Testing per request view cache implementation

bootstrapper.cs

In ConfigureRequestContainer:

#ifdef DEBUG
context.Items["DebugViewCache"] = existingContainer.Resolve<IViewCache>();
#endif

TestRenderContextFactory.cs

public class TestRenderContextFactory : IRenderContextFactory
{
    private IViewResolver viewResolver;
    private IViewCache viewCache;
    
    public TestRenderContextFactory(IViewResolver viewResolver, IViewCache viewCache)
    {
        this.viewResolver = viewResolver;
        this.viewCache = viewCache;
    }
    
    public IRenderContext GetRenderContext(ViewLocationContext viewLocationContext)
    {
        return new DefaultRenderContext(
                        this.viewResolver,
                        viewLocationContext.Context.Items.ContainsKey("DebugViewCache") ? 
                            viewLocationContext.Context.Items["DebugViewCache"] as IViewCache :
