False positive, java/unused-reference-type and JUnit 5 classes

[mikeb01]

JUnit Tests using JUnit 5 are reported as java/unused-reference-type. This is because the JUnit 5 convention is to use package scoped class and method names. This rule should be checking for methods with JUnit annotations (e.g. @Test, @BeforeEach, @ParameterizedTest). The current check only looks for subsclassing of TestCase, which hasn't been applicable since JUnit 4.

Example test code that would be reported as unused.

class MyTest
{
    @Test
    void test()
    {
       // some test code.
    }
}

Thanks for the report. That looks indeed like a false positive.

Hi there! Is there a workaround for this issue? Could be solved by adding the following check not dead.getAMethod() instanceof TestMethod and or not dead instanceof TestClass and?
