c# - 使用Rhino Mocks如何检查传递给模拟对象的参数中结构字段的值？

Question

在Rhino Mocks中，我正在测试Subject类中名为Store的方法。subject.Store(Member) 内部调用 IStore.Store(Person)。如何检查在 Member 上设置的名称参数是否与调用 IStore.Store(Person) 时的 Person 参数中存在的名称相同。

显然，在结构中实现 Equals 方法然后调用 Arg.Is.Equals 是一种选择。但我无法控制 Person 或 Member 结构的源代码。

这是代码片段..

struct Person {
        string name;
        int age;
        char sex;
    }

    struct Member {
        string name;
        string address;
        string departnemt;

        public Member(string name, string address, string departnemt) {
            // TODO: Complete member initialization
            this.name = name;
            this.address = address;
            this.departnemt = departnemt;
        }
        //other methods
    }

    interface IStore {
        void Store(Person p);
        //other methods
    }

    class Subject {
        IStore db;
        public void Store(Member m) {
            //some logic to convert Member to Person
            Person p = GetPersonFromMember(m);
            db.Store(p);
        }

        //other methods
    }

[Test]
        public void TestStore() {
            //Arrange
            Member m = new Member("dave", "crawford Ave", "Physics");

            var mockStore = MockRepository.GenerateMock<IStore>();
            mockStore.Expect(x => x.Store(Arg<Person>.Is.NotNull));
            //here i also want to check that the Person.Name is "dave"
            //how can i do this?

            //Act
            subject.Commit();

            //Assert
            mockStore.VerifyAllExpectation();
        }

代替 Arg<Person>.Is.NotNull 或除了这样做之外你可以做Arg<Person>.Property.Value("Name", m.Name)

另外假设您正在使用 .Net 3.5 或更高版本，您可以执行一些您可能认为或可能不认为读起来更好的操作，并避免使用带有属性名称的字符串: Arg<Person>.Matches(p => p != null && p.Name == m.Name)
