LGTM when tests pass, but I am not sure why it doesn't like the min_passes param. Let me know if you want to pair to try to debug.

I'm seeing:

 ! [rejected]          iot-extra-flaky -> iot-extra-flaky (fetch first)
error: failed to push some refs to 'https://github.com/googlecloudplatform/python-docs-samples'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

@gguuss it's because I merged master into this to keep it up to date and re-trigger the CI earlier :)
