title: How to compare two Set collections in Java for unit tests?
body: <p>Is <code>assertTrue(SetUtils.equals(test1, test2), is(false));</code> (solution referred from <a href="https://www.mkyong.com/java/java-how-to-compare-two-sets/" rel="nofollow noreferrer">https://www.mkyong.com/java/java-how-to-compare-two-sets/</a> where a SetUtils class is defined) 
  the only correct approach for testing if two sets contains the same values or currently directly using <code>assertEquals(test1,test2);</code> is supported?</p>
