unit-testing - 如何对在密封的非泛型类中调用泛型方法的非泛型方法进行单元测试？

Question

使用[assembly:InternalsVisibleTo()]和

public sealed class AppService
{
    //TODO: fix dev's spelling
    //want to test this
    public AddSubscribtionResponse AddSubscribtion(AddSubscribtionRequest request)
    {
        return ExecuteQueryProc<AddSubscribtionResponse>("spAddAppToUserGroup", request).First();
    }

    //I want to stub or interaction test the call to here
    #if DEBUG
    internal
    #endif
    List<T> ExecuteQueryProc<T>(string query, object parameters = null)
    {
        var cn=GetConnection();
        //DatabaseCommand is a static class =(
        return DatabaseCommand.ExecuteQueryProc<T>(cn, query, parameters);
    }
}

我在让 Rhino 存根或拦截 Execute Query proc 方法方面所做的每一次尝试都失败了。

var service = MockRepository.GeneratePartialMock<AppService>(null);
service.Stub(f => f.ExecuteQueryProc<AddSubscribtionRequest>(null, null)).IgnoreArguments().Return(new List<AddSubscribtionRequest>());

var expected = new AddSubscribtionRequest();
var actual = service.AddSubscribtion(expected);

投掷 System.InvalidOperationException: ExecuteReader: CommandText property has not been initialized

从你的类中删除“密封”（如果它不能从它继承，Rhino.Mocks 就不能代理你的类）。并且 ExecuteQueryProc 必须是虚拟的才能存根其功能。
