Setup multiple expectations on a method in Rhino.Mocks
What's the correct way to setup multiple expectations on a method if you need a different return value for each consecutive invocation in Rhino.Mocks V3.6?
The following code used to work in V3.5 but fails in V3.6.
public void Test()
{
var mocks = new MockRepository();
var process = mocks.DynamicMock<IProcess>();
Expect.Call(process.Run()).Return(1);
E开发者_JS百科xpect.Call(process.Run()).Return(2);
mocks.ReplayAll();
Assert.That(process.Run(), Is.EqualTo(1));
Assert.That(process.Run(), Is.EqualTo(2));
mocks.VerifyAll();
}
public interface IProcess
{
int Run();
}
I'm not sure if this is the correct way - but it works :)
var queue = new Queue<int>(new [] {1, 2, 3});
var mockObject = MockRepository.GenerateMock<IdGenerator>();
mockObject.Expect(calc => calc.GetNext())
.Do( (Func<int>) queue.Dequeue);
Console.Out.WriteLine(mockObject.GetNext()); // returns 1
Console.Out.WriteLine(mockObject.GetNext()); // returns 2
Console.Out.WriteLine(mockObject.GetNext()); // returns 3
The last time I needed this I created an extension method (although for Moq). Worked out pretty well for me..
_mockClock.Setup(clock => clock.GetCurrentTime())
.ReturnsNextValueFrom(transitionTimestamps);
