Hi! I came across another interesting issue while writing tests for my
Restlet app. This time it involves using Selenium, which talks to my app
over HTTP.
Because it's an automated test, I don't really care what port something is
running on, and I don't want the test to fail because a hard-coded port
number is already in use. Happily, a port number of zero means that the OS
should just pick an arbitrary port. I would thus expect code like this to
work:
Server server = new Server(Protocol.HTTP, port, new MyApp());
server.start();
String root = "http://127.0.0.1:"; + server.getPort() + "/";
Selenium browser = new DefaultSelenium(SELENIUM__SERVER,
SELENIUM_PORT, BROWSER, root);
It comes close, but doesn't totally work. My app does indeed start up on
what InetSocketAddress calls an ephemeral port. However, the Server object
never learns that port number; it assumes that the port assigned is the
port requested.
I was trying to figure out a reasonable patch for this. I can see two
approaches.
One would be to type the helper as a ServerHelper, add getAddress() and
getPort() methods to that, and then delegate those methods on Server to
the ServerHelper.
The other is to have the StreamServerHelper stuff the address and port
information back into the Server once the bind completes. That would
involve touching less code, but would introduce a method or methods on
Server's public interface that I don't like much.
Any suggestions on how to proceed?
Thanks,
William
