Flutter integration tests won't run - flutter

Question

I am trying to write some integration tests using the flutter driver based off of the example here: https://flutter.io/testing/. I am able to get the app to deploy, but all I get back is awaiting for app response.
I'm really not sure what else to do as it just sits and waits.
Here's what I see in the terminal.
flutter drive --target=test_driver/home_category_list_scroll.dart

Here's are the first few lines of the test.
void main() {
group('scrolling performance test', () {
FlutterDriver driver;
setUpAll(() async {
// Connects to the app
driver = await FlutterDriver.connect(dartVmServiceUrl: 'http://127.0.0.1:54270');
});
tearDownAll(() async {
if (driver != null) {
// Closes the connection
driver.close();
}
});
test('measure', () async {

Thank you for any ideas you can give me.

Answer 1

Could you check if an Xcode build config is set that may be overriding the target file flutter drive was running? I found a similar issue and setting flavors worked on the integration test for them.

Answer 2

use flutter run and look at the url that returns in the console where the app is running, that is the one you should use in your dartVmServiceUrl parameter
