title: Code coverage percentage in unit testing
body: <p>I have a class, having 3 methods(in python) .</p>
  
  <pre><code>class MyClass:
      def A(self):
            .......
      def B(self):
           ........
      def C(self):
           ........
  </code></pre>
  
  <p>I have written unit test case for only one method A. This unit test covers each line of the method A. That is we don't have any if...else or any branching constructs. </p>
  
  <p>What would  be the code coverage percentage? </p>
  
  <p>Again if I write another unit test case for 2nd method of the class covering all lines.  What would be the code coverage percentage now? </p>
