In further sections of this ‘How to group test cases in TestNG’ tutorial, we would demonstrate parallel testing in TestNG and Selenium using Test Groups. As seen in the execution snapshot, two test methods under the TestNG tag – “Search” are running in Parallel: Shown below are the execution snapshots from the IDE and the Automation Dashboard from LambdaTest it indicates that their tests were executed successfully: TestNG lets you run test methods that belong to multiple groups.

As seen in the testng.xml, tests under the groups – “Search” will be executed. For demonstrating the usage of regular expressions with TestNG groups, we run test methods that include the term “Search”. Shown below are the code modifications for creating four TestNg groups: A new group named “Group1” includes the test methods implemented under the “Search1” and “Search2” groups. Here is the overall project structure which we created in IntelliJ IDEA IDE: In the TestNGGroups project, we create a package named org.testnggroup, where we create the following class files (that contain the implementation of the relevant test scenarios): (Implementation of Test Scenarios in ‘Test Group 1’), (Implementation of Test Scenarios in ‘Test Group 2’), (Implementation of Helper Functions for creating an instance of RemoteWebDriver).
