Introduction

Testing is an integral part of software development. It helps to ensure that the software is of high quality and works as expected. Selenium is a popular open-source tool used for automating web applications. TestNG is an open-source testing framework that is used in conjunction with Selenium to perform automated testing. In this article, we will discuss what TestNG is and how it is used in Selenium.

What is TestNG?

TestNG stands for “Next Generation” and is an open-source testing framework. It is designed to simplify a broad range of testing needs, from unit testing to integrated system testing. TestNG is a testing framework inspired by JUnit and NUnit. It is designed to cover all categories of tests: unit, functional, end-to-end, integration, etc.

TestNG provides various features that make it more powerful and easier to use than other testing frameworks. These features include annotations, parameterized tests, execution reports, and more. It also supports data-driven testing, which allows you to run the same test multiple times with different data sets.

How TestNG Works

TestNG works by creating test suites, which are collections of tests. Each test suite consists of one or more test cases. A test case is a set of instructions that are executed to verify the functionality of a feature or application. TestNG provides various annotations that are used to define the test cases.

TestNG also provides a test runner, which is a program that executes the test cases. The test runner reads the test suite and executes the test cases. It also generates reports that show the results of the tests.

Benefits of TestNG

TestNG provides various benefits that make it a popular choice for automated testing. These benefits include:

• Flexibility: TestNG is highly flexible and can be used for both unit and integration testing. It also supports data-driven testing, which allows you to run the same test multiple times with different data sets.

• Annotation Support: TestNG provides various annotations that are used to define the test cases. This makes it easier to write and maintain test cases.

• Execution Reports: TestNG generates execution reports that show the results of the tests. This makes it easier to identify and fix errors.

• Parameterized Tests: TestNG supports parameterized tests, which allow you to run the same test multiple times with different data sets.

• Assertions: TestNG provides various assertions that can be used to verify the expected results of a test.

How TestNG is Used in Selenium

Selenium is a popular open-source tool used for automating web applications. It is used to automate the process of testing web applications. TestNG is used in conjunction with Selenium to perform automated testing.
