如何正确对DAL进行单元测试? [英] How to correctly unit test my DAL?

问题描述

我是单元测试的新手.但是，如何对用Entity Framework编写的DAL进行单元测试，以确保我的DAL代码可以正常工作，但实际上没有触及任何数据库?有人可以提供尽可能多的细节吗?

I'm new to unit testing. But how do I unit test my DAL which is written with Entity Framework, so I can make sure my DAL code is working correctly but no database is actually touched? Could someone give as much detail as possible please.

推荐答案

如果您要测试数据访问层是否正常工作，则确实需要在某个时候针对数据库进行测试，否则您实际上就不会对其进行测试有效.

If you want to test that your data access layer works correct you really need to test it against a database at some point as otherwise you aren't actually testing it works.
