[c#] Returning value that was passed into a method
Even more useful, if you have multiple parameters you can access any/all of them with:
_mock.Setup(x => x.DoSomething(It.IsAny<string>(),It.IsAny<string>(),It.IsAny<string>()) .Returns((string a, string b, string c) => string.Concat(a,b,c));
You always need to reference all the arguments, to match the method's signature, even if you're only going to use one of them.
I have a method on an interface:
string DoSomething(string whatever);
I want to mock this with MOQ, so that it returns whatever was passed in - something like:
_mock.Setup( theObject => theObject.DoSomething( It.IsAny<string>( ) ) ) .Returns( [the parameter that was passed] ) ;
