Trying to Run the Gatling Test in Play project but no Tests were executed!

Hey Guys,
I am pretty new to the Gatling and I am trying to add test in the play Project, when I put the same code in the normal sbt project it works but as soon as I put the code in the play project it says no test to execute, maybe I am doing some thing wrong. Please help me out here.

Link to my build.sbt :

I have checked it by placing my test inside the test folder and as a separate folder.
