* Python 2 fix for host address
This is a copy of
57051a48cd
for the Websocket protocol.
In Python 2, Twisted returns a byte string for the host address, while
the spec requires a unicode string. A simple cast gives us consistency.
* Test suite for websocket tests
This commit
* introduces some new helpers to test the Websocket protocol
* renames the old ASGITestCase class to ASGIHTTPTestCase, and
introduces a test case for testing Websockets
* moves some helper methods that are shared between HTTP and Websockets
into a mutual base class
* uses the new helpers to simplfiy the existing tests
* and adds a couple new tests.
* add websocket timeout and websocket connetion timeout to Cli. Add support for infinite time to websocket timeout and websocket connection timeout
* change test
* Fix: Always call Request.write()
The spec says 'content' is an optional key, defaulting to b''.
But before this commit, if 'content' wasn't specified, Request.write()
was not called. In conjunction with setting 'more_content' to True,
this would result in nothing being written on the transport. If
'content' was set to b'' instead, the HTTP preamble and any headers were
written as expected. That smells like a bug, so I'm making sure we're
always calling Request.write().
* Require status key in first message to response channel
Previous to this commit, it was possible to not pass in a 'status' key.
This would result in any passed in headers being ignored as well.
Instead of relying on user data ('status' being present or not), this
commit now enforces that the first message to a response channel is
indead a HTTP Response-style message, and hence contains status. It will
complain loudly if that isn't the case.
* Helper for getting HTTP Response for a given channel message
To test Daphne's message-to-HTTP part, we need an easy way to fetch the
HTTP response for a given response channel message. I borrowed the
approach from Andrew's existing code. I feel like we might be able to do
with less scaffolding at some point, but didn't have time to
investigate. It's good enough for now.
* Add assert method to check a response for spec conformance
Similarly to the method for checking HTTP requests for spec conformance,
we're adding a method to do the same for HTTP responses. This one is a bit
less exciting because we're testing raw HTTP responses.
* Add Hypothesis tests for HTTP responses
Similarly to what I did for HTTP requests, this commit adds a couple
test that try to check different parts of the ASGI spec. Because going
from message to HTTP response is more straightforward than going from
HTTP request to channel message, there's not a whole lot going on here.
