title: Simultaneously running 2 or more boost testcases belonging to different test suites via cmd
body: <p>Consider the following scenario:</p>
  
  <pre><code>BOOST_AUTO_TEST_SUITE(suite1)
  {
      BOOST_AUTO_TEST_CASE(case1)
      {
          //my test code here
      }
  }
  
  BOOST_AUTO_TEST_SUITE(suite2)
  {
      BOOST_AUTO_TEST_CASE(case1)
      {
          //my test code here
      }
  
      BOOST_AUTO_TEST_CASE(case2)
      {
          //my test code here
      }
  }
  </code></pre>
  
  <p>Now, if I want to run suite1/case1 and suite2/case2 at once, I try the following command line argument:</p>
  
  <pre><code>MyProject.exe --run_test="suite1/case1, suite2/case2"
  </code></pre>
  
  <p>But this doesn't seem to run.</p>
  
  <p>I know that I can separately run these test cases, as:</p>
  
  <pre><code>MyProject.exe --run_test="suite1/case1"
  </code></pre>
  
  <p>and</p>
  
  <pre><code>MyProject.exe --run_test="suite2/case2"
  </code></pre>
  
  <p>But I want to run them together at one go. What should I do?
  Thanks in advance :)</p>
