How start identical jobs with different parameters in parallel execution?

I have a build job and a test job parameters.

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.

                build job  
                   |  
                  / \  
         test job    test job
   with one params    with other params
            |             |

How to accomplish this and whether it is possible to perform without having to write your own plugin?

Thanks!
