Developers’ Spring Boot tests may be passing, but can they really trust them? In this session, Philip Riecks reveals five critical testing mistakes that silently undermine a test suite's reliability and developers’ confidence in deployments.

He tackles the tough questions: Why do tests pass locally but fail in CI? When does `@MockBean` become the enemy? How can 100% coverage still miss critical bugs? Attendees will see real examples of tests that look correct but hide serious flaws.

The session shows how to identify and fix dangerous patterns: transaction rollback confusion, context pollution between tests, incorrect `@WebMvcTest` usage, time-dependent test failures, and the over-mocking trap.

Each pitfall comes with practical solutions and alternative approaches. Through code examples and debugging sessions, attendees will gain the skills to write tests that actually catch bugs before production. Philip will help transform their testing approach from “hope it works” to “know it works.”

Perfect for developers who have been burned by production issues despite “comprehensive” test suites.
