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.

Choosing The Right Selenium TestNG Framework

New generation frameworks are emerging today with multiple advantages that can mark a shift in how applications are created and used. Of course, the best framework depends on you, your team, and the goals you're trying to hit. But no matter what you choose, TestNG can test anything quickly and easily.

So check out this article to know why you should choose TestNG as a framework.

A Complete Guide for Your First TestNG Automation Script

Automation testers are drawn to TestNG, a Java testing framework that can be used to drive Selenium Automation. When it comes to automation, no one can compete with Selenium. However, it can be challenging for a beginner to find the starting point for learning. This chapter will act as your step-by-step guide.


Running Tests with TestNG

This section of the Selenium TestNG tutorial will act as your step-by-step guide to successfully running tests with TestNG.

How to Automate using TestNG in Selenium?

Java's TestNG framework is a popular option for automation engineers, who can rely on its in-built features and know that they have an active community of developers behind their back. This chapter teaches you how to install TestNG and use it to run your first Selenium test script with TestNG.


How to Perform Parallel Test Execution in TestNG with Selenium

The traditional approach of manual testing is already overtaken by automation testing. One widely adopted automation testing strategy is the shift from sequential testing to parallel testing. This chapter takes you through the steps of performing parallel test execution in TestNG.


Creating TestNG XML File & Execute Parallel Testing

If you are looking to make the most out of a Selenium Grid, then executing multiple test files at once is the way to go. In this tutorial, we will show you how to run multiple tests from a TestNG XML file.


Speed Up Automated Parallel Testing in Selenium with TestNG

Manual testing of an application on multiple browsers can be time-consuming and stressful. Imagine the amount of time required to perform manual testing on multiple browsers. With automated cross-browser testing, you need not spend much time and energy on compatibility issues. This chapter will teach you how to speed up your automated parallel testing with TestNG.


Automation Testing With Selenium, Cucumber & TestNG

Ready to run your first Cucumber script and leverage TestNG capabilities to perform parallel testing? Check out our guide on Automation Testing With Selenium, Cucumber & TestNG.


How to Run JUnit Selenium Tests using TestNG

If you've learned both the JUnit and TestNG test frameworks, you may be able to run JUnit-based tests using the TestNG framework. In addition, the TestNG framework supports tests in more categories than JUnit, making it easier to migrate test cases from JUnit to TestNG. In this chapter, we look at how you can write test cases with JUnit and TestNG without re-writing tests.


Deep diving into Advanced Use Cases for Selenium TestNG

In this section of the Selenium TestNG tutorial, you will learn more about the TestNG testing frameworks by deep diving into the use cases for Selenium TestNG.

How to Group Test Cases in TestNG [With Examples]

TestNG lets you group test methods in named groups. Using groups, you can run a set of tests that belong to a group or multiple groups. In this chapter, we’ll take a look at how to group test cases in TestNG.


How to Set Test Case Priority in TestNG with Selenium

TestNG allows you to set priority for test cases as well as run them in the order you want. This is especially useful when defining a sequence for the test case execution or when assigning precedence to some methods over others. Learn more about this by checking out this chapter.


How to Use Assertions in TestNG with Selenium

When a failure of the test is encountered, TestNG halts execution. Therefore, programmers use TestNG's assertion mechanisms to run certain actions when they encounter problems while performing automated Selenium WebDriver testing. Check out this chapter to learn how you can make use of them.


How to Use DataProviders in TestNG [With Examples]

DataProvider in TestNG allows us to pass multiple parameters to a single test using only one execution cycle. This can be helpful when we need to pass multiple values to a test in just one execution cycle. This chapter will teach you how to use DataProviders in TestNG.


Parameterization in TestNG - DataProvider and TestNG XML [With Examples]

If most of your tests are likely to have similar actions, then Parameterization may be the right tool for you. We can use Parameterization in our automation scripts, depending on the framework we're using. Check out this detailed chapter on Parameterization in TestNG.


TestNG Listeners in Selenium WebDriver [With Examples]

TestNG Listeners allow you to customize test results and provide valuable information on your tests. Selenium WebDriver's TestNG Listeners are modules that listen to certain events and keep track of the test execution while performing some action at every stage of test execution.


TestNG Annotations Tutorial with Examples for Selenium Automation

Annotations were first added to the Java language in JDK 5. See this chapter in our TestNG tutorial for details about why you might use annotations and different attributes of TestNG that can help add structure to your code.


How to Use TestNG Reporter Log in Selenium

TestNG provides us with the Reporter Class, which allows us to create reports that are informative and helpful without relying on third-party software, improving efficiency and analysis of information. Check out this chapter to learn how you can use the TestNG Reporter Log.
