here's the call inside a [Test]
_youTubeService.AssertWasCalled(d => d.GetFeedByAuthorWithRequest("Mark", Arg<YouTubeRequest>.Is.Anything));
here's the function on the interface for youtubeService:
Feed<Video> GetFeedByAuthorWithRequest(string author, YouTubeRequest request)
Here's the error Rhino Mocks gives me when I run the test:
System.InvalidOperationException : When using Arg, all arguments must be defined using Arg.Is, Arg.Text, Arg.List, Arg.Ref or Arg.Out. 2 arguments expected, 1 have been defined.
I use Arg.Is.Anything all the time with other types, usually strings, so I'm not sure what else it needs.
The exception message tells you what's wrong: all arguments must be defined using Arg....
You need to specify the argument "Mark" using Arg.Is
or Arg.Text
or some other static Arg
method.
