The lack of coverage was due to:
* An unused function that was never used anywhere.
* get_commit_status_changed_body was using a regex where it didn't
really need to use one. And there was an if statement that
assumed that the payload might NOT contain the URL to the commit.
However, I checked the payload and there shouldn't be any instances
where a commit event is generated but there is no URL to the commit.
* get_push_tag_body had an `else` condition that really can't happen
in any payload. I verified this by checking the BitBucket webhook
docs.
This directory contains scripts that are used in building, managing,
testing, and other forms of work in a Zulip development environment.
Note that tools that are also useful in production belong in
scripts/ or should be Django management commands.
