cherrypy when to know that the server has started

I am trying to write some unit tests for a small web service written with Cherrypy and I am wondering what's the best way to figure out that the server ha开发者_JAVA技巧s started, so i don't get connection refused if I try to connect too early to the service ?

I got it figured out:

cherrypy.engine.start(); cherrypy.server.wait() it's the way to go.

Otherwise, I think you can get away with some tricks with cherrypy.server.bus.states
