestNG, how to create test methods using annotations, how to convert these classes into testing suite file and execute through the eclipse as well as from the command line. If you want to run only failed test cases means you run this XML file.

The TestNG in Selenium provides an option, i.e., testng-failed.xml file in test-output folder.

This is not possible without using TestNG. Then correct the errors present in the fourth method, now you want to run only fourth method because first three methods are anyway executed successfully.

When you run this program first, three methods are executed successfully, and the fourth method is failed. Suppose, you have five test cases, one method is written for each test case (Assume that the program is written using the main method without using testNG).You can execute the failed test cases separately.

Using TestNG, you can generate a proper report, and you can easily come to know how many test cases are passed, failed, and skipped. TestNG is inspired by JUnit which uses the annotations TestNG overcomes the disadvantages of JUnit and is designed to make end-to-end testing easy. TestNG is an automation testing framework in which NG stands for “Next Generation”.
