title: AssertEquals fails, because of multilines
body: <p>I have generated two same Strings with StringBuilder</p>
  
  <pre><code>for(Integer value : ans.keySet())
   answer.append(String.format("%d=%d\n", value, ans.get(value)));
  </code></pre>
  
  <p>But when I write</p>
  
  <pre><code>assertEquals(answer, answer1);
  </code></pre>
  
  <p>Test is failed and there are no diffrences. I work in Windows.</p>
