This page provides troubleshooting help and answers to frequently asked questions about running tests with Firebase Test Lab. If you can't find what you're looking for or need additional help, join the #test-lab channel on Firebase Slack or contact Firebase support.
Troubleshooting
When you select a device with a high capacity level in the Test Lab catalog, tests may start faster. When a device has low capacity, tests might take longer to run. If the number of tests invoked is much larger than the capacity of the selected devices, tests can take longer to finish.
Tests running on any level device capacity level may take longer due to the following factors:
- Traffic, which affects device availability and test speed.
- Device or infrastructure failures, which can happen at any time. To check if there is a reported infrastructure for Test Lab, see the Firebase status dashboard.
To learn more about device capacity in Test Lab, see device capacity information for Android and iOS.
Frequently asked questions
Firebase Test Lab offers no-cost quotas for testing on devices and for using Cloud APIs. Note that the testing quota uses the standard Firebase pricing plan, while the Cloud API quotas do not.
Testing quota
Testing quotas are determined by the number of devices used to run tests. The Firebase Spark plan has a fixed testing quota at no cost to users. For the Blaze plan, your quotas might increase if your usage of Google Cloud increases over time. If you reach your testing quota, wait until the next day or upgrade to the Blaze plan if you are currently on the Spark plan. If you are already on the Blaze plan, you can request a quota increase. For more information, see Testing quota.
You can monitor your testing quota usage in the Google Cloud Console.
Cloud Testing API quota
The Cloud Testing API comes with two quota limits: requests per day per project, and requests per every 100 seconds per project. You can monitor your usage in the Google Cloud Console.
Cloud Tool Results API quota
The Cloud Tool Results API comes with two quota limits: queries per day per project, and queries per every 100 seconds per project. You can monitor your usage in the Google Cloud Console.
Refer to Cloud API quotas for Test Lab for more information on API limits. If you've reached an API quota:
Submit a request for higher quotas by editing your quotas directly in the Google Cloud Console (note that most limits are set to maximum by default), or
Request higher API quotas by filling out a request form in the Google Cloud Console or by contacting Firebase support.
From your backend, you can determine if traffic is coming from Firebase-hosted test devices by checking the source IP address against our IP ranges.
Test Lab does not work with VPC-SC, which blocks the copying of apps and other test artifacts between Test Lab's internal storage and users' results buckets. At the moment, a feature request has been filed to add VPC-SC support in a future release.
While some of these items are on our roadmap, we're currently unable to provide commitment to supporting these testing and app development platforms.
