Presentation: To Test or Not to Test: The Dilemma of Customized solutions for Third-Party Tools

When extending third-party platforms with custom code, teams often face a recurring question: where does the platform's responsibility end and our testing begin? This talk explores the challenges of deciding what—and how much—to test when building custom extensions on top of established tools. We’ll discuss how to distinguish between out-of-the-box functionality you can rely on versus custom logic that requires dedicated coverage, and how to identify the right point in the project to start testing. Using a real-world example from our Keycloak customization, we’ll walk through the testing approach we adopted, the trade-offs considered, and the lessons learned.
