title: How start identical jobs with different parameters in parallel execution?
body: <p>I have a build job and a test job parameters.</p>
  
  <p>I want to be after the build job, simultaneously run test job with one parameter and the same test job with different parameters in parallel execution.</p>
  
  <pre><code>                build job  
                     |  
                    / \  
           test job    test job
     with one params    with other params
              |             |
  </code></pre>
  
  <p>How to accomplish this and whether it is possible to perform without having to write your own plugin?</p>
  
  <p>Thanks!</p>
