Multiple return values for When/Do

[Łukasz Łysik]

I need to use when/do feature which is different over different calls.

In the documentation there is an example, and the description which says, that the "Do" corresponds to "Returns" method for non-void methods. So I'd expect that it would be possible to use it this way: 

var foo = Substitute.For<IFoo>();

    foo.When(x => x.SayHello("World"))

        .Do(x => { throw new Exception;}, x => {return counter++; });

However, "Do" function doesn't accept multiple parameters. Do you plan to implement this feature? How can I achieve this functionality in a neat way?

Thanks,

Lukasz

Hi Lukasz,

I hadn't thought of that before. The feature isn't planned, but you can use a Queue<Action<CallInfo>> to get the behaviour you want. 

Here is an example: https://gist.github.com/dtchepak/8567647

David
