For Testing

import 'package:flutter_driver/flutter_driver.dart'; import 'package:test/test.dart';

void main() {

group('URL Opening Tests', () { FlutterDriver? driver;

setUpAll(() async { driver = await FlutterDriver.connect(); });

tearDownAll(() async { if (driver != null) { driver?.close(); } });

test('Open URL Using url_launcher', () async { await driver?.tap(find.byType('ElevatedButton'));

});

}); }

At last I have successfully achieved it by using chrome for Testing Browser and same version chrome webdriver but it has limitations like we cannot launch the application on local host directly but after running the application or compiling the application it will be hosted on a local host port and then we have to run that port on chrome for Testing Browser.
