If we're not passing in expected_topic or expected_message
to check_webhook, it's better to just call send_webhook_payload,
since we'll want to explicitly check our messages
anyway.
This preps us to always require those fields for
check_webhook, which can prevent insidious testing no-ops.
This forces us to be a bit more explicit about testing
the three key values in any stream message, and it
also de-clutters the code a bit. I eventually want
to phase out do_test_topic and friends, since they
have the pitfall that you can call them and have them
do nothing, because they don't actually require
values to be be passed in.
I also clean up the code a bit for the tests that
have two new messages arriving.
Almost all webhook tests use this helper, except a few
webhooks that write to private streams.
Being concise is important here, and the name
`self.send_and_test_stream_message` always confused
me, since it sounds you're sending a stream message,
and it leaves out the webhook piece.
We should consider renaming `send_and_test_private_message`
to something like `check_webhook_private`, but I couldn't
decide on a great name, and it's very rarely used. So
for now I just made sure the docstrings of the two
sibling functions reference each other.
The "EXPECTED_" prefix and "_EVENTS" suffix
usually provided more noise than signal.
We also use module constants to avoid the "self."
noise. It also makes it a bit more clear which
constants actually have to be in the class (e.g.
"FIXTURE_DIR_NAME") to do their job.
