I expect this PR to make the acceptance test fail -- I won't make it pass until I see it fail first.

acceptance tests don't run against PRs as they create real resources. the CONTRIBUTING guide outlines how to get acceptance tests run locally.

hit me up if you need a hand getting these to run and fail as you expect.

OK, I was hoping I wouldn't have to create resources as I've never used terraform and wouldn't know how to delete them after.

Also, this PR is 1380, but .changelog/1380.txt already exists -- any suggestions for how to resolve that conflict?

If you write tests and have the Delete method implemented in the resource, Terraform calls this before exiting the test so it should clean up automatically.

Apologies, that was me testing and ended up committing the wrong ID. I've resolved this now.

this PR is good to go however, we do have permadiff to address down the track
