我通常会完全按照您最终在测试中所做的来做.在编写测试时，我假设.Net库类可以正常工作，并且不包含错误，因此可以在测试中使用它们.当我需要测试列表，集合，可查询的字典等时，我只需创建真实的东西并填充测试数据即可.它使测试的可读性和编写速度更快，并且老实说，这种风险不存在.

I usually do exactly what you ended up doing in your test. When writing my tests I assume that the .Net library classes work correctly and don't contain bugs, so I can use them in the tests. When I need a test list, collection, queryable, dictionary, etc. I just create the real thing and populate with test data. It makes the tests much more readable and quicker to write, and to be honest the risk is non-existent.
