Bug 123205 – Adding mock class to test RTCDataChannelHandler

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Thiago de Barros Lacerda]

Now RTCPeerConnectionHandler-datachannel LayouTest can run properly.
Also updated the expected file, removing the reliable property check (which was removed in the spec)

I would say "Existing tests updated" instead.

Are these "Copied from" comments correct?

These should all be virtual.

Nit: it may be slightly more space efficient to have the "short" and "bool" members last.

Git thinks that I copied them, maybe because of its similarity check. But I didn't not copy. Should I remove them?

Why? The class is final, so no class can use it as superclass and override its methods.

  I would remove the comments because they are incorrect.

By looking at the webkit source, I could notice that they put the virtual keyword anyway, maybe is it a style? Should I add virtual?

I think so. It is slightly pedantic, but I think it makes it more obvious and it what is typically done in WebKit.
