5.2.0-M1

Date of Release: April 15, 2018

Scope: JUnit BOM, support for Maven Surefire 2.21.0 allowing builds with Java 9 and Java 10, argument aggregation and widening primitive conversion for arguments in parameterized tests, external factory methods for @MethodSource, as well as various minor improvements and bug fixes.

For a complete list of all closed issues and pull requests for this release, consult the 5.2 M1 milestone page in the JUnit repository on GitHub.

Overall Improvements

  • JUnit BOM: To ease dependency management using Maven or Gradle, a Bill of Materials POM is now provided under the org.junit:junit-bom:5.2.0-M1 Maven coordinates.

JUnit Platform

Bug Fixes

  • Tag expressions containing spaces are now supported in the JUnit Platform Maven Surefire provider.

  • Duplicate --config keys supplied to the ConsoleLauncher are now reported properly.

  • Exceptions thrown in Node.after() (in the HierarchicalTestEngine infrastructure) no longer mask earlier exceptions.

New Features and Improvements

  • The JUnit Platform Surefire Provider (junit-platform-surefire-provider) now works with and requires Surefire 2.21.0 which allows it to be used with Java 9 and Java 10.

  • The default include pattern for filtering class names now matches test classes whose names either start with Test or end with Test or Tests.

    • This pattern is used by the ConsoleLauncher, the JUnit Platform Gradle Plugin, and the JUnitPlatform runner.

JUnit Jupiter

Bug Fixes

  • Exceptions thrown by an AfterAllCallback no longer mask exceptions thrown at the class level when using the @TestInstance(PER_CLASS) lifecycle mode.

New Features and Improvements

  • New assertDoesNotThrow() methods in Assertions which assert that the execution of a given code block does not throw any kind of exception.

  • New fail() method in Assertions makes it possible to fail a test without an explicit failure message.

  • Implicit support for widening primitive conversion for an argument supplied to a @ParameterizedTest.

    • For example, a parameterized test annotated with @ValueSource(ints = { 1, 2, 3 }) can be declared to accept an argument of type int, long, float, or double.

  • @MethodSource now supports static factory methods declared in external classes referenced by fully qualified method name.

  • Support for aggregation of multiple @ParameterizedTest arguments into a single object.

5.1.1

Date of Release: April 8, 2018

Scope: Bug fixes and minor improvements since the 5.1.0 release

For a complete list of all closed issues and pull requests for this release, consult the 5.1.1 milestone page in the JUnit repository on GitHub.

JUnit Platform

New Features and Improvements

  • New findAllClassesInModule() method in ReflectionSupport which enables third-party TestEngine implementations to scan for classes in modules — for example, when processing a ModuleSelector during the discovery phase.

JUnit Jupiter

New Features and Improvements

  • The ParameterContext API used in ParameterResolver implementations now includes the following convenience methods for looking up annotations on parameters. Extension authors are strongly encouraged to use these methods instead of those provided in the core java.lang.reflect.Parameter API due to a bug in javac on JDK versions prior to JDK 9 which causes lookups for annotations on parameters in inner class constructors to fail consistently — for example, when resolving a parameter for a @Nested test class constructor.

    • boolean isAnnotated(Class<? extends Annotation> annotationType)

    • Optional<A> findAnnotation(Class<A> annotationType)

    • List<A> findRepeatableAnnotations(Class<A> annotationType)

JUnit Vintage

No changes.
