The Google Home Test Suite is a web application that allows you to self-test your smart home Action. The Test Suite automatically generates and runs test cases based on the devices and traits associated with your account. When you complete the tests, you can view the test results or fill in the submission form to submit the test results to Google.
The tests executed by the Test Suite include, but are not limited to, the following:
Verifies that the QUERY intent is implemented for your device and its results match Report State results.
You can launch the Test Suite tool by clicking the button below:
Self-test your Action
The following section describes how to run the Test Suite on your device and smart home Action project. The Test Suite requires you to sign in so that it can inspect devices in your Google Home Graph and send commands directly to Google Assistant.
To self-test your Action, follow these steps:
- In your web browser, open the Test Suite.
Sign-in to Google using the top-right corner button.
Configure the Project Details:
- In the Project ID field, enter the project identifier for your smart home Action.
- Click Next.
Configure Test Settings:
- If certifying your smart home Action, leave the default Report State/Request Sync Timeout value unchanged. However, for testing, you may change the timeout value if your agent takes more time to report state to Home Graph.
If certifying your smart home Action, make sure the Test Request Sync option is enabled—during testing, you will be prompted to add, update, or remove a device and check if the device list has changed in Home Graph. Change actions take place through the integration you are testing. Your integration under test must always have at least one device attached to the agent user.
If you are using a Scene trait, select Test Scene trait.
If you are running the test suite for Local Home devices, select Supports Local Home SDK.
- Select Local Fulfillment or Seamless Setup.
- Click Supports Local Query if the device can handle QUERY intent locally.
Perform a Test Run and view results:
- Click Next to start running tests. The interface shows the devices and traits that are being tested.
View the Results & Submission page:
- Once the tests are complete, click Next to view the results.
The test results include the number of tests passed and failed, and a final score indicating percentage of passes.
Account linking validation test
Account linking plays an important role in the Google smart home ecosystem. The account linking validation test in Test Suite checks your OAuth service for potential issues.
Access token validation test
Access tokens returned from your token exchange endpoint are tested to ensure they have a valid format and are returned with a valid refresh token.
|Check if access token is JWT format||Google account linking does not recommend JWT format access tokens. If a
JWT format is found, the following warning is displayed:
|Check expirable access token has refresh token.||A refresh token must be provided when the access token is expirable. This test will fail if no refresh token is found.|
Refresh token validation test
Refresh tokens are tested to ensure your token exchange endpoint properly exchanges them for new access tokens.
|Refresh token with invalid refresh token, checking partner response.||Your server should return an HTTP 400 Bad Request error with
|Test if access token has been updated after token refresh.||New access tokens should be returned in response to refresh token requests. If your server provides the same access token, the test case will fail.|
|Check if the unexpired access token is still valid.||The access token expiry time will be displayed.|
|Check if refresh token has been rotated during refreshing.||We check if refresh tokens are changed after a refresh token request. If the refresh token changes, your server should only invalidate an old refresh token after a new refresh token has been used, to prevent race conditions that may break a user's account linking. The test will fail if you invalidate the old refresh token before the new one is used.|
The following table lists some common error messages you may encounter and the suggested way to resolve them.
|Error Message||How to Resolve|
|HomeGraph API has not been used in project <_id_> before or it is disabled||Make sure that you have enabled the HomeGraph API.|

Submit test results
Your Test Suite results must pass 100% of tests before submitting your certification form. If you have any traits that require manual testing, you should still run the Test Suite tool and attach the result even if it has not passed at 100%.
To submit your test results and certify your smart home Action, follow these steps:
- After you receive your test results and you are ready to certify your smart home Action, click Submit in the Test Suite tool.
- Click the DOWNLOAD TEST RESULTS button to retrieve your test results.
- Click the GO TO SUBMISSION FORM to submit the test results to Google.
Fill out all of the required fields, then click Submit.
