Using TestNG, we can also execute failed test cases separately.įor example, suppose, we have 5 test cases, and out of five test cases, the first three test cases are successfully executed but the fourth test case is failed due to some error. So, we can easily execute 5 test cases using TestNG framework.ģ. We can execute selective test cases by integrating TestNG with Selenium WebDriver.įor example, suppose, we have 25 test cases and we want to execute only 5 test cases. We can easily generate detailed test reports or test result in a proper readable format (or in an organized folder) to know about how many test cases are passed, failed, and skipped.Ģ. If Selenium test cases are created by integrating TestNG with Selenium WebDriver, no external task is required to generate detailed test reports. Selenium WebDriver does not generate detailed test or summary reports. There are the following reasons or purposes for using TestNG with Selenium.
Why do we use TestNG Framework with Selenium? It can be used for unit, integration, functional and end-to-end testing. Therefore, TestNG has gained a lot of popularity in a very short time which is widely used nowadays as an automation testing framework with Selenium WebDriver. It is distributed under the Apache Software License and is readily available for download. It mainly uses Java annotations to configure and write test methods. TestNG was developed by Cedric Beust to overcome the deficiency in JUnit by introducing some more new functionalities and features. Creating data-driven tests in TestNG is very easy as compared with JUnit. TestNG provides a DataProvider feature to perform data-driven testing. It provides multiple rich features for testing like assertions, reporting, parameterization, parallel test execution, etc. It is a widely used unit testing and reporting framework with Selenium WebDriver. TestNG is an advanced framework that can be integrated with Selenium or any other automation tool. TestNG, where NG stands for “Next Generation” is the next step towards writing test cases. It is an open-source automation testing framework based on JUnit (in Java) and NUnit (in C#).
