如何使用 NUnit.Mocks 模拟通用存储库？

我正在开发通用存储库我想使用 NUnit.Mocks 来测试它。根据 Mike Hadlow 在他的文章中的说法，你可以使用像这样的 Rhino 模拟来做到这一点：

User[] users = new User[] { };
...
Expect.Call(userRepository.GetAll()).Return(users);

所以我想也许我可以在 NUnit.Mocks 中写同样的东西，如下所示：

dataProviderMock = new DynamicMock(typeof(IDataProvider<User>));
var user = new User {Username = "username", Password = "password"};
var users =new[]{ user };
dataProviderMock.ExpectAndReturn("GetAll",users);

但我得到了一个 InvalidCastException 正如我所期望的，因为没有办法进行强制转换IQueryable 的用户数组。所以问题是如何使用 NUnit.Mocks 模拟 IQueryable？

I'm working on a generic repository and I would like to test it using a NUnit.Mocks . According to Mike Hadlow in his article you can do it using Rhino mocks like this:

User[] users = new User[] { };
...
Expect.Call(userRepository.GetAll()).Return(users);

So I thought maybe I could write the same thing in NUnit.Mocks like this :

dataProviderMock = new DynamicMock(typeof(IDataProvider<User>));
var user = new User {Username = "username", Password = "password"};
var users =new[]{ user };
dataProviderMock.ExpectAndReturn("GetAll",users);

but I'm getting an InvalidCastException as I expected since there's no way to cast an array of users to an IQueryable.
So here's the question how can I mock an IQueryable using NUnit.Mocks?

这比我想象的要容易:)
有一个 AsQueryable() 扩展方法，可以将数组转换为 IQueryable。
因此，使用 Rhino Mocks 还是 NUnit.Mocks 并不重要。
这就是我所做的：

dataProviderMock = new DynamicMock(typeof(IDataProvider<User>));
var user = new User {Username = "username", Password = "password"};
var users =new[]{ user };
dataProviderMock.ExpectAndReturn("GetAll",users.AsQueryable());

It was easier than I thought :)
There is this AsQueryable() extension method that lets convert an array to an IQueryable.
So it doesn't matter if you are using Rhino Mocks or NUnit.Mocks.
Here's what i did :

dataProviderMock = new DynamicMock(typeof(IDataProvider<User>));
var user = new User {Username = "username", Password = "password"};
var users =new[]{ user };
dataProviderMock.ExpectAndReturn("GetAll",users.AsQueryable());
