Transcripted Summary
In this chapter we will look at how to execute parallel tests from Jenkins.
Let's have a look at our project which contains two suites, "suite1" and "suite2".
Each suite implements a single class containing two tests. "OpenCartTest.java" and "SourceDemoTests.java" are the source files.
Class "OpenCartTest" contains two methods. launchSite() launches a URL and verifies the header. searchForProduct() searches for a product on the OpenCart website.
Similarly, class "SourceDemoTests" contains two test methods. open() launches a URL and verifies the header. login() tests a login action and verifies whether or not users can see products.
If we wish to execute these in parallel we know that TestNG manages multiple suite execution through "testng.xml".
We have completed this configuration to run these suites in parallel. There is nothing else we need to do from Jenkins as we have already configured this behavior through TestNG.
Let us see how it gets executed in Jenkins.
In Jenkins I'm triggering the build of our project. We have already configured Jenkins to checkout from Git so it pulls the latest changes and begins execution.
Here we see it launching two browsers and both of the test cases will execute in parallel. All good. So the execution is done.
The source code for the test classes as well as the "testng.xml" configuration are included below.
