The Specifics of TestNG

While performing different types of software testing, the specialists can use particular testing tools and frameworks. For example, for executing automated testing, TestNG can be applied. This tool was created by Cedric Beust. It is an open-source automation framework.

The abbreviation NG in its name means Next Generation. The point is that TestNG, JUnit and NUnit have some common features. But TestNG has a higher level of usability and possesses wide capacities. And ‘NG’ symbolizes the updated version of all previous tools.

What Are the Key Feature of TestNG?

  • Annotation support
  • Support of integrated class testing
  • Flexible configuration of run-time
  • Test groups implementation
  • Support of load testing, dependent test methods, parallel testing
  • Flexible API plug-in
  • Support of multithread testing.

With the help of TestNG, the specialists can cover all test categories: unit and functional tests, integration test scripts, end-to-end tests, etc. But the tool requires JDK 5 and higher versions. TestNG makes the process of data parametrization available. Besides that, the tool ensures the simple and fast procedure of test case creation.

What Are the Steps of Creating TestNG Cases?

  1. The creation of business logic of the tests.
  2. The implementation of TestNG annotations.
  3. The description of tests, including its calls, group, names of methods, etc.
  4. TestNG launching.

At step two, the specialists can add different additional parameters of the annotations. As they are strictly typed, the compiler will immediately detect any error. TestNG provides the option of creating HTML reports and it generates logs.
