title: "Path bounds exceeded" while doing a Pex unit test
body: <p>I am trying to generate a Pex unit test on an example program. I created a webpage with <code>Default.aspx</code>. Now I opened the <code>default.aspx.cs</code> file and added the below given code to the code behind:</p>
  
  <pre><code>public int Add(int n1,int n2)
  {
  return n1+n2;
  }
  public int Subtract(int n1,int n2)
  {
  return n1-n2;
  }    
  </code></pre>
  
  <p>Now I right clicked inside the <code>default.aspx.cs</code> file, clicked "Run Pex". In the Pex exploration results I am getting a message "Path bounds exceeded".</p>
  
  <p>I don't understand &ndash; what does this mean and what should I do to get my unit test to pass?</p>
