Question

I’m testing a website with Specflow and WebDriver.
I’m using events of specflow to start and quit the Driver. I start the Driver in [BeforeFeature] and quit it in [AfterFeature].

I use a static Common Class to hold the Driver and have the methods to operate it.

The problem happens after all tests are run on a feature and the next feature starts to run. I get the following errors.:

If in the [AfterFeature] I do a Driver.Close() I get the error:

    -> error: Unexpected error. System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:7055

If I do a Driver.Quit() I get the error:

-> error: Cannot deserialize JSON object into type 'System.String'. Line 1, position 35.

If I don’t close or quit the driver, Every Features run with no problem, but I get lots of opened Firefox Windows.

My code is:

[Binding]
public class Events
{
    [BeforeFeature]
    public static void BeforeFeature()
    {
        Common.CreateDriver();
    }

    [AfterFeature]
    public static void AfterFeature()
    {
        Common.QuitDriver();
    }
}

And…

public static class Common
{
    public static IWebDriver Driver { get; set; }        

    public static void CreateDriver(){            
        Driver = new FirefoxDriver();
        Driver.Manage().Timeouts().ImplicitlyWait(new TimeSpan(0, 0, 5));        
    }

    public static void CloseDriver()
    {
        Driver.Close();
    }

    public static void QuitDriver()
    {
        Driver.Quit();
    }
}

Just found out what the problem was.
I will put it here for future reference.

The problem was in the way I was reading the Driver on my BaseWebObject, the father of all PageObjects.

I had this:

    public class BaseWebObject
{        
    protected static IWebDriver Driver = Common.Driver;

}   

This Fails because the Driver will only be read once in the static constructor.

To make it work I must read the Driver at the instantiation time, so in the instance constructor like so:

    public class BaseWebObject
{        
    protected static IWebDriver Driver;

    public BaseWebObject()
    {
        Driver = Common.Driver;
    }    
}
