Test biometric authentication on mobile devices with Espresso framework

Simulate touch ID, fingerprint, and face ID authentication flows on real Android and iOS devices during your Espresso test executions.

Most mobile devices today support biometric hardware sensors to authenticate a device owner’s identity. BrowserStack enables you to test biometric authentication, such as touch ID, fingerprint sensor, and face ID, on a BrowserStack mobile device with the Espresso framework.

Supported OS and version

Enable biometric authentication

Use the BrowserStack parameter enableBiometric and set it to true in the REST API request to enable biometric authentication for your Espresso test session.

This ensures your app undergoes Sensor Instrumentation, a process that supports your app’s interaction with biometric mobile sensors on BrowserStack real devices.

Example request:

curl -u "YOUR_USERNAME:YOUR_ACCESS_KEY" \
-X POST "https://api-cloud.browserstack.com/app-automate/espresso/v2/build" \
-d '{
"enableBiometric": "true",
"devices": ["Samsung Galaxy S8-7.0"],
"app": "bs://f5L3azt9pLzE995f49376eb1fa3c284dc321f8d",
"testSuite": "bs://6eb1fa3c284ddbe9971b2d1aee0d52943b9c081"}' \

Test your app using biometric authentication

Prerequisite: Enable biometric authentication for your app.

To test your app, follow these steps:

1. In your app, trigger the biometric authentication workflow.
2. To interact with the Biometric Authentication prompt, write test scripts that click Pass, Fail, or Cancel to test authentication success or failure scenarios. BrowserStack App Automate closely mimics the biometric authentication behavior on real devices. Based on your platform, refer to this table to understand the behavior:
