Granting Permissions

• JUnit5 apparently does not support @Rule: http://www.douevencode.com/articles/2018-06/grant-permission-no-rule/ “JUnit5, which is ultimately the future discourages to use @Rules"

• With the above said, we can hack in a workaround to be able to grant permissions:

  • import androidx.test.runner.permission.PermissionRequester;
    
    public class SomeClass
    {
        // Hacky workaround for JUnit5 not supporting @Rule
        private void GrantPermissions(String ... permissions)
        {
            PermissionRequester pr = new PermissionRequester();
            pr.addPermissions(permissions);
            pr.requestPermissions();
        }
    }

  • Usage:

    public class SomeClass
    {
        //...
        
        @Test
        public void SomeExampleTest()
        {
            GrantPermissions(android.Manifest.permission.BLUETOOTH_SCAN);
        
            VictorBleDeviceManager dm = new VictorBleDeviceManager(ApplicationProvider.getApplicationContext());
            List<VictorDeviceInfo> scannedDevices = dm.ScanForDevices().get();
            assertTrue(scannedDevices.isEmpty());
        }
    }
