<p> Testing GUIs is essential to making applications safer and more robust. Even the simplest GUI can enclose some complexity. Any complexity needs to be tested: code without tests is a potential source of bugs. A well-tested application has a greater chance of success. GUI development has been slow to include automated testing as a core practice, because writing tests for GUIs is hard. In this session, we'll explore several practices that can simplify testing of Swing and JavaFX GUIs. </p> <p> Topics that will be covered include: <ul> <li>What robust GUI tests means</li> <li>Creating testable GUIs</li> <li>Troubleshooting failing tests</li> <li>Finding and fixing threading issues</li> <li>Applying test-driven development (TDD) to GUIs</li> <li>Available open source tools for GUI testing</li> </ul> </p>
