title: Fixing Branch Coverage Sonar issue
body: <p>I am trying to run sonar and i take a sample of my code a  sampleClass to fix the branch coverage issue:</p>
  
  <p>The issue was
  <strong>117 more branches need to be covered by unit tests to reach the minimum threshold of 65.0% branch coverage.</strong></p>
  
  <p>I was trying to let my test cases cover many branches in the sample class.</p>
  
  <p>but the number 117 cannot be changed after many trials.
  What i have to do to fix this issue? </p>
