Bug 80650 – [WebSocket] Add a layout test where server force to disable all extensions

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Takashi Toyoshima]

Currently, WebSocket extensions which WebKit implement are all enabled by default.
But this enabled extension list could be changed when WebKit support other extensions or rename existing extensions.
It means that the expectation of a test which verify extensions property depends on WebKit.
This is not good for embedder's unit tests.

So, I'd like to add a layout test where server pyewebsocket just omit all extensions and the extensions property returns empty string.

shouldBeEqualToString("ws.extensions", ""); ?

Oops, right.
I mistakenly overwrite the expectation.

It's hard to understand what are tested here with this result. At least we should show:

Check the value before opening the connection:
PASS ws.extensions is ""
PASS ws.extensions = "foo"; ws.extensions is ""
Check the value after opening the connection:
PASS ws.extensions is ""

I prefer shouldBeEqualToString("ws.extensions = 'foo'; ws.extensions", "");

> LayoutTests/http/tests/websocket/tests/hybi/extensions-expected.txt:7
>  PASS ws.extensions is ""
>  PASS ws.extensions is ""

I'd like to make the same comment with echo-with-no-extension-expected.txt.

Agreed.

nit: The comment is not helpful.

It's the same reason with compressed-control-frame.html, deflate-frame-invalid-parameter.html, deflate-frame-parameter.html, and handshake-fail-by-extensions-header.html.  They are skipped in Qt.

Thank you for the information, test will be inserted to that group.
