Selenium Java process called from c# not starting properly on CCNET build server

Question

Hi, I'm setting up CCNET server to run Selenium tests. In my test code I use the following to start the Selenium RC server if its not running:

var proc = new Process();
proc.StartInfo.WorkingDirectory = Path.Combine(Directory.GetParent(Assembly.GetExecutingAssembly().Location).FullName, @"..\..\..\..\..\lib\SeleniumRC\selenium-server-1.0-beta-2");
proc.StartInfo.FileName = "java"; //have also tried with "java.exe"
proc.StartInfo.Arguments = @"-jar selenium-server.jar -multiWindow -trustAllSSLCertificates -firefoxProfileTemplate ""..\Firefox Profiles\Relaxed Security""";
proc.StartInfo.UseShellExecute = true;
proc.Start();

This works great on my development machine. However, when I run it from CCNET.exe (under a user context), I can see that instead of executing the java.exe process, an explorer window pops up for "c:\windows\java". I think my path settings are messed up but I'm not sure how. Can you help?

Answer 1

Have you tried going to that working directory in a Command prompt under the user context you are running it under and trying the command line?

If the path settings are messed up, you can adjust them by right clicking the My computer, properties, Advanced, Environment Variables...

Answer 2

i use this one

public class Navegador : DefaultSelenium { private static int contadorPorta = 4444;

    private int porta;

    private delegate string OperacaoSelenium();

    // Variável para a URL Base
    private string urlBase;
    public string UrlBase
    {
        get { return urlBase; }
    }

    public Navegador(string urlBase)
        : base("localhost", contadorPorta, "*firefox", urlBase) // ou *firefox ou *chrome *safari, *opera , *iexplore etc.
    {
        this.urlBase = urlBase;

        porta = Navegador.contadorPorta;
        // Deve sempre abrir o Selenium RC-Server antes (instância única - Singleton)
        this.IniciarSeleniumRCServer();
        Navegador.contadorPorta++;

        this.Start();
        this.Open("/");
    }

    /// <summary>
    /// Inicia o Selenium RC-Server, que é o arquivo JAR que vem no pacote do Selenium RC
    /// </summary>
    private void IniciarSeleniumRCServer()
    {
        string seleniumParameters = "..\\..\\..\\ExternalLibraries\\selenium-remote-control-1.0-beta-1\\selenium-server-1.0-beta-1\\selenium-server.jar -Dhttp.proxyHost=10.100.100.24 -port " + porta + "";
        procSeleniumServer = System.Diagnostics.Process.Start("java.exe", " -jar " + seleniumParameters);
        System.Threading.Thread.Sleep(1000);
    }

works good.. but not under a proxy -.-'

Answer 3

I did this to start the server in the background:

// Start the java server
Process seleniumServer;
String javaFileLocation = @"C:\Program Files\Java\jre6\bin\java.exe";
String jarFileLocation = @"C:\SeleniumRC\selenium-remote-control-1.0.1\selenium-server-1.0.1\selenium-server.jar";
seleniumServer = new Process();
seleniumServer.StartInfo.FileName = javaFileLocation;
seleniumServer.StartInfo.Arguments = "-jar " + jarFileLocation;
seleniumServer.StartInfo.WorkingDirectory = jarFileLocation.Substring(0, jarFileLocation.LastIndexOf("\\"));
seleniumServer.StartInfo.UseShellExecute = true;
seleniumServer.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
seleniumServer.Start();

then just did

seleniumServer.Kill()

to stop it after all went well.

Not sure this will help the CCNET situation but may help people looking for this in future?

    {
        private static Process _seleniumServer;

            _seleniumServer = new Process
                                  {
                                      StartInfo =
                                          {

                                          }
                                  };
            _seleniumServer.Start();
        }

        public static void Stop()
        {
            _seleniumServer.Kill();
        }
    }

    [SetUp]
