C#。如何测试我试图测试的同一类中的方法

我班上有方法 CustomerServices 我需要模拟和测试。我不确定我的嘲笑是否正确?当代码命中时进行调试 customerService.Object.ProcessCustomer() 则它不调用实际的方法。

如果方法是从其他类调用的,我知道如何在contractor中使用DI和引用对象进行模拟,但我不知道如何模拟我试图测试的同一类中存在的方法??

我正在使用mock和autoFixture

顾客

public class Customer
{
    public string Name { get; set; }
    public string Address { get; set; }
}

界面

public interface ICustomerServices
{
    List<Customer> GetCustomers();
    int ProcessCustomer();
}

客户服务

public class CustomerServices : ICustomerServices
{
    public CustomerServices()
    {

    }

    public int ProcessCustomer()
    {
        var customerList = GetCustomers();

        Console.WriteLine($"Total Customer Count {customerList.Count()}");

        return customerList.Count();
    }

    public List<Customer> GetCustomers()
    {
        return new List<Customer>();
    }
}

Test

public class Tests
{
    private readonly Mock<ICustomerServices> customerService;

    public Tests()
    {
        customerService = new Mock<ICustomerServices>();
    }

    [SetUp]
    public void Setup()
    {
    }

    [Test]
    public void Test1()
    {
        //Arrange 
        var fixture = new Fixture();

        var customerMoq = fixture.CreateMany<Customer>(5);
        customerService.Setup(_ => _.GetCustomers()).Returns((System.Collections.Generic.List<Customer>)customerMoq);

        //Act
        var actualResult = customerService.Object.ProcessCustomer();

        //Assert
    }
}

您不应该嘲笑正在测试的服务。

你的测试应该更像这样:

[TestMethod]
public void TestGetUser()
{
    var mockLogger = new Mock<ILogger>(MockBehaviour.Strict);
    var mockSomeOtherDependency = new Mock<IA>(MockBehaviour.Strict);

    var beingTested = new UsersService(
        logger: mockLogger.Object
        someOtherDependency: mockSomeOtherDependency.Object,
        ...);

    mockSomeOtherDependency.Setup( r => r.GetCustomer("test")).Returns( new Customer(...));

    var r = beingTested.ProcessCustomer(); 

    Assert.IsNotNull(r);
}
