Custom Device Lab with Espresso
Execute Espresso tests on devices on the Custom Device Lab for native Android app testing.
To run Espresso tests on Custom Device Lab hosted on BrowserStack’s private cloud, use the same REST API endpoint and workflow described in the Espresso documentation, with a few additional parameters specific to Custom Device Lab.
Prerequisites
-
Ensure you have a BrowserStack Username and Access Key. You can obtain your
usernameandaccess keyfrom the Account & Profile section on the dashboard.
If you have not yet created an account, sign up for a Free Trial. -
Upload your application and test suite.
Key differences from public cloud
The overall workflow is the same, but you need to include the following additional parameters in your REST API request to target Custom Device Lab.
Sample API request using Custom Device Lab to execute your test
The table below explains the parameters used in the REST API request:
| Parameter | Required | Description |
|---|---|---|
dedicatedDevice |
Yes | Set this to true to indicate that the test should run on a Custom Device Lab device. This tells BrowserStack to route the test to your Custom Device Lab device pool instead of the public cloud. |
deviceId |
Yes | The deviceId is the same as UDID. It is a unique identifier of the Custom Device Lab device on which you want to run the test. You can retrieve this ID from your Custom Device Lab device pool dashboard or through your account representative. |
devices |
Yes | An array specifying the device name and OS version in the format "deviceName-deviceOSVersion" (e.g., "Samsung Galaxy S21-11.0"). While this field is optional when deviceId is provided, it can be useful for logging or organizational purposes. |
