They will be guided on handling various web elements, managing browser sessions, and implementing waits for dynamic content. This foundational knowledge is essential for any automation tester working in a Java environment.
2) TestNG
TestNG is a testing framework inspired by JUnit but designed to be more powerful and flexible. It allows testers to organize test cases in a clear and logical manner, providing features such as annotations, groups, and parameterization. In the training program, students will discover how to set up TestNG with their Selenium scripts and run tests in parallel. Additional topics include generating test reports and managing dependencies between tests, which are critical for effective test execution and collaboration in team environments.
3) Maven
Maven is a build automation tool mainly used for Java projects. It simplifies project management by providing a standard way to manage project dependencies, build lifecycle, and documentation. In the course, students will learn how to configure Maven in their Selenium projects, including managing libraries and handling project dependencies efficiently. This knowledge ensures that students can maintain and scale their automation projects effectively as they grow, making it a vital skill for any automation tester.
4) Apache POI
Apache POI is a powerful library for reading and writing Microsoft Office files, particularly Excel spreadsheets, in Java. Since test data often resides in Excel files, students will learn how to utilize POI to read test data for their Selenium scripts effectively. The training will cover various functionalities, including creating Excel reports of test results, thus enabling testers to validate output and share findings efficiently. Mastery of Apache POI enhances the capabilities of automation tests by allowing dynamic data driven testing.
5) Jenkins
Jenkins is an open source automation server that supports building, deploying, and automating software projects. It plays a crucial role in continuous integration and continuous delivery (CI/CD) pipelines. During the course, students will learn how to integrate Selenium scripts with Jenkins, allowing for automated test execution as part of the build process. They will explore the configuration of Jenkins jobs, scheduling, and monitoring test results. Understanding Jenkins equips students with the necessary skills to implement automation in real world projects effectively.
6) Git
Git is a version control system that helps track changes in code repositories. It is essential for collaborating on software development projects, enabling multiple testers to work simultaneously without conflict. In the training program, students will learn Git basics, including how to clone repositories, make commits, and manage branches effectively. By incorporating Git into their workflow, students will learn valuable skills for maintaining version control over their automation test scripts, making collaboration and project management much more efficient.
