ozzie.flutter

Ozzie is your testing friend. Ozzie will take an screenshot during integration tests whenever you need.

How it works

Add ozzie to your pubspec.yaml as a dev_dependency:

dev_dependencies:
    ozzie: <latest_version_here>

In your Flutter integration tests, create an instance of Ozzie, pass the FlutterDriver, give it a groupName and ask it to takeScreenshot. That simple! And whenever you have finished with tests, you can create an HTML report by asking Ozzie to generateHtmlReport.

Here's an example:

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

void main() {
  FlutterDriver driver;
  Ozzie ozzie;

  setUpAll(() async {
    driver = await FlutterDriver.connect();
    ozzie = Ozzie.initWith(driver, groupName: 'counter');
  });

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

  test('initial counter is 0', () async {
    await ozzie.takeScreenshot('initial_counter_is_0');
  });

  test('initial counter is 0', () async {
    driver.tap(find.byType('FloatingActionButton'));
    await ozzie.takeScreenshot('counter_is_1');
  });
}

After this, a report will be generated inside your project as ozzie/index.html:
