bdd_framework_patrol 1.0.0

Patrol integration for bdd_framework. Lets you write BDD scenarios that run as Patrol integration tests, with access to the PatrolIntegrationTester in every step.

bdd_framework_patrol

Patrol integration for bdd_framework.

The code in this package was contributed by Kahoulam.

Write BDD scenarios with bdd_framework and run them as Patrol integration tests. Every .code() step and the final .run() callback receive the PatrolIntegrationTester (usually named $).

This runner is a separate package so that bdd_framework itself doesn't depend on Patrol. Add it only to projects that use Patrol.

Install

dev_dependencies:
  bdd_framework_patrol: ^1.0.0
  patrol: ^4.5.0

Then set up Patrol itself (native configuration, the patrol: section in your app's pubspec.yaml, and the patrol_cli) as described in the Patrol documentation.

Usage

Import bdd_framework_patrol.dart instead of the other bdd_framework runners (dart_test.dart, flutter_test.dart, flutter_widget_test.dart). It re-exports the whole BDD API.

import 'package:bdd_framework_patrol/bdd_framework_patrol.dart';
import 'package:flutter/material.dart';
import 'package:flutter_test/flutter_test.dart';

void main() {
  var feature = BddFeature('Greeting');

  Bdd(feature)
      .scenario('Shows a greeting.')
      .given('The app is started.')
      .code((ctx, $) async {
    await $.tester.pumpWidget(const MaterialApp(
      home: Scaffold(body: Text('Hello')),
    ));
  })
      .when('The user looks at the screen.')
      .then('The greeting is visible.')
      .run((ctx, $) async {
    expect($('Hello'), findsOneWidget);
  });
}

Example and table values work as usual, through ctx.example and ctx.table().

Run the tests with patrol test. The unit tests in test/ run with flutter test.

By default, RenderFlex overflow errors are printed but don't fail the test. Set BddPatrol.ignoreOverflow = false to make them fail it.

Security note

Patrol is a device-automation tool. While a Patrol test runs, it starts local test-control services: a Dart test service (default port 8082) and a native automation service (default port 8081). They have no authentication. Depending on the device and network setup, other machines may be able to reach them. Run Patrol tests on test devices and networks you trust, with non-sensitive data. The Patrol CLI also collects analytics by default. Set PATROL_ANALYTICS_ENABLED=false to turn it off.

None of this happens when you only import package bdd_framework.
