How to Work With Generic Repositories on ASP.NET MVC and Unit Testing Them By Mocking In this blog post we will see how to work with generic repositories on ASP.NET MVC and unit testing them by mocking with moq @  12-22-2011 by Tugberk Ugurlu ASP.NET MVC   C#   DbContext   Entity Framework   Unit Testing I have blogged about  Generic Repository Pattern - Entity Framework, ASP.NET MVC and Unit Testing Triangle  but that blog post only contains how we can implement that pattern on our DAL (Data Access Layer) project. Now, let’s see how it fits into our  ASP.NET MVC  application. I created a sample project which basically has CRUD operations for  Foo  class and I put the complete code of the project on  GitHub .  https://github.com/tugberkugurlu/GenericRepoWebApp So, in the previous blog post we have created our DAL project and repository classes based on our generic repository. I have ...
