EF4-可以模拟ObjectContext进行单元测试吗? [英] EF4 - possible to mock ObjectContext for unit testing?

问题描述

可以不使用TypeMock Islolator来完成吗?我在网上发现了一些建议，例如传递仅元数据的连接字符串，但是除了TypeMock之外，我所遇到的其他事情似乎都没有真正允许将模拟ObjectContext注入到用于单元测试的服务中.我是否会为TypeMock降低$$费用，还是有其他选择?没有人能创建与开源的TypeMock相当的东西吗?

Can it be done without using TypeMock Islolator? I've found a few suggestions online such as passing in a metadata only connection string, however nothing I've come across besides TypeMock seems to truly allow for a mock ObjectContext that can be injected into services for unit testing. Do I plunk down the $$ for TypeMock, or are there alternatives? Has nobody managed to create anything comparable to TypeMock that is open source?

推荐答案

我正在轻松地对EF4进行单元测试，而无需进行模拟.我所做的就是使用来自

I'm unit testing EF4 easily without mocking. What I did was create a repository interface using the code from http://elegantcode.com/2009/12/15/entity-framework-ef4-generic-repository-and-unit-of-work-prototype/ as a basis I then created an InMemoryRepository<T> class that used the IRepository interface. I then replaced the IObjectSet<T> with a List<T> inside of the class and changed the retrieval methods accordingly.

因此，如果需要进行单元测试，请传入InMemoryRepository而不是DataRepository.

Thus if you need to do unit testing, pass in the InMemoryRepository rather than the DataRepository.
