title: I want to run unit test and espresso test cases a specific build type
body: <p>I have a multiple falvoured and multiple build type project..having some espresso and unit test cases which are running successfully but to run them successfully i have mocked my api responses currently i change my build type manually in android studio to stagging and then run those tests. Now i am integrating my project with jenkins and in jenkins my tests failed becuase jenkins is running test cases on all build types.. So long story Short I want  my test cases to run only using staging build type.. </p>
