+// Basic idea behind core test runner is to modify core tests as little as
+// possible. That's why we start up node-http-proxy here instead of embeeding
+// this code in tests.
+//
+// In most cases only modification to core tests you'll need is changing port
+// of http client to common.PROXY_PORT.
+//

+var path = require('path'),

+

+proxy.listen(common.PROXY_PORT);
