推荐答案

我建议使用以下格式.这有助于通过查看测试方法名称来了解您究竟在测试什么.

I would suggest to use following format. This helps to know what exactly you are testing by just looking at the test method name.

[UnitOfWork_StateUnderTest_ExpectedBehavior]

GetCustomerById_WithValidId_ReturnsCustomer
GetCustomerById_WithInvalidId_ReturnsNull
