Testing is the backbone of any robust Spring Boot application. Yet, many developers make avoidable mistakes that lead to flaky, slow, or unreliable tests. If you’ve ever faced issues like tests randomly failing, slow build times, or struggling with mocks, this post is for you! Let’s dive into the best practices that will ensure your Spring Boot tests are fast, reliable, and maintainable. 1. Use the Right Testing Strategy Spring Boot offers different testing approaches, and using the wrong one can make your tests unnecessarily slow or unreliable. Unit Tests: Focus on testing individual components (e.g., services, repositories) without Spring Context. Integration Tests: Test how different components interact using an embedded database or mock dependencies. End-to-End (E2E) Tests: Validate the entire application behavior, including database and external services.
