TestNG – Next Generation Testing Framework

by seetaram on January 8, 2012

TestNG is a testing framework that is used for unit testing and also with Selenium for Test Automation.

What is the need for a testing framework?

How it facilitates unit / automated UI testing?

What are the functionalities that a framework like JUnit / TestNG provides?

If I am new to Selenium, TestNG / JUnit, above questions will definitely popup in my mind. Let us have a close look at each one of them.

Need for a Testing Framework:

A Testing Framework helps in creation and execution of a group of tests. If there is no framework is used, then we only have to handle many things such as reporting, exception handling, grouping, data parameterization, etc.

How it facilitates?

A testing framework such as TestNG provides many annotations which can be utilized for certain functionalities. If we use @Test before a Java method then that method will be considered as a test method. We can individually execute the method with this annotation or execute with a suite of tests.  Also, the framework provides annotations for grouping, parameterizing, executing a particular Java method before or after the execution of a test method, etc.


  1. Annotations (@Test, @BeforeClass, etc)
  2. Supports data-driven testing
  3. Supports running tests in multiple threads

Nice intro to TestNG. Keep sharing such stuff.

Another great feature of TestNG is it supports parallel execution. This makes our tests scalable and saves much of tester’s time and efforts.
