During October 2025, Filip Dniko developed an end-to-end UI automation test for the DemoQA Book Store within the RedRoverSchool/JenkinsQA_Java_2025_fall repository. Using Java, Selenium, TestNG, and WebDriver, he automated navigation, book search, and detail verification flows, establishing the first automated test for this application in the codebase. His approach included configuring headless browser execution and removing ad banners to improve continuous integration stability. While the work focused on a single feature and did not address bug fixes, it laid a technical foundation for future regression testing and broader coverage of Book Store workflows in the project.
