Autopilot #

A test driver for Flutter to do QA testing without sharing app source code. It exposes a JSON API using an HTTP server running inside the app. Using these APIs you can write tests in any language for your Flutter app.

Getting started #

Add autopilot to pubspec:


Create main_test.dart along side of your main.dart file like this:

import 'main.dart' as app;
import 'package:autopilot/autopilot.dart';

final autopilot = Autopilot();

void main() {

Run your app on device/emulator:

flutter run --release --target lib/main_test.dart

On Android forward port 8080 so that you can access it via localhost:

adb forward tcp:8080 tcp:8080

Consider following example:

  "Hello World!",
  key: Key("txtGreet"),

Example of a test in python using pytest:

import requests

root = "http://localhost:8080"

def get(path):
    return requests.get(root + path).json()

def test_greet():
    greet = get("/texts?key=txtGreet")[0]
    assert greet["text"] == "Hello World!"

Run it:

python -m pytest

Inspiration #

Flutter has a really amazing testing suite for Unit, UI and Integration testing. But one problem is that you need to know/learn Dart and you have to share the source code of the app to the person who writes tests. This is doesn't work in every work environments.

But Flutter framework is so transparent I was able to tap into its internals and build a JSON API which can provide pretty much everything you need to write UI automation tests.
