Available devices in Test Lab

Test Lab lets you test your app on a wide variety of different devices and Android versions. There are a few ways to see which devices are available:

  • Firebase console: If you're running tests from the Firebase console, you can see a list of available devices during the Select dimensions step of the Run a test workflow.

  • gcloud CLI: To see a list of available devices from the Google Cloud CLI, use the following command:

    gcloud firebase test android models list
  • Google APIs Explorer: You can even look up the devices directly, without a Firebase project or the gcloud CLI, using the Google APIs Explorer.

Device stability indicator

Test Lab indicates devices that are experiencing degraded stability in the Firebase console and Google Cloud CLI with a Reduced Stability indicator. Devices that have been labeled with the Reduced Stability indicator have returned higher rates of inconclusive results for a prolonged period of 30 days or more. This feature helps you better choose devices for your use case by letting you know if the stability of a test device is degraded.

View device stability in the Firebase console

You can view device stability in the Firebase console when you're setting up a new test for a specific device.

To view device stability, follow these instructions:

  1. Open the Test Lab page in the Firebase console.

  2. Select Run a test and then select a test type.

  3. Upload your app binary.

  4. On the Select dimensions step, click Customize.

  5. Choose one or more devices to run your test on. Depending on device stability, you might see a Reduced Stability label next to the selected devices.

  6. Run your test.

View device stability in the Google Cloud CLI

You can view device stability in the gcloud CLI for a specific device when you're setting up a new test.

To view device stability, follow these instructions:

  1. Download the latest Google Cloud SDK and follow the instructions.

  2. Run one of these commands: gcloud firebase test android models list or gcloud firebase test android models describe MODEL_ID

If a test device is experiencing degraded stability, you can see the reduced_stability tag in the TAGS column listing the versions that are affected.

Device capacity

Test Lab provides aggregated mobile device capacity information through the Firebase console and Firebase CLI. Device capacity is the aggregated number of online devices in Google's mobile device lab. This feature helps you ensure that there are enough devices in our device lab to run your tests more efficiently. Device capacity is measured as High, Medium, and Low.

Tests running on any device capacity level may take longer due to the following factors:

  • Traffic, which affects when the test starts. To check if there are reported outages or failures, see the Firebase status dashboard.
  • Device or infrastructure failures, which can happen at any time and affect how long the test takes to run.

The following table describes the types of device capacity and provides recommendations about when to use each capacity type:

Capacity Description Recommended use
High capacity The Test Lab device catalog contains many devices. Use when you are running a large number of tests.
Medium capacity The Test Lab device catalog contains a moderate number of devices. This capacity level is suitable for running most of your tests.
Low capacity The Test Lab device catalog contains few devices. While deprecated devices belong to the low-capacity group, not all low-capacity devices are deprecated. Use when you need to run a test on a specific device model and version. These tests are not suitable for test sharding. Due to low capacity, tests might take a long time to finish, especially if you invoke a large number of tests at the same time.
Note: Android virtual devices have variable capacity. The number of pre-booted virtual devices is based on typical recent usage, and can auto scale larger during periods of heavier usage.

View device capacity in the Firebase console

You can view device capacity in the Firebase console for a specific device when you're setting up a new test.

To view device capacity, follow these instructions:

  1. Open the Test Lab page in the Firebase console.

  2. Select Run a test and then select a test type.

  3. Upload your app binary.

  4. On the Select dimensions step, click Customize.

  5. (Optional) To filter devices by capacity level, follow these steps:

    1. Click the Filter icon.

    2. Select Capacity.

    3. Click the capacity level you want to filter by: Medium or High. To filter out any low-capacity devices, filter by both Medium and High.

    4. Click Apply.

  6. Choose one or more devices to run your test on. Depending on device capacity, you might see a Medium or High label next to the selected devices.

  7. Run your test.

View device capacity in the Google Cloud CLI

You can view device capacity in the gcloud CLI for a specific device when you're setting up a new test.

To view device capacity, follow these instructions:

  1. Download the latest Google Cloud SDK and follow the instructions. The version must be 417.0.0 or greater.
  2. Run one of these commands:
    gcloud firebase test android list-device-capacities
    or
    gcloud firebase test android models describe MODEL_ID

The output includes device capacity, model ID, model name, and OS version ID.

Deprecated devices and versions

Deprecated devices are available for at least one month before being removed from the Test Lab device catalog. Once a device is removed, Test Lab no longer runs test requests targeted at the device; those requests are marked as Skipped.
