PatrolTester class

PatrolTester wraps a WidgetTester. It provides support for Patrol custom finder, a.k.a $.

If you want to do something that WidgetTester supports, but PatrolTester does not, you can access the underlying WidgetTester via tester field of PatrolTester.

import 'package:patrol_plus/patrol.dart';

void main() {
  patrolWidgetTest('Counter increments smoke test', (patrolTester) async {
    await patrolTester.pumpWidgetAndSettle(const MyApp());
    await patrolTester(#startAppButton).tap();
  });
}

To make test code more concise, patrolTester variable is usually called $, like this:

import 'package:patrol_plus/patrol.dart';
void main() {
  patrolWidgetTest('Counter increments smoke test', ($) async {
    await $.pumpWidgetAndSettle(const MyApp());
    await $(#startAppButton).tap();
  });
}

You can call PatrolTester just like a normal method, because it is a callable class.
