sinon - create stub that returns own arguments

How can I make a stub that returns it's own arguments, like so:

var stub = sinon.stub().returns(???);

var result = stub('foo'); //result = foo

This will be nested so I can't return nothing and then check stub.getCall...

Modify your code like below:

- var stub = sinon.stub().returns(???);
+ var stub = sinon.stub().returnsArg(0);

var result = stub('foo'); //result = foo
