Steps to Set Up a Device Farm for Selenium Mobile Testing

To set up the device farm, you can make use of a cloud-based platform like LambdaTest. It is an AI-powered test orchestration and execution platform that lets you run manual and automated tests at scale with over 3000+ real devices, browsers and OS combinations.

This platform allows you to perform AI testing using an AI testing tool called KaneAI, offered by LambdaTest.

Below are the steps  that you need to follow to set up the device farm:

1. Account Setup

• Generate an Account: In order to access their cloud-powered device farm, you need to sign up on the LambdaTest platform.
• Obtain Credentials: From your LambdaTest account dashboard, get your unique access key and username.

2. Configure Test Scripts
3. Specify Desired Capabilities

In your Selenium testing script, define the desired capabilities to target particular devices. These capabilities comprise details such as:

• Mention OS: Specify the Operating System & version (e.g., iOS 16, Android 12).
• Specify Device Name: Mention the mobile device (for instance, iPhone 13, Samsung Galaxy S21).
• Define Browser Version: Define the browser & its version for testing web applications.

Use the set_capability technique in your Selenium script to configure such attributes.

Example snippet:

desired_capabilities = {

“platformName”: “iOS”,

“deviceName”: “iPhone 14”,

“browserName”: “Safari”,

“platformVersion”: “16”,

“build”: “Build_Name”,

“name”: “Test_Name”

}

1. Include LambdaTest

Integrate LambdaTest Selenium Grid URL & authentication description in the script. This incorporation ensures that your tests are implemented on LambdaTest cloud-based infrastructure rather than your local setting.

Replace the local Selenium Grid URL in the script with LambdaTest Selenium Grid URL:

https://username:accesskey@hub.lambdatest.com/wd/hub

• Replace the accesskey and username with your LambdaTest credentials.

Example setup in Python:

from selenium import webdriver

lt_options = {

“username”: “your_username”,

“accessKey”: “your_access_key”

}

driver = webdriver.Remote(

command_executor=”https://username:accesskey@hub.lambdatest.com/wd/hub”,

desired_capabilities=desired_capabilities

)

3. Application Upload for Native Tests

If you are testing a native mobile app:

• Upload the IPA (for iOS) or APK (for Android) file to the LambdaTest platform.
• Such a platform assigns an app URL that you can incorporate in your Selenium scripts to implement testing on the uploaded app.

4. Execute Testing

Implement your Selenium test script. The script will be implemented on the particular gadget & configuration within the LambdaTest device farm.
