Selenium TestNG Tutorial


TestNG is a Java-based open-source test automation framework. It covers a broader range of test categories: unit, functional, end-to-end, integration, etc. This framework is quite popular among developers and testers for test creation due to its useful features like grouping, dependence, prioritization, ease of using multiple annotations, etc. Another reason for its popularity is that it helps them organize tests in a structured way and enhances the scripts' maintainability and readability.

Though, it is developed on the same lines as NUnit and JUnit. But, its advanced features make it a much more robust framework in comparison to its peers.

How To Install TestNG?

As you already know, TestNG or Test Next Generation is one of the most frequently used automation testing frameworks in Java. Inspired by JUnit and NUnit, Cedric Beust created TestNG with the idea of covering almost all types of testing models, be it functional or end-to-end. Read more to learn the basics of installation and understand the environment setup in this TestNG tutorial.


Write Your First Test Using TestNG

In this chapter of TestNG tutorial, we will create a TestNG project from scratch and write our very first test script using TestNG. We will begin by setting up a TestNG project first and then move on to writing the scripts.


Run Tests In TestNG Using XML File

In this TestNG tutorial, let’s dive deep into how we can execute multiple test files from a single file known as the TestNG XML file. We will also see how we can create and execute a parallel testing suite using a TestNG XML file.


How To Use TestNG Annotations

Do you know that annotations were formally added to the Java language in JDK 5? Checkout this chapter in our TestNG tutorial, as we have explained different annotations and attributes of TestNG that help to provide better structuring and readability to the code.


Parameterization In TestNG

Parameterization in TestNG or any other framework is considered one of the best ways to run tests in parallel on multiple different test environments. In this TestNG tutorial, you will learn how to perform parameterization in TestNG for Selenium automation testing.


How To Use DataProvider?

Parameterization In TestNG helps us pass data through the code and prevent hard-coding. However, TestNG parameters enable us to pass the values only once per execution cycle. To overcome this, we can use DataProvider in TestNG that allows us to pass multiple parameters to a single test in a single execution. Read the blog to learn more on using DataProvider.


TestNG Listeners In Selenium WebDriver

There are different interfaces provided by Java that allow you to modify TestNG behavior. These interfaces are known as TestNG Listeners in Selenium WebDriver. In this chapter of TestNG tutorial learn more about TestNG Listeners and know what are the frequently used Listeners with examples.
