Testing Flutter Apps With Appium

Google's Flutter is an open-source tool for developing native mobile apps. It enables developers to create cross-platform apps for both Android and iOS using a single codebase and programming language.

You can now test Flutter apps on the LambdaTest Appium testing platform across 3000+ real Android and iOS devices. LambdaTest supports Appium’s Flutter driver that lets you test Flutter apps using the Appium framework. To test Flutter apps, you will need to upload apps on LambdaTest cloud servers and then run your automated tests.

Prerequisites​

Before automating Flutter apps using Appium, make sure you have the following things configured.

  1. Your Flutter App must be compiled in debug or profile mode, as Appium Flutter Driver does not support Flutter App running in release mode.

  2. Add the below dependencies in Flutter app's pubspec.yaml

 dev_dependencies:
   test: Demo
   flutter_test:
     sdk: flutter
   flutter_driver:
     sdk: flutter
  1. In main.dart file, ensure the app has enableFlutterDriverExtension() enabled before runApp.
void main() {
    enableFlutterDriverExtension();
    init();
    runApp(MyApp());
 }
  1. Set the automationName capability to flutter in Appium desired capabilities.
 desiredCapabilities.setCapability("automationName", "flutter");

Shown below is the test script for automating Flutter apps on LambdaTest platform.

import os

from appium.webdriver import Remote
from appium_flutter_finder.flutter_finder import FlutterElement, FlutterFinder

# Example

driver = Remote('http://<LT username>:<LT accesskey>@mobile-hub.lambdatest.com/wd/hub/', dict(
    platformName='Android',
    automationName='flutter',
    platformVersion='11',
    deviceName='Google Pixel 4',
    app='<App URL>',
    isRealMobile=True
))

finder = FlutterFinder()

text_finder = finder.by_text('You have pushed the button this many times:')
text_element = FlutterElement(driver, text_finder)
print(text_element.text)

key_finder = finder.by_value_key("next_route_key")
goto_next_route_element = FlutterElement(driver, key_finder)
print(goto_next_route_element.text)
goto_next_route_element.click()

back_finder = finder.page_back()
back_element = FlutterElement(driver, back_finder)
back_element.click()

tooltip_finder = finder.by_tooltip("Increment")
driver.execute_script('flutter:waitFor', tooltip_finder, 100)

floating_button_element = FlutterElement(driver, tooltip_finder)
floating_button_element.click()

counter_finder = finder.by_value_key("counter")
counter_element = FlutterElement(driver, counter_finder)
print(counter_element.text)
