Selenium 2 Grid - Knowing which node your test is using

Question

Is it possible to know which node the selenium grid hub assigned to your test? My tests need to talk to other services on the node machine in order to perform configuration

Answer 1

String hub = "grid_server_host"; //IP or hostname of GRID

int port = 4444; // port no.

HttpHost host = new HttpHost(hub,port);

DefaultHttpClient client = new DefaultHttpClient();

String url =  host + "/grid/api/testsession?session=";

URL session = new URL(url + ((RemoteWebDriver) webdriver).getSessionId());

BasicHttpEntityEnclosingRequest req;

req = new BasicHttpEntityEnclosingRequest("POST", session.toExternalForm());

org.apache.http.HttpResponse response  = client.execute(host,req);

JSONObject object = new JSONObject(EntityUtils.toString(response.getEntity()));   

String proxyID = (String) object.get("proxyId");

String node = (proxyID.split("//")[1].split(":")[0]);
