Running tests together with Appium

When it comes to mobile automation testing, there are many different choices for a test tool. One popular option is Appium, an open source project which enables running automated tests on both Android and iOS devices.

No registration is needed and you can either download the latest version of the standalone app here, or you can install the cli version by running:

> brew install node      # get node.js
> npm install -g appium  # get appium
> npm install wd         # get appium client
> appium &               # start appium

We’ve created an example python project which can be found here which hopefully can get you started on your own projects. Using it will also automatically install the requirements needed for running the tests. More details about it below.

Why use Appium together with AltUnity Tester

There’s a couple of reasons / scenarios for which you would want to use both of these frameworks:

  • By itself, AltUnity Tester cannot launch an app on a device. If you want to run tests in a pipeline, or by using cloud services, you can either create a script which will start your app, or you can use Appium before the tests execution;

  • AltUnity Tester cannot perform some types of actions, such as interacting with any native popups your app might have, or putting the app in the background and resuming it. In any of these cases you can use Appium to do the things that AltUnity Tester can’t.

AltUnity Tester with Appium example

After you cloned our example project, there are a couple of things you need to check before running the tests:

  • For Android you need to have Android SDK version 16 or higher installed on your machine;

  • For iOS you need XCode with Command Line Tools installed (will only work on Mac OSX);

  • Your mobile device needs to have developer mode enabled and be connected via USB to the machine running the tests.

Running the tests

  • For Android you can just run the script run-tests_android.sh

  • For iOS, you first need to export IOS_UDID=<your-device-udid> then run the script run-tests_ios.sh

Note

To find out an iOS device UDID you can go to Finder, click the device in the sidebar and click the info under the device name to reveal the UDID

The script will install any requirements that are missing from your machine (except Android SDK and XCode CLT), then run a basic test scenario:

  1. The app will be started by Appium;

  2. AltUnity Tester will ensure it’s initially loaded;

  3. Appium will put the app in the background for a couple of seconds, then resume it;

  4. AltUnity Tester will check if the app was resumed successfully.

Note

Please observe the following about the setup method in base_test.py:

  1. A minimum amount of desired capabilities have to be set in order for Appium to work. More details about desired capabilities can be found in the official Appium documentation

  2. The Appium driver needs to be created before the port forwarding needed by AltUnity Tester is done. This is because Appium clears any other port forwarding when it starts.
