Question

I’m using selenium-rc with C# to test my asp.net mvc2 application. Currently all I am doing is opening the home page with selenium RC.

when I run my test I see the selenium remote control open in a browser and I see my application open correctly in a browser but selenium shows a 404 error and aborts the test.

In an attempt to get this working I have cut the test down to a simple console app and have changed the default selenium port here is my code:

static void Main(string[] args)
    {
        try
        {
            var _selenium = new DefaultSelenium("localhost", 1234, "*chrome", "http://localhost:6666");
            _selenium.Start();
            _selenium.Open("/");

            try
            {
                _selenium.Stop();
            }
            catch (Exception)
            {
                // Ignore errors if unable to close the browser
            }

        }
        catch (Exception e)
        {
            Console.WriteLine(e);
        }
        Console.WriteLine("Done.");
        Console.ReadKey();

    }

this fails with the error “XHR ERROR: URL = /localhost:6666/ Response_Code = 404 Error_Message = Not Found on session 5f2e59798ae74e7cb741d50cae7e817a”

and if you look in the running selenium console you see

15:53:16.238 INFO - Allocated session 5f2e59798ae74e7cb741d50cae7e817a for http://localhost:6666, launching...

Interesting things that I have tried are:

change the site to “google” – then my test works
change the site to “google” port 80 then it doesnt work.
moved my site from cassini to iis 7 – didnt work
made my site the default site on iis 7 eg http://localhost/ – didnt work
I’ve used fiddler to watch the session – all requests fired return successfully.
I’ve tried passing -avoidProxy and -ensureCleanSession when starting the RC server. Hasn’t made any noticable difference.

If I reconfigure selenium to use the default port I get the following exception repeated over and over (once every 10 seconds / different sessionid each time). This doesn’t happen once I’ve changed the default port but i’ve included it just in case.

Can anybody shed some light?

Answer 1

I am using C# and had similar problem with selenium.open method. I have refered the thread haroonzone posted in his answer above. and have made following changes in my code

Declare selenium as

private DefaultSelenium selenium;

instead of

private ISelenium selenium;

and call open method as

    selenium.Processor.DoCommand("open", new String[] { YOUR_URL, "true" });

instead of

    selenium.Open("YOUR_URL");

Additionally, you may want to call

selenium.SetTimeout("600000");

before DoCommand
