Making Your Testcontainers Experience Smoother
summary
Shows concrete Testcontainers for Java tactics: use the MySQL and Elasticsearch modules, enable TLS via the module CA helper, run migrations once then snapshot and restore instead of rerunning, mark containers static or start them globally once and in parallel, use ram-backed volumes, increase Maven Surefire/Failsafe forks, enable testcontainers.reuse for local caching, profile with Java Flight Recorder + junit-jfr; measured runtime drops from ~4 minutes to 1:17 to 30s to 21s and finally ~5s.
