c# - "Any"对象上的 MOQ stub 属性值

Question

我正在编写一些代码，这些代码遵循将方法的所有参数封装为“请求”对象并返回“响应”对象的模式。然而，这在使用 MOQ 进行模拟时产生了一些问题。例如:

public class Query : IQuery
{
    public QueryResponse Execute(QueryRequest request)
    {
        // get the customer...
        return new QueryResponse { Customer = customer };
    }
}

public class QueryRequest
{
    public string Key { get; set; }
}

public class QueryResponse
{
    public Customer Customer { get; set; }
}

...在我的测试中，我想 stub 查询以在给定 key 时返回客户

var customer = new Customer();
var key = "something";
var query = new Mock<ICustomerQuery>();

// I want to do something like this (but this does not work)
// i.e. I dont care what the request object that get passed is in but it must have the key value I want to give it

query.Setup(q => q.Execute(It.IsAny<QueryRequest>().Key = key))
     .Returns(new QueryResponse {Customer = customer});

我想要的最小起订量是否可行？

Answer 1

你在找什么It.Is<T>方法，您可以在其中为参数指定任何匹配器函数(Func<T, bool>)。

例如检查 key :

query.Setup(q => q.Execute(It.Is<QueryRequest>(q => q.Key == key)))
     .Returns(new QueryResponse {Customer = customer});
