We've managed to avoid dependency issues by creating an object that uses the Identity Map and Unit of Work patterns. The Identity Map keeps track of all the objects as we pull them from the database so we don't have to worry about duplicating objects. The Unit of Work functions as intermediary between the model and the functions used to retrieve and store data from our data sources. When we call the Unit of Work to do it's thing it goes through the list of objects in the Identity Map and performs any operations which need to be done on the objects. This allows us to create unit tests which test how our model functions and then separately test the methods they are taken from and stored to our data source. Of course, all of this is also completely separate from the controller ensuring we have a thin controller and a fat model.David KanenwisherOn Mon, Aug 23, 2010 at 8:59 AM, Hector Virgen <djvirgen@gmail.com> wrote:
It seems a lot of the solutions out there rely in static classes/methods/properties. How does this affect unit testing? And how do you encourage dependency injection with your fellow developers?
