The Google Home Developer Console provides a Test page where you can configure and run tests against your Matter integration using the Google Home Test Suite.
The Test Suite can be run on a set of devices that belong to a specific Matter project configuration. It is very important to run the Test Suite on your integration(s) to ensure that everything is working properly.
On the Test page, Matter integrations that are complete and ready to test are listed under Ready.
Matter integrations that have been tested are listed under Tested.
Type of test plans
There are two types of test plans:
Development test plans are used to test controlling devices using Matter. They are editable, but cannot be submitted for Matter certification.
Certification test plans are specifically for Matter certification, and are not editable.
