But to answer your question... 5.0 M6... which _just_ got released: https://github.com/junit-team/junit5/releases/tag/r5.0.0-M6 馃槈

maven-surefire-plugin:2.20 produces the OOM. See for https://github.com/junit-team/junit5/issues/855 details.

The underlying error is: org.junit.platform.commons.util.PreconditionViolationException: Cannot convert instance of [I into a Stream: [I@38c6f217

If you change the return type to IntStream, it works:

  public static IntStream intdata() {
    return IntStream.of(3, 24, 12);
  }
sormuras picture sormuras on 17 Jul 2017

About to enhance the CollectionUtils.toStream with:

    if (object instanceof double[]) {
          return DoubleStream.of((double[]) object).boxed();
    }
    if (object instanceof int[]) {
          return IntStream.of((int[]) object).boxed();
    }
    if (object instanceof long[]) {
          return LongStream.of((long[]) object).boxed();
    }

How about other primitive array types?

marcphilipp picture marcphilipp on 17 Jul 2017

Will also add support for:

  • boolean[]
  • byte[]
  • char[]
  • float[]
  • short[]
