Failing unit test in Node 10+ (connection timeout)

[jancurn]

The unit test of the https-proxy-agent package fails on Node 10+:

  1) HttpsProxyAgent "http" module should work over an HTTP proxy:
     Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.
  
  2) HttpsProxyAgent "http" module should work over an HTTPS proxy:
     Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.
  
  3) HttpsProxyAgent "after all" hook:
     Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

I suspect this is related to the following change introduced in Node 10: nodejs/node#19981

Unfortunately, this issue makes it impossible to use web sockets over HTTPS proxy, since that depends on https-proxy-agent. For example, unit tests of https://github.com/apifytech/proxy-chain fail for this reason (see https://github.com/apifytech/proxy-chain/blob/master/test/server.js#L612)

For a reference: As a workaround, rather than using ws + https-proxy-agent package to connect web socket via HTTPS proxy, one can use the faye-websocketpackage.
