It is sometimes handy to just mock the call to server.MapPath. This solution works for me using moq. I only mock the base path to the application.

        _contextMock = new Mock();
        _contextMock.Setup(x => x.Server.MapPath("~")).Returns(@"c:\yourPath\App");
        _controller = new YourController();
        _controller.ControllerContext = new ControllerContext(_contextMock.Object, new RouteData(), _controller);

In your controller you can now user Server.MapPath("~").
