summary
Using Java 21 and JUnit 5, the talk examines six common testing anti-patterns that give a false sense of safety—examples include Coverage-Driven Development that tests nothing meaningful, overuse of mocks, and Thread.sleep() hacks that make tests slow and flaky. For each anti-pattern the presenter shows short code examples and concrete fixes to make tests faster, more reliable, and truly trustworthy.
