Unit Testing Entity Framework with Effort

Previous posts in this series Rich Domain Models and Entity Framework. A CQRS Implementation with ASP.Net MVC and Entity Framework . Introduction to the series . Introduction In my previous post I discussed steps I've been taking with recent application to move more logic and behaviour into a richer domain model. This has a number of advantages, a significant one being ease of testing of this behaviour. As this is coded as methods on a standalone model class, it's very easy to test due to it's lack of dependencies. Nothing needs to be mocked or stubbed; an instance can just be instantiated in the test method and the appropriate methods called and results asserted. Given the CQRS style approach I've taken elsewhere in the applications, MVC controllers are fairly light and have less value for testing. The main part of the application where logic lies is in the individual query and command handlers. These have a tight dependency on Entity Framework thoug

Rich Domain Models and Entity Framework

Previous posts in this series A CQRS Implementation with ASP.Net MVC and Entity Framework . Introduction to the series . Working with a Rich Domain Model and Entity Framework As described in previous posts in this series, I'm documenting a few changes to the way I've recently been building out ASP.Net MVC applications, following various influencers from blogs and books. One area I was keen to look at was creating a rich domain model - inspired by the Eric Evans classic book and some posts by Julie Lerman and Jimmy Bogard. Previously I would have worked more with what is known as an anaemic domain model - which isn't quite as bad as it sounds... but means that when creating entities for use in Entity Framework Code First, they would in the most part be made of a simple set of properties with public getters and setters. With a rich domain model, we look to push more behaviour into these model classes and provide tighter means of control over their use by callin
