What are the conditions that url and latestReadyRevisionName will be set? I can see the other 2 fields in the status of our existing tests, but not those.

@rileykarson I guess it's set after the app becomes ready. CloudRun deployments are somehow asynchronous (like kubectl apply), these fields are blank on first apply. If you run terraform apply or terraform refresh after the app becomes ready, you can see actual value of them.
(Similarly, all of status.conditions[*].status is "Unknown" on a first apply, but becomes "True" on next refresh).

I'm not thrilled about fields that get set out of band like that, but that's more a gripe with the API than anything else. Filed hashicorp/terraform-provider-google#4335 for an improvement to Cloud Run behaviour.
