The release includes ten extensions: system property and environment variable management (@ClearSystemProperty, @SetSystemProperty, @ClearEnvironmentVariable, @SetEnvironmentVariable), default locale and time zone control (@DefaultLocale, @DefaultTimeZone), Cartesian product tests (@CartesianProductTest), disabling tests by display name (@DisableIfDisplayName), numeric range sources for parameterized tests, declarative report entries (@ReportEntry), retrying flaky tests (@RetryingTest), and standard I/O mocking (@StdIo). All extensions are thread-safe and include annotations to coordinate parallel test execution when global state is involved. Available via Maven and Gradle. ## Full article daily.dev links to this article rather than hosting it.
