How to catch/deal with System.InvalidOperationException(UnexpectedJavaScriptError)

[Abs]

Hi,

I have created a sample class file in C# to explore
WebDriverBackedSelenium (as shown below).

The question that I have is, when I try to fire an invalid method on
an element like in the example below where I try to fire Type on the
Google logo ‘hplogo’, instead of getting an exception which should be
caught in the try-catch block I get an error
‘System.InvalidOperationException was unhandled, Message="JavaScript
error (UnexpectedJavaScriptError)"’ which is not handled by the try
catch block. Is there some workaround to this issue where in I can get
a proper message in the try-catch block instead of the run being
halted?


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using OpenQA.Selenium;
using OpenQA.Selenium.IE;
using OpenQA.Selenium.Firefox;
using Selenium;

namespace WindowsFormsApplication1
{
class Class1
{

IWebDriver driver;
ISelenium selenium;

public void Setup()
{
try
{
driver = new InternetExplorerDriver();
selenium = new WebDriverBackedSelenium(driver, "http://
www.google.co.in");
selenium.Start();

}
catch (Exception e)
{
Console.WriteLine("Setup", e);
}
}

public void Teardown()
{
driver.Quit();
}

public void TestSearchGoogle()
{
try
{

selenium.Open("http://www.google.co.in");
selenium.Type("hplogo", "test");

}
catch (Exception e)
{
Console.WriteLine("{0} Exception caught.", e);
}


}

}
}
