[java] TestClassWithoutTestCases - false-positive for test classes extending a class with tests (in nested classes)

[Wolf2323]

Affects PMD Version: 7.1.0

Rule: TestClassWithoutTestCases

Description:
In PMD 6 this was no issue, now in PMD 7 a nested test class is now detected as TestClassWithoutTestCases. I guess previously the class was not detected as test class at all. Now it is detected, and yes it actually has no tests, but they are on the super class.

Code Sample demonstrating the issue:

public class SpeedProfilerTests extends TimeProfilerTests {
	@Nested
	class operations extends TimeProfilerTests.operations {
		@Override
		protected TimeProfiler makeProfiler() {
			return new SpeedProfiler("foo");
		}
	}

Expected outcome:
No violations, as the super class actually has test cases

[INFO] PMD Failure: works.reload.recore.util.operations:22 Rule:TestClassWithoutTestCases Priority:3 The class 'operations' might be a test class, but it contains no test cases..
