This live, instructor-led training in Copenhagen is tailored for individuals keen on mastering Java specifically for test automation. As a concise and intensive programme, it features ample hands-on exercises designed to swiftly equip participants with the core programming skills essential for software automation testing. The curriculum prioritizes Java fundamentals that can be applied directly and immediately to real-world test automation scenarios.

Please note that this course does not provide an in-depth analysis of test automation frameworks like Selenium. It also skips the traditional "Hello World" introductory path, as the focus is strictly on automation rather than general application development. The primary goal is to enable participants to begin working with test automation efficiently. If you already possess strong Java knowledge and prefer to jump directly into Selenium testing, we recommend exploring: Introduction to Selenium (https:\/\/www.nobleprog.com\/introduction-selenium-training).
