Webdriver.IO + Appium for Mobile Testing

General System Requirements

Node JS

We need node js to download Appium beta version & drivers easily.

• Download Node Js depending on your operating system.

Java JDK & JAVA_HOME variable

• Open JDK
• JAVA_HOME setup for Windows
• JAVA_HOME setup for Mac

I Tested the following steps on MAC OS Monterrey:

• Installed Adopted Open JDK with Homebrew
• To return where was the SDK installed I used the command:

    /usr/libexec/java_home

• If you want to check the java version:

    /usr/libexec/java_home -V

• Open the zshenv file to insert the JAVA_HOME variable (i):

    vim ~/.zshenv

• Enter the environment variable and save the vim session (:wq!):

    export JAVA_HOME=$(/usr/libexec/java_home)

• Source and apply the changes in the system:

    source ~/.zshenv

• You can check if it was set correctly running the command:

    echo $JAVA_HOME

• It should return something like:

    /Library/Java/JavaVirtualMachines/adoptopenjdk-16.jdk/Contents/Home

Android Setup

Android Studio & ANDROID_HOME variable

• Android Studio
• ANDROID_HOME setup for Windows
• ANDROID_HOME setup for Mac

Tested the following steps on MAC OS Monterrey:

• Android studio on Mac can be located at:

    * cd /Users/[USER]/Library/Android/sdk

• We need to add a reference to a couple of folders inside of that SDK
  • Tools & Platform Tools
• Open the zshenv file to insert the ANDROID_HOME variable (i):

    vim ~/.zshenv

• Enter the environment variables and save the vim session (:wq!):

    export ANDROID_HOME="/Users/[USER]/Library/Android/sdk"
    export PATH=$ANDROID_HOME/platform-tools:$PATH
    export PATH=$ANDROID_HOME/tools:$PATH

• Source and apply the changes in the system:

    source ~/.zshenv

• You can check if it was set correctly running the command:

    echo $ANDROID_HOME

• It should return something like:

    /Users/[USER]/Library/Android/sdk

• With this configured you can access the command Android Debug Bridge

    adb

IOS Setup

1. Install XCode from the MacOs App Store
2. Install XCode Command line tools

    xcode-select --install

• Make sure it is installed correctly using the following command:

    xcode-select -p

• It should return something like(may defer from your OS version):

    /Applications/Xcode.app/Contents/Developer

3. Install Carthage(It is a simple dependency manager for macOS and iOS, created by a group of developers from GitHub).

    brew install carthage

Download Appium Inspector

In order to find the correct locators to map elements, you will need to have this tool installed in your computer.

• Appium Inspector Releases

For this project you can use the following configuration:

Android Desired Capabilities(Example)

IOS Desired Capabilities(Emulator - App)

Install Apium

Appium is an open source test automation framework for use with native, hybrid and mobile web apps. It drives iOS, Android, and Windows apps using the WebDriver protocol.

• Install Appium from the official documentation
• Install Appium 2 by Node JS(Beta):

    npm install -g appium@next

Check the appium version using

    appium -v

Appium Doctor

To check if your OS meets the appium requirements, install this node package.

• Appium Doctor Package Install it using the command

npm install appium-doctor -g

And then use the library:

appium-doctor

Appium drivers

If you want Appium to work correctly, you need to download and have the android/ios driver in your system. Run the commands:

appium driver install xcuitest
appium driver install uiautomator2

Check the installed drivers using

appium driver list

Sample applications

Sample Application that you can use:

SauceDemo Hybrid App - React Native) - (Framework is configured to use this one)

Sauce Labs Native Sample Application

WebdriverIO Demo App for iOS and Android

Important Note: For IOS you are going to need an app build to run it in simulators, but an .IPA file to run it in real devices. It required additonal desired capabilities, and you can see which ones in the next article: Appium XCUITest Driver Real Device Setup

Setup WebDriverIO

1- Run the command to create the package.json & continue with the installation process

    npm init wdio .

2- Using the WDIO Configuration Helper select the options you want to select. In my case I decided to use:

• On my local machine
• Mocha
• No compiler
• Spect Location: Default
• Do you want WebDriverIO to generate some test files?: No
• Reporter: Spec
• No Plugin
• Service: Appium
• Base URL: Default
• NPM Install: Yes

3- Add your tests at

'./[yourProject]/specs/**/*.js'

4- Configure the app route at wdio.conf.js

• Declare where it is going to be located

const projectPath = require('path')
const androidAppPath = projectPath.join(process.cwd(), "app/android/Android-MyDemoAppRN.1.3.0.build-244.apk")
const iosAppPath = projectPath.join(process.cwd(),"app/ios/MyRNDemoApp.app");

• Set up the capabilities for Android(Emulator sample)

capabilities: [{
        platformName: 'Android',
        "appium:device-name": 'Pixel 4 API 30(R)',
        "appium:platformVersion": "11.0",
        "appium:automationName": "UIAutomator2",
        "appium:app": androidAppPath,
        // "appium:appWaitActivity": "com.swaglabsmobileapp.MainActivity"(For OLD swaglabs app)
    }]

• Set up the capabilities for Android(Emulator sample)

capabilities: [{
        platformName: 'IOS',
        "appium:device-name": 'iPhone 13 Pro Max',
        "appium:platformVersion": "16.0",
        "appium:automationName": "XCUItest",
        "appium:app": iosAppPath,
    }]

• Install Appium in your project

    npm install --save-dev appium@next

• Check if the drivers are still available, if not install them again:

appium driver list

appium driver install xcuitest
appium driver install uiautomator2

• Run your scripts using

npx wdio

Setup WebDriverIO

if you want to run this project:

1- Install all the system requirements

2- Clone the project

3- Run: npm i

4- Download the android app and place it under app/android or app/IOS

5- npm run wdioIOS/wdioAndroid
