A few inline comments as a first pass, but looking good so far.

There are a couple of things that can still be improved I think, if you still have some forces ;)

• the fact that we return 201 on errors. See my comment https://github.com/mozilla/jira-bugzilla-integration/pull/31/files#r838330014
• the fact that we refetch/parse the bug in the action code https://github.com/mozilla/jira-bugzilla-integration/pull/31/files#r838340107
• the way jira and bugzilla are mocked in tests

We've never been so close ;)

Thanks again @leplatrem for your review; I've added some comments--and willing to further adjust, but I think most of the comments have been resolved in the most recent commit.

💯

The 202 status is fine yes. What was wondering me most was the catch all of action errors.

The only thing left is the logging. I'm a little bit scared to have requests ignored silently, especially for the first cycles of deployment.

@leplatrem I went through and made some changes based on your most recent comments.

I tried to add the suggested helper as an injected method in the bugzilla client returned from the get_bugzilla call, but something seemed off with that approach.
