If you are using the latest 'com.android.support.test.espresso:espresso-core:3.0.1' library for espresso this can be done in a single line of code. All you need to do is just add a rule in in Test class and keep adding the permissions you need as function parameters to grant function. See below:

@Rule
public GrantPermissionRule mRuntimePermissionRule = GrantPermissionRule .grant(Manifest.permission.READ_PHONE_STATE, Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.BLUETOOTH,Manifest.permission.RECORD_AUDIO);
