Specify devices using regular expressions (regex)

Specify devices using regular expressions on BrowserStack’s Private Devices

BrowserStack’s Dynamic Device Allocation (DDA) allows you to use regular expressions (regex) to specify device attributes, enabling flexible and efficient test execution.

Use regex to specify device attributes

You can use regex to select devices for testing instead of providing specific device models or OS versions. Based on the regex you provide, an available device is allocated from the device pool that matches your specifications.

Example: Using regex in browserstack.yml

Here’s an example of running a test on any Samsung Galaxy S series phone with an Android version between 10 and 12:

You can run tests on a wider set of devices. For example, to run tests on any Samsung Galaxy S series device refer to the following syntax:

userName: "<user name>"
accessKey: "<access key>"
app: bs://sample.app
platforms:
  - platformName: android
    deviceName: Samsung Galaxy S*
    platformVersion: "1[012]"
    dedicatedDevice: true
browserstackLocal: true
dedicatedDevice: true
buildName: browserstack-build-1
projectName: BrowserStack Sample

The following code snippet demonstrates running a test from a pool of two devices:

userName: "<user name>"
accessKey: "<access key>"
app: bs://sample.app
platforms:
  - platformName: android
    deviceName: Samsung Galaxy A52|Xiaomi Redmi Note 8
    platformVersion: "9.0|11.0"
    dedicatedDevice: true
browserstackLocal: true
dedicatedDevice: true
buildName: browserstack-build-1
projectName: BrowserStack Sample

If you are using the legacy mode of integrating your test suite, refer to DDA App Automate Legacy.
