OperaDriver not working

Using Selenium Grid2 and RemoteWebDriver in an MSTest class, I am struggling to get OperaDriver working.

I create the Selenium hub and Opera node by running the following commands in CMD:

start java -jar selenium-server-standalone-2.30.0.jar -role hub
start java -jar selenium-server-standalone-2.30.0.jar -role node -port 7001 -browser "browserName=opera,version=11.62,maxInstances=5,platform=WINDOWS" -hub http://localhost:4444/grid/register

And this works fine, I can the see the registered node when I view my hub in a browser.

But I get an exception whenever I try to create a new WebDriver in my C# test class:

DesiredCapabilities operaCapabilities = DesiredCapabilities.Opera();
operaCapabilities.SetCapability(CapabilityType.BrowserName, "opera");
operaCapabilities.SetCapability(CapabilityType.Platform, "WINDOWS");
operaCapabilities.SetCapability(CapabilityType.Version, "11.62");
operaCapabilities.SetCapability("opera.binary", "C:\\Program Files\\Opera\\opera.exe");
operaCapabilities.SetCapability("opera.port", 7001);
RemoteWebDriver operaDriver = new RemoteWebDriver(operaCapabilities);

Actually I get two different exceptions - the first time after creating the hub and node in Selenium I get this:

Could not find a platform that supports bundled launchers, please set it manually

Build info: version: '2.30.0', revision: 'dc1ef9c', time: '2013-02-19 00:15:27'

System info: os.name: 'Windows 8', os.arch: 'x86', os.version: '6.2', java.version: '1.7.0_15'

Driver info: driver.version: OperaDriver

And everytime after that I get the following error:

Could not initialize class com.opera.core.systems.runner.launcher.OperaLauncherRunner

I am using Selenium-standalone-2.30.0.

I was using Opera version 12.14 but downgraded to 11.62 after I saw a list of compatible versions on the OperaDriver wiki page but the errors remain the same.

I have tried initialising the RemoteWebDriver with and without the capabilities above and get the same result every time.

Does anyone know what the problem is here and how to get a RemoteWebDriver working with Opera in this way?

Edit: Could it be that the platform for Opera version 12.14 reads as 'WINDOWS 8', and version 11.62 reads as "WIN32" when I open the Opera browser and view Help => About? As I am specifying the platform as WINDOWS in the node and RemoteWebDriver. If I try to specify WINDOWS 8 as the platform for the RemoteWebDriver an new exception is thrown where it can't find matching enum:

org.openqa.selenium.WebDriverException: java.lang.IllegalArgumentException: No enum constant org.openqa.selenium.Platform.WINDOWS 8

Edit2: For some reason CurrentPlatform is returning Vista for me, even though I am running Windows8.

Platform platform = Platform.CurrentPlatform;

And I also noticed that the OperaDriver source code checks for 'VISTA' in uppercase whereas the Platform in C# reads as 'Vista'.

Could this be causing the problem?

I've been suffering from this problem as well and thanks to the hint from eviltester I was able to solve the issue by using the following command line to start the selenium server:

java -Dos.name=windows -jar selenium-server-standalone-2.32.0.jar

The use of -Dos.name=windows is the equivalent of System.setProperty("os.name", "windows") and will allow your C# selenium code to work for the Opera browser.

I saw this when running in Java. In debug mode it looked like a possible omission in OperaLauncherRunner.java launcherNameForOS does not cater for the WIN8 enum returned by Platform.getCurrent().

In Java I fudged it by setting the system property "os.name" to "windows" before creating a new OperaDriver. This forced the Platform.getCurrent to return XP which the opera launcher was happy with.

So in java I just used this hack:

System.setProperty("os.name","windows");
driver = new OperaDriver();
