title: Is code coverage for all existing test cases?
body: <p>I have a doubt regarding code coverage.</p>
  
  <p>Consider the below scenario,</p>
  
  <p>If I am having the method <strong>Sample()</strong> with some parameters and I wrote say example 10 test cases for that method. </p>
  
  <p>While running code coverage, if a part of a code (say for example an if condition) is still not covered.</p>
  
  <p>So if I am going to cover that if condition by writing new test case,</p>
  
  <ul>
  <li>I can able to cover that code by using valid parameters alone(Using any one of an already existing test case).</li>
  </ul>
  
  <p>And my doubt is,</p>
  
  <p>Is that single test case is sufficient for that uncovered code? else I have to cover the code by repeating all the existing 10 test cases of that method?</p>
