This improves test coverage for a lot of our webhooks that relied
on ad-hoc methods to handle unexpected event types.
Note that I have deliberately skipped github_legacy, it isn't
advertised and is officially deprecated.
Also, I have refrained from making further changes to Trello, I
believe further improvements to test coverage should be covered
in separate per-webhook commits/PRs.
These are the straightforward ones.
Note that there is a line in zerver.lib.test_classes.build_webhook_url
that lost test coverage. That's because most of our tests test using
stream messages so the webhook URLs being tested always have a query
parameter. So the line that accounts for there being no query
parameters never gets called, which is fine, but we should still
keep it.
This commit:
* Removes the unnecessary screenshot. The UI is intuitive enough
and standalone instructions should suffice.
* Rearranges the instructions into 4 steps.
* Makes the wording more explicit.
This commit migrates all webhooks to use check_send_stream_message
instead of check_send_message. The only two webhooks that still
use check_send_message are our yo and teamcity webhooks. They
both use check_send_message for private messages.
Previously, api_key_only_webhook_view passed 3 positional arguments
(request, user_profile, and client) into a function. However, most
of our other auth decorators only pass 2 positional arguments. For
the sake of consistency, we now make api_key_only_webhook_view set
request.client and pass only request and user_profile as positional
arguments.
All webhook fixtures in zerver/fixtures/<webhook_name> have now
been moved to dedicated webhook-specific directories under
zerver/webhooks/<webhook_name>/fixtures, where <webhook_name> is
the name of the webhook.
