-------------------------------------------
Assignee: Lewis John McGibbney
> Upgrade to JUnit 6
> ------------------
>
> Key: NUTCH-3145
> URL: https://issues.apache.org/jira/browse/NUTCH-3145
> Project: Nutch
> Issue Type: Improvement
> Components: test
> Reporter: Lewis John McGibbney
> Assignee: Lewis John McGibbney
> Priority: Minor
> Fix For: 1.22
>
>
> JUnit 6 was released on September 30, 2025 (with the latest patch 6.0.2 on
> January 6, 2026). It builds directly on JUnit 5's Jupiter model, so core
> annotations, extensions, and test-writing philosophy remain largely
> unchanged. The transition should be MUCH smoother than from JUnit 4 to 5
> (NUTCH-2887).
>
> |Aspect|JUnit 5|JUnit 6|
> |--------|---------|---------|
> |*Latest Stable Version*|5.14.x series|6.0.2 (released January 6, 2026)|
> |*Minimum Java Version*|Java 8|Java 17|
> |*Minimum Kotlin Version*|Lower versions supported|Kotlin 2.2+|
> |*Versioning Scheme*|Platform had separate versioning (e.g., 1.x); Jupiter
> and Vintage shared 5.x|Unified single version across Platform, Jupiter, and
> Vintage (e.g., all 6.0.2)|
> |*Vintage Engine (JUnit 3/4 support)*|Fully supported|Deprecated (with
> INFO-level warnings during discovery); intended only for temporary migration|
> |*Removed Modules*|Included junit-platform-runner and junit-platform-jfr|Both
> modules removed|
> |*CSV Parsing (@CsvSource, @CsvFileSource)*|Used univocity-parsers|Migrated
> to FastCSV (faster, better error handling, RFC-compliant; minor behavior
> differences for malformed input)|
> |*Kotlin Support*|Limited coroutine integration|Native support for suspend
> modifier on test and lifecycle methods|
> |*Nullability Annotations*|No built-in support|Integrates JSpecify
> (@Nullable, @NonNull) for improved static analysis|
> |*Other Notable Changes*| - |Deterministic (but non-obvious) ordering of
> @Nested classes<br>Cancellation/fail-fast support improvements<br>Removal of
> many deprecated APIs<br>Built-in enhancements for performance and modern JDK
> compatibility|
> |*Migration Effort*| - |Generally low for pure Jupiter tests; main impacts
> are Java version upgrade and Vintage deprecation. See official migration
> guide:
> [https://github.com/junit-team/junit-framework/wiki/Upgrading-to-JUnit-6.0]|
> JUnit 6 is an evolutionary update focused on modernization, cleanup, and
> dropping legacy support. Most existing Jupiter tests run unchanged.
