TestNG Tutorial With Selenium | How To Do Parallel Testing In TestNG 📃| Part-IX | LambdaTest

About The Video

In this ninth video of the TestNG tutorial for beginners series, Rex Jones (@RexJonesII), a seasoned QA Engineer, Trainer, YouTuber, and Blogger, deep dives into the integral aspects of parallel testing in the TestNG framework. He also explains how the testng.xml file has a parallel attribute for parallel testing that we can set to classes, methods, and tests. He then shows how to use threadpoolsize and invocationcount test attributes. In the end, he talks about what is required to do data-driven testing in TestNG.

Key Topics Covered

Parallel Testing: It explains the concept of executing multiple test scripts simultaneously to save time and increase efficiency. The video details how to set up automation code for running tests across different browsers, operating systems, and devices. It introduces the parallel attribute in the TestNG XML file, which can be set to classes, methods, or tests to determine how tests execute in parallel. Additionally, it discusses the use of thread pool size and invocation counter attributes for effective parallel testing.

Data Providers for Data Driven Testing: The video describes how to use data providers in TestNG to perform data-driven testing, allowing the input of various data sets into test scripts. It demonstrates how to create a data provider annotation, how to send data from the same or a different class using the data provider class attribute, and how to apply these concepts in a practical example involving a web application.

Practical Demonstration: Throughout the video, there are practical demonstrations of setting up tests in IntelliJ IDEA, including writing WebDriver code for Selenium tests, configuring TestNG XML for parallel execution, and applying data-driven testing techniques. The examples include working with web elements, setting up before and after methods, and executing tests on a Selenium playground website.
