It's failed on all platform instead. Update the summary properly.

Attachment: (v1) Patch: Fix failures in dom/network/tests/ with comformant Promise handling.

I'd like to fix it from the implementation instead of the test case because, from the API perspective, it shall be reasonable to close a socket immediately without an error right after it was opened successfully:

BTW, TCPSocket seems not part of HTML standard and the only use case is only available in ppapi:

(Ask for your review of this change because the owner of this module seems no longer available.)

Try result looks fine with/without the new microtask scheduling:

Interesting. Hmm, did I have this in some of my patches and forgot to upload.

Here is what you did in your wip patch:
   // -- Client closes the connection
   clientSocket.close();
   is(clientSocket.readyState, 'closing',
      'client readyState should be losing immediately after calling close');
 
+  is((yield clientQueue.waitForEvent()).type, 'error',
+     'The client should get a error event.');
   is((yield clientQueue.waitForEvent()).type, 'close',
      'The client should get a close event when it closes itself.');
