Since FIXTURE_DIR_NAME is the name of the folder that contains the view
and tests modules of the webhook and another folder called "fixtures" that
store the fixtures, it is more appropriate to call it WEBHOOK_DIR_NAME,
especially when we want to refer to the view module using this variable.
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.
