The URL Specified () does not correspond to a valid directory.

When trying to run a unit test I get this error:

Test Name: GetMethodTest Test FullName: Quanser.Codex.App.Web.Repository.UnitTests.DocumentsControllerTests.GetMethodTest Test Source: c:\Dev\Engineering\Mobile Apps\Software\Codex\trunk\Web\Repository\UnitTests.Repository\DocumentsControllerTests.cs : line 34 Test Outcome: Failed Test Duration: 0:00:00

Result Message: The URL specified ('http://localhost:53364/') does not correspond to a valid directory. Tests configured to run in ASP.NET in IIS require a valid directory to exist for the URL. The URL may be invalid or may not point to a valid Web application.

This is my test case:

    [TestMethod()]
    [HostType("ASP.NET")]
    [UrlToTest("http://localhost:53364/")]
    public void GetMethodTest() 
    {
      // ...
    }

I know there is something wrong with this line:

 [UrlToTest("http://localhost:53364/")]

What should I put as the Url in this attribute?

Note: I need to use these attributes for testing the REST API

Thanks
