Test results for a Matter integration version must be
submitted to Google as part of the [Works with Google Home (WWGH)
Certification](https://developers.home.google.com/matter/certification) process. Test results must also be
submitted before a [Field Trial](https://developers.home.google.com/matter/field-trial.md.txt) may begin.

> [!NOTE]
> **Note:** If you used the **CSA Interop test** option for a Matter integration, you only need to submit the Connectivity Standards Alliance (Alliance) test results for certification.


<br />

> [!IMPORTANT]
> **Important:** Starting in 2026, we will be transitioning to using the Connectivity Standards Alliance (Alliance) Interop Test Lab results for certification. See the [Alliance Interop Test Lab transition](https://developers.home.google.com/matter/csa-interop-test-lab) page for more details.

When a test suite has completed running, you have the option to submit the
results. Click **Submit** below the **Logs** section to submit.

**If the Matter device is a
[Matter Bridge](https://developers.home.google.com/matter/supported-devices.md.txt#bridges),
Google Home Test Suite results are required for all the devices listed
in the Alliance Certification document.**

For products certified under the **Product Family** or **Portfolio**
certification programs, it is acceptable to upload the Alliance
ITL report for the parent product when submitting a certification review for a
child product. In addition to the parent product's Alliance ITL
report, developers must provide documentation demonstrating the relationship
between the parent and the child products. This documentation should include
the Alliance certification record showing the certification IDs
for both the parent and child products.

Once submitted, you'll be returned to the **Test** page in the
Google Home Developer Console. The integration version with the submitted test now
appears in the **Tested** section.

> [!IMPORTANT]
> **Important:** Make sure the software versions are the same versions used for the Alliance certification.

## Justification for failed tests

A test suite with failed tests may be submitted if a valid justification is
provided.

For a failed test:

1. Open the failed test by clicking on the icon.
2. In the box, enter a detailed justification for the test failure, and why the integration version should still be considered for certification, despite the failure.
3. Click **Post** to save the justification.

Use the **Edit justification** button to edit the justification later as
needed.
