Multi-Device Testing on Real Devices
Multi-Device Testing enables you to run multiple devices simultaneously in a single App Live session, allowing you to validate your application across different devices and OS versions faster and more efficiently. This approach simplifies cross-device testing by bringing multiple devices into a single session.
TestMu AI allows you to run up to 6 devices at a time within a single session, depending on your plan’s parallel limit. You can choose different applications for each device or test multiple versions of the same app concurrently, all from a single interface, without the need to start separate sessions.
This feature is available exclusively with the Real Device Plus Live Plan.
To unlock this feature, purchase or upgrade to the required plan. If you need assistance, please contact your TestMu AI support representative, reach out to our [24×7 Chat Support], or email us at support@testmuai.com.
Use Cases
- Cross-Device Functional Testing: Validate app functionality across multiple devices simultaneously.
- UI Consistency Check: Ensure your app displays correctly on different screen sizes and resolutions.
- Multi-App Workflow Testing: Test interactions between multiple apps in a single session.
- OS Version Verification: Verify app behavior across different OS versions.
- Faster Regression Testing: Reduce testing time by running multiple devices together.
Multi-Device Testing Workflow
Step 1: Open a Real Device Session
Log in to your App Live Dashboard, upload your app, and select a real device (Android or iOS).
Step 2: Add Devices Using Multi-Device Option
Once the session is open, click on the add device option to add more devices. You can set up to 6 devices per session and select the device and application for each.

Step 3: Apply Multi Device Control Settings
Once devices have been added to the session, you will see an option called Multi-Device Control. This feature allows you to apply common actions and settings across all connected devices simultaneously, reducing repetitive steps and ensuring consistent configurations.
