JUnit 3 test can be JUnit 4

Reports JUnit 3 test classes that can be converted to JUnit 4 test classes.

Example:

  public class MainTestCase extends junit.framework.TestCase {
    public void test() {
      Assert.assertTrue(true);
    }
  }

After the quick-fix is applied:

  public class MainTestCase {
    @org.junit.Test
    public void test() {
      Assert.assertTrue(true);
    }
  }
