Taking its cues from Junit, NetBeans and NUnit, TestNG is a free testing framework that provides more flexibility than the aforementioned testing tools. TestNG is also more powerful, and it’s easier to use than many of the alternatives. Although programs such as Junit and TestNG operate in the same sphere, they’re not direct competitors because each of them has valuable features that the others don’t.
The ‘NG’ in the name stands for ‘new generation’. It’s designed to cover all types of tests, including integration, end to end and functional. TestNG is supported by a variety of plug-ins, including NetBeans, IntelliJ IDEA and Eclipse.
What are the requirements for TestNG?
The first requirement for being able to use TestNG is having the JDK (Java Development Kit) installed on your Windows, Linux or Mac device.
You’ll also need to ensure that you have Java installed and then set up the Java environment on your computer.
How do I know if TestNG is installed?
After downloading the TestNG Archive, setting the TestNG Environment, and setting the CLASSPATH variable, you need to test the TestNG setup by creating a Java class file. If the test output shows one test run with no failures or skips, you’ve successfully installed TestNG.
What is TestNG in Selenium?
Using TestNG in Selenium lets you get a far more detailed look at test results than a default Selenium test. For example, if you run five tests and one of them fails, you can easily identify the failed test. Furthermore, having discovered which test failed, you can run it in isolation to test your ongoing fixes.
Easy use for programmers
Although it’s not a consumer-facing utility, TestNG still makes life easier and more productive for programmers. Making it easier to understand annotations and the ability to run your TestNG tests individually are enormous benefits for developers.
In our view, TestNG succeeds in making a technical process simpler for its users without oversimplifying and sacrificing functionality. It gives you greater control and more detailed information about failed tests.
