Developed an end-to-end UI automation test for the DemoQA Book Store application in the RedRoverSchool/JenkinsQA_Java_2025_fall repository, establishing the initial foundation for automated regression checks. The work focused on automating navigation, book search, and detail verification using Java, Selenium, and TestNG, with WebDriver configured for headless execution to support stable continuous integration. To further enhance reliability, the test suite included logic for ad banner removal, minimizing UI disruptions during automated runs. This contribution introduced the first DemoQA test to the codebase, enabling ongoing expansion of test coverage and supporting maintainable, repeatable quality assurance for Book Store workflows.
