Multiple Browsers Tests using Webinator+Selenium, SpecFlow and NUnit

I'm developing an ASP.NET MVC 3 app with WebinatorSpecFlow+NUnit using the Selenium driver. I'm having a problem running parallel tests with Chrome (using chromedriver) and Internet Explorer.

Whenever I have both tests running in the same session and in parallel by Selenium via Webinator, IE seems to hang when I send any click action to the page.

I'm not able to use the solution suggested here, since SpecFlow generates the underlying C# code automatically. My solution is designed like this (the full code is available as a gist):

_multipleBrowsers.RunTest(web => web.GoToUrl("http://localhost/PROJECT/Authentication/Registration"));

What happens is that I instantiate a new IWebManager for every browser I need to test. Then, I call the delegate action, using the browser instance. It goes like this:

        foreach (var web in _webManagers)
        {
            Debug.WriteLine("Running test with " + web.Config.Browser);

            action(web);
        }

This way the tests run almost in parallel. It pops up a browser, execute the action, then the other browser, and so forth.

Any thoughts on how to overcome this ChromeDriver issue? Should I change my testing approach with SpecFlow for multiple browsers?

You can that much more simpler just use

Then you write feature with tag @Browser:IE

@Browser:IE
@Browser:Firefox
Scenario: Add comments
       Given I navigated to /guinea-pig
       And I have entered 'This is not a comment' into the commentbox
       When I press 'submit' 
       Then my comment 'This is not a comment' is displayed on the screen

For now is the best solution which i found since it also make sence to test not in all browsers but in specific which you need

I've created a new SpecFlow plugin that achieves the upvoted comment. It supports SpecFlow 3 (which means core too).

It also works with either MsTest, NUnit and xUnit.

The scenario and how it looks in test explorer can be seen here: img

But essentially you can do either:

@Browser:Chrome
@Browser:Firefox
Feature: AnExampleFeature

or

@Browser:Chrome
@Browser:Firefox
Scenario: AnExampleScenario

And the scenarios will run for each browser
