TestNG tutorial

TestNG is a Java-based open-source framework for test automation that includes various test types, such as unit testing, functional testing, E2E testing, etc. TestNG is in many ways similar to JUnit and NUnit. But in contrast to its competitors, its extensive features make it a lot more reliable framework. One of the major reasons for its popularity is its ability to structure tests and improve the scripts' readability and maintainability. Another reason can be the important characteristics like the convenience of using multiple annotations, reliance, and priority that make this framework popular among developers and testers for test design. You can refer to the TestNG tutorial to learn why you should choose the TestNG framework.

Chapters

  1. JUnit 5 vs. TestNG: Compare and explore the core differences between JUnit 5 and TestNG from the Selenium WebDriver viewpoint.
  2. Installing TestNG in Eclipse: Start installing the TestNG Plugin and learn how to set up TestNG in Eclipse to begin constructing a framework for your test project.
  3. Create TestNG Project in Eclipse: Get started with creating a TestNG project and write your first TestNG test script.
  4. Automation using TestNG: Dive into how to install TestNG in this Selenium TestNG tutorial, the fundamentals of developing an automation script for Selenium automation testing.
  5. Parallel Test Execution in TestNG: Here are some essential elements of parallel testing with TestNG in this Selenium TestNG tutorial.
  6. Creating TestNG XML File: Here is a step-by-step tutorial on creating a TestNG XML file to learn why and how it is created and discover how to run the TestNG XML file being executed in parallel.
  7. Automation with Selenium, Cucumber & TestNG: Explore for an in-depth tutorial on automation using Selenium, Cucumber, and TestNG, as TestNG offers simpler settings and more features.
  8. JUnit Selenium Tests using TestNG: Start running your regular and parallel tests by looking at how to run test cases in Selenium using JUnit and TestNG without having to rewrite the tests.
  9. Group Test Cases in TestNG: Along with the explanation and demonstration using relevant TestNG group examples, learn how to group test cases in TestNG.
  10. Prioritizing Tests in TestNG: Get started with how to prioritize test cases in TestNG for Selenium automation testing.
  11. Assertions in TestNG: Examine what TestNG assertions are, the various types of TestNG assertions, and situations that relate to Selenium automated testing.
  12. DataProviders in TestNG: Deep dive into learning more about TestNG's DataProvider and how to effectively use it in our test scripts for Selenium test automation.
