Learning Selenium: Structure, Scale, Run, and Optimize Automated Tests

Course details

In this course, Playwright test automation specialist Qambar Raza guides you through the essentials of Selenium, a cornerstone of browser test automation, including how to write and run tests on both local machines and cloud-based platforms like GitHub Actions. Learn how to set up Selenium, grasp the intricacies of debugging, and capture evidence of test failures using screenshots. Gain proficiency in structuring tests with page object models and optimizing test execution through parallelization and Selenium Grid. Explore the techniques for leveraging Selenium Manager and integrating wire mock for efficient testing workflows. With each lesson building on the previous, this course actively engages you in fixing, coding, and running tests as a real-world test automation engineer.

Learning objectives
Build a maintainable Selenium test framework using Java and JUnit.
Configure and run Selenium Grid using Docker to scale UI test execution.
Improve test speed and reliability using smart waits and parallel execution.
Integrate accessibility checks with axe-core and mock APIs using WireMock.
Run tests in GitHub Actions CI and debug flaky remote tests.
