title: Sonar: Add some tests to this class
body: <p>I have an util class where I create Fake date for my unit test, I put it in test part of my Object:</p>
  <pre><code>public class FakeDataToTest {
    //.. fake objects
  }
  </code></pre>
  <p>But Sonar give a Blocker, because this class doesn't contain unit test, in another word not have a method annotated <code>@Test</code>, the message of sonar is:</p>
  <pre><code>Add some tests to this class.
  </code></pre>
