Android Marshmallow: Test permissions with Espresso?

Question

The new permissions scheme introduced by Android Marshmallow requires checking for specific permissions at runtime, which implies the need to provide different flows dependi

Answer 1

If you need to set a permission for a single test or during runtime rather than a rule you can use this:

PermissionRequester().apply {
    addPermissions(android.Manifest.permission.RECORD_AUDIO)
    requestPermissions()
}

e.g.

@Test
fun openWithGrantedPermission_NavigatesHome() {
    launchFragmentInContainer().onFragment {
        setViewNavController(it.requireView(), mockNavController)
        PermissionRequester().apply {
            addPermissions(android.Manifest.permission.RECORD_AUDIO)
            requestPermissions()
        }
    }

    verify {
        mockNavController.navigate(R.id.action_permissionsFragment_to_homeFragment)
    }
}
