Failing tests need access to secrets not available for external PRs.

Thanks for agreeing to do this guys - by the way, when does it appear in a build so I can try it for real in my app in question?

It's already available in the release-candidate branch, so if you change your Launchpad dependency in the docker image (the FROM part) and use release-candidate instead of v5 you can test it. I will probably merge these changes to the v5 and release a new version once the dry run PR is ready and merged.
