JUnit 5 ParameterizedTest results not properly flagged for complex arguments

[JGitHub01]

When parameters for a ParameterizedTest is provided by MethodSource that return stream of Arguments of non primitive type e.g. double[], the test results are not flagged with a green check for success test. Instead, it shows a grey circle without a dropdown that show test result for each test case.

Example Code:

public class ExampleTest {
  @ParameterizedTest
  @MethodSource("parameters")
  void shouldDoParameterizedTest(double[] s) {
    assertNotNull(s[0]);
    assertNotNull(s[1]);
  }

  static Stream<Arguments> parameters() {
    return Stream.of(Arguments.of(new double[] {
        0.01d, 0.05d
    }), Arguments.of(new double[] {
        0.02d, 0.04d
    }));
  }
}

Looks like passing array such as double[] is what cause the issue. If I pass List<Double> as the argument, the issue goes away.

Thank s for reporting the issue. Looks like it's due to the different parameter type name returned from the item searcher and runner.

The searcher uses double[] while the runner is referencing the method using the binary name of the parameter type: [D, this mismatch causes the error.

Any contribution is welcome about this issue.

I think this may be related to #1617
