             Summary: Inconsistent console reporter output on failures for parameterized tests, with/without rerunFailingTestsCount
                 Key: SUREFIRE-2151
                 URL: https://issues.apache.org/jira/browse/SUREFIRE-2151
             Project: Maven Surefire
          Issue Type: Bug
          Components: Maven Surefire Plugin
    Affects Versions: 3.0.0-M9
            Reporter: Ralph Weires


The way in which test-failures are being displayed with the console-reporter is not ideal and partly inconsistent, in particular for (e.g. JUnit5) parameterized tests.

Taking a small (JUnit5) snippet of a dummy-test as example:
{code:java}
public class DummyTest {
  @ParameterizedTest
  @CsvSource({"yes", "no", "yes", "yes", "no"})
  public void dummyTest(String param) {
    testInternal(param);
  }

  private void testInternal(String arg) {
    if (arg.equals("no")) {
      Assertions.fail("If you say 'no', it's a no");
    }
  }
}{code}
Running this with surefire will display an error like this (the summary in the end):
{code:java}
[...]

[INFO] Results:
[INFO]
[ERROR] Failures:
[ERROR]   DummyTest.dummyTest:16->testInternal:21 If you say 'no', it's a no
[ERROR]   DummyTest.dummyTest:16->testInternal:21 If you say 'no', it's a no

[...]{code}
The failures do show parts of the problematic code-path, but don't have any information about the actual invocations of the parameterized tests that failed (in the example, invocations 2+5 of the 5). And while it is possible to see more details in the stack traces (i.e. scrolling up in the output), it would be quite nice see more details right away.

If the _rerunFailingTestsCount_ is used (here with value 2), the output does show more details right away - namely the actual problematic invocations:
{code:java}

[...] {code}
In fact, this is currently the main reason for us to even use the _rerunFailingTestsCount_ flag - regardless of what that flag is actually meant for - which feels rather weird.

 

Would it make sense to align this somehow?
