summary

Examples include ArchUnit enforcing package and naming rules, Awaitility reducing async test waits (roughly awaitility halves wait versus thread sleep), JaCoCo attached to a JVM with the caveat JaCoCo writes report on JVM stop, PIT mutation testing exposing weak unit tests, Testcontainers launching a MySQL container for tests, Gatling plus JDK Mission Control for profiling, and Apache Spark processing a 29 GB Amazon dataset (about 29 GB, 41 million records and 28 matches for "Java programming language"). OpenRewrite auto-upgrades JUnit4 to JUnit5 and rewrites code, OptaPlanner schedules slots but fails when rules are mis-specified.
