TDD：EF Core In Memory Provider 是否验证引用约束？
TDD: Does EF Core In Memory Provider validates referential constraints?
我对 EF Core 用于单元测试的内存功能感到非常兴奋。它减轻了我编写专用存储库的负担，只是为了使代码可单元测试。但仅在集合中进行内存测试是不够的。
Does EF Core In Memory Provider validates referential constraints?
Does EF Core In Memory Provider validates referential constraints?
答案是：没有
InMemory 提供程序不能替代关系数据库。它是为测试目的而创建的。
摘自documenation：
InMemory is designed to be a general purpose database for testing, and
is not designed to mimic a relational database.
Some examples of this include:
InMemory will allow you to save data that would violate referential
integrity constraints in a relational database.
If you use DefaultValueSql(string) for a property in your model, this
is a relational database API and will have no effect when running
against InMemory.
第一点是提供者未验证任何约束。
