Are Your Test Slowing You Down?
summary
Diagnoses three concrete slowdowns: writing tests (IDE templates, IntelliJ live templates and JetBrains AI assistant generating flaky or inconsistent unit tests), troubleshooting flaky tests (use retries to detect flakiness, failure clustering via Develocity ML, quarantine and fix or delete), and running tests (Gradle remote build cache cuts a Spring Boot build 20m → 3m, test distribution and parallel agents, Netflix cuts a 1h cycle to 5m with massive parallelism). Practical patterns: red green refactor, given when then.
