How To Group Test Cases In TestNG

QAutomation News / By  Himanshu Sheth

TestNG is an open-source automation testing framework inspired by JUnit and NUnit. The framework supports data-driven testing, parallel test execution, testing integrated classes, provides access to HTML reports, amongst others. TestNG can be seamlessly integrated with Jenkins, Eclipse, IntelliJ IDEA, Maven, etc.

Annotations in TestNG are useful for controlling the test methods’ execution flow and running multiple tests in Parallel. Parameterized TestNG tests with Selenium WebDriver are handy for running test(s) against different browser and platform combinations. As a part of our TestNG tutorial series, we look at how to group test cases in TestNG. The usage of groups in TestNG is demonstrated with relevant TestNG group examples.

What Are TestNG Groups?

As the name indicates, grouping in TestNG lets you group multiple test methods in named groups. Through groups in TestNG, you have the provision to run a particular set of tests that belong to a group or multiple groups.

Consider a scenario where the test suite comprises different test types, e.g., unit test, integration test, smoke test, etc. Instead of adding all the test scenarios in a single test suite (or multiple test suites), you can perform ‘grouping’ test methods. This helps in segregating the test scenarios into different test categories – test type (e.g., smoke, functional, etc.), functionality being tested (login, checkout, etc.), and test combinations (e.g., browser set to Chrome, Firefox on Windows 10, etc.).
