Sharepoint unit testing using fakes framework

Question

I have an application which uploads a file to SharePoint via client object model. Now I need to write unit test cases for this application. The problem is, I how do I write test cases for the scenarios when

1. a folder exists
2. a folder does not exist

since this scenario can change anytime i cannot hardcore a folder name. I need to use Microsoft fakes framework. But can I use shims? If so... how to use it?

Thanks for the help!

According to article Using emulators to isolate unit tests for Sharepoint 2010 applications, Microsoft SharePoint Emulators provide a set of shims including SPFolder object, so the following test case could be used:

[TestMethod]
private bool CheckFolderExists(sting url,string folderName) 
{
    using (new SharePointEmulationScope(EmulationMode.Enabled))      
    {      
        SPSite site = new SPSite(url);

        //act    
        SPFolder folder = site.RootWeb.GetFolder(folderName);
        var success = folder.Exists;

        // assert 
        Assert.IsTrue(success);

        // cleanup  
        site.Dispose(); 
}
