TestNG

TestNG is a testing framework for the Java programming language created by Cedric_Beust and inspired by JUnit and NUnit. The design goal of TestNG is to cover a wider range of test categories: unit, functional, end-to-end, integration, etc., with more powerful and easy-to-use functionalities.

• TestNG is a very important framework when you are actually developing the framework from scratch level.
• TestNG provides you full control over the test cases and the execution of the test cases. Due to this reason, TestNG is also known as a testing framework.
• Cedric Beust is the developer of a TestNG framework.
• If you want to run a test case A before that as a pre-request, you need to run multiple test cases before you begin a test case A. You can set and map with the help of TestNG so that pre-request test cases run first and then only it will trigger a test case A. In such way, you can control the test cases.
• TestNG framework came after Junit, and TestNG framework adds more powerful functionality and easier to use.
• It is an open source automated TestNG framework. In TestNG, NG stands for "Next Generation".
• TestNG framework eliminates the limitations of the older framework by providing more powerful and flexible test cases with help of easy annotations, grouping, sequencing and parametrizing.

Advantages of TestNG over Junit

Use of TestNG

TestNG is a powerful testing framework that offers several advantages over other frameworks, such as JUnit and NUnit. Some of the key benefits of TestNG include:

Automation TestNG with Selenium

Let's understand automation through this TestNG framework tutorial. TestNG being 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.

Dive into the practical demonstration of automation using TestNG. We will cover the installation process using 2 of the most used IDEs Eclipse and IntelliJ.

To understand the automation process better we have stressed on annotations and attributes. Annotations are used to provide meaning to any function in the test script and describe its behavior. Attributes are part of annotations that help in making our tests more defined.
