Question

我正在尝试首次为单元测试设置Moq。我已经针对真实数据库测试了工作单元和存储库，我可以插入，删除，按ID查找等等（我正在使用TPH，因为我有住宅客户以及商业客户。）此测试与Moq有效：

const int expectedId = 1;
ResidentialCustomer expected = new ResidentialCustomer("Bob", "Smith")
{
    Id = expectedId,
    AccountNumber = 1
};

IQueryable<ResidentialCustomer> data = new List<ResidentialCustomer>
{
    expected,
    new ResidentialCustomer("Nancy", "Smith") {Id = 2, AccountNumber = 2},
    new ResidentialCustomer("John", "Doe") {Id = 3, AccountNumber = 3},
    new ResidentialCustomer("Jane", "Doe") {Id = 4, AccountNumber = 4}
}.AsQueryable();

var dbSetMock = new Mock<IDbSet<Customer>>();
dbSetMock.Setup(m => m.Provider).Returns(data.Provider);
dbSetMock.Setup(m => m.Expression).Returns(data.Expression);
dbSetMock.Setup(m => m.ElementType).Returns(data.ElementType);
dbSetMock.Setup(m => m.GetEnumerator()).Returns(data.GetEnumerator());

var customDbContextMock = new Mock<RealContext>();
customDbContextMock
    .Setup(x => x.Customers)
    .Returns(dbSetMock.Object);

var actual = (ResidentialCustomer) customDbContextMock.Object.Customers.First();

Assert.IsNotNull(actual);
Assert.AreEqual(expected.Id, actual.Id);
Assert.AreEqual(expected.FirstName, actual.FirstName);

此测试不（更新）：＆＃39;实际＆＃39;为null，第一个Assert失败。

const int expectedId = 1;
ResidentialCustomer expected = new ResidentialCustomer("Bob", "Smith")
{
    Id = expectedId,
    AccountNumber = 1
};

IQueryable<ResidentialCustomer> data = new List<ResidentialCustomer>
{
    expected,
    new ResidentialCustomer("Nancy", "Smith") {Id = 2, AccountNumber = 2},
    new ResidentialCustomer("John", "Doe") {Id = 3, AccountNumber = 3},
    new ResidentialCustomer("Jane", "Doe") {Id = 4, AccountNumber = 4}
}.AsQueryable();

var dbSetMock = new Mock<IDbSet<Customer>>();
dbSetMock.Setup(m => m.Provider).Returns(data.Provider);
dbSetMock.Setup(m => m.Expression).Returns(data.Expression);
dbSetMock.Setup(m => m.ElementType).Returns(data.ElementType);
dbSetMock.Setup(m => m.GetEnumerator()).Returns(data.GetEnumerator());

var customDbContextMock = new Mock<RealContext>();
customDbContextMock
    .Setup(x => x.Customers)
    .Returns(dbSetMock.Object);

var uow = new UnitOfWork(customDbContextMock.Object);
var repo = uow.CustomerRepository;

var actual = (ResidentialCustomer) repo.GetAllCustomers().First();

Assert.IsNotNull(actual);
Assert.AreEqual(expected.Id, actual.Id);
Assert.AreEqual(expected.FirstName, actual.FirstName);

提前谢谢你......
