BazelJUnitOutputListener Logs Empty TestSuite on Test Suite Level Failure

[amishra-u]

Issue

When a test suite fails at the suite level, such as when a @BeforeClass method fails in a test class, BazelJUnitOutputListener logs an empty instead of properly capturing the failure. While Bazel logs the output for each test in the test class with the test result reflecting the test suite failure.

Steps to Reproduce:

• Create a JUnit test class with a @BeforeClass method that fails (e.g., throws an exception).

  public static class TestSuiteError {
    @BeforeClass
    public static void setup() {
        throw new RuntimeException("test suite error");
    }

    @Test
    public void test1() {
      System.out.println("test1");
    }

    @Test
    public void test2() {
      System.out.println("test2");
    }
  }

• Check the XML output generated by BazelJUnitOutputListener. The corresponding to this class will be empty.

Expected Behavior:

• Each test in the test suite should be logged with same error log as parent test suite. Idenitical to Bazel XmlWriter.

Actual Behavior:

• BazelJUnitOutputListener logs an empty .
