How to run all (single and instrumental) tests with one click in Android Studio

Question

I am developing an Android application in Android Studio. I have unit tests and instrumental tests.

I want to run them all to see something is broken.

Now my workflow:

• go to project presentation
  • go to ${app}/src/androidTest/java/
  • right click this node and select Run 'All Tests'
  • select my device
  • run instrumental tests

then

• go to project presentation
  • go to ${app}/src/androidTest/java/${package}
  • right click this node and select Run 'Tests in ${package}'
  • run unit tests

What I'm really looking for is a big green button that launches all tests and reports OK / FAILED results for tests with both unit and tools. How can i do this?
