Does this look right in the log starting with lower case?

Not sure if this tests enough. Isn't the purpose to verify that the connection is never established? This just verifies that it's dropped, perhaps only eventually.

Also, failing as timeout isn't always understood to be a legitimate failure in practice.

I'll capitalize.

I committed this separately in http://trac.webkit.org/r283574

This is what it looks like at this API level when a connection is never established.  I'll change this to make sure event is always equal to XPC_ERROR_CONNECTION_INTERRUPTED to make sure that nothing else happens.

I agree that it's not great to have the failure mode be a timeout, but I think that's how this test needs to be.
