Lewis John McGibbney updated NUTCH-3145:
----------------------------------------
Description:
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.
