Desired capabilities ignored

[Ryan]

Hi,

I'm just getting started with Selenium Grid. I've used the following
commands to start up the hub and 1 remote control session:

> java -jar selenium-server-standalone-2.7.0.jar -role hub -port 80

> java -jar selenium-server-standalone-2.7.0.jar -role webdriver -hub http://localhost:80/grid/register -port 5555 -browser "browserName=internet explorer,version=8,platform=WINDOWS"

(I've also tried not specifying the -browser parameter and just
specifying -browserName="internet explorer")

..and the grid console shows that there is one IE node registered.

My test starts like this:
var hubUrl = Settings1.Default.hubUrl;

var dc = DesiredCapabilities.InternetExplorer();
driver = new RemoteWebDriver(new Uri(hubUrl), dc);

but I can never get the remote control to use IE. When Firefox was
installed it always used that - after I've now uninstalled it, I
receive the following exception:

SeleniumPlay.SeleniumTests (TestFixtureSetUp):
SetUp : System.InvalidOperationException : Cannot find firefox binary
in PATH. Make sure firefox is installed. OS appears to be: XP

os.version: '6.0', java.version: '1.7.0'

The logs from the hub are:

What am I doing wrong?!

Thanks,

Hello,

it doesn't seem grid related.
Can you try using the same setup but target the node directly to confirm it :
 var dc = DesiredCapabilities.

InternetExplorer();
           driver = new RemoteWebDriver(new Uri("http://localhost:5555/wd/hub"), dc);

I think it will produce the same error indicating that webdriver cannot find IE.

thanks,
françois

Hi François,

Thanks for the reply. Yes - it's exactly the same exception, so this
doesn't appear to be hub related.

I would also try to output what the capability settings are.
The .toString() method does this for you. It helped me find a problem
in how I configured the capabilities for IE versus the other
browsers. Since it seems to be trying to bring up Firefox I have a
feeling the capabilities setting doesn't match what you have
configured, so to is trying to do a default browser, which in this
case is Firefox.
