To enable running integration tests, a test GCP project must be provided.
There is a Google-maintained CI project, ansible-gcp-ci, that is used for this purpose. For any questions or modification to this project, please contact a maintainer who is employed by Google.
Since running the full set of integration tests requires the usage of GCP credentials which are stored as a secret, maintainers must verify that tests pass the integration test run that runs on push to the master branch after accepting a change.
