Permissions are always granted in UI tests-CodePudding

I'm trying to test the permission request flow - if the proper screens and request dialogs are shown when user invokes some action requiring ungranted permission, but I can't make the request permission dialog appear in my tests, as inside the tests permissions are always granted, so this returns a permissionStatus == GRANTED and I need them to be denied.

val context: Context = InstrumentationRegistry.getInstrumentation().context
val permissionStatus = ContextCompat.checkSelfPermission(context, permissionNeeded)

Have anybody stumbled into this issue, or found another way of testing permission flows?

I've tried this also with espresso activityRule, without resetting to homepage etc, but no luck, so... full - minimal - code example is below:

@SdkSuppress(minSdkVersion = 23)
@RunWith(AndroidJUnit4::class)
class MainActivityTest {

    private lateinit var device: UiDevice

    @After
    fun tearDown() {
        InstrumentationRegistry.getInstrumentation().uiAutomation
            .executeShellCommand("pm grant com.example.odometer android.permission.ACCESS_COARSE_LOCATION")
    }

    @Before
    fun startMainActivityFromHomeScreen() {
        device = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation())
        device.pressHome()

        val launcherPackage: String = device.launcherPackageName
        require(launcherPackage.isNotBlank())
        device.wait(
            Until.hasObject(By.pkg(launcherPackage).depth(0)),
            LAUNCH_TIMEOUT
        )

        val context = ApplicationProvider.getApplicationContext<Context>()
        val intent = context.packageManager.getLaunchIntentForPackage(
            BASIC_SAMPLE_PACKAGE
        )?.apply {
            // Clear out any previous instances
            addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK)
        }
        context.startActivity(intent)

        // Wait for the app to appear
        device.wait(
            Until.hasObject(By.pkg(BASIC_SAMPLE_PACKAGE).depth(0)),
            LAUNCH_TIMEOUT
        )
    }

    @Test
    fun testPermissionDialog() {
        val context: Context = InstrumentationRegistry.getInstrumentation().context
        val permissionStatus =
            ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION)
        assertNotEquals(PackageManager.PERMISSION_GRANTED, permissionStatus)
    }
}

Edit: It happens also if the app is uninstalled before test.

Tested on emulator with API: 29 and 31_arm64
