/**
* MockMoveService provides the same interface as the moveService,
* returning promises where it would normally do so. At it's core,
* it is a jasmine spy object, but it also tracks the promises it
* returns and provides shortcut methods for resolving those promises
* synchronously.
*
* Usage:
*
* ```javascript
* var moveService = new MockMoveService();
*
* // validate is a standard jasmine spy.
* moveService.validate.andReturn(true);
* var isValid = moveService.validate(object, parentCandidate);
* expect(isValid).toBe(true);
*
* // perform returns promises and tracks them.
* var whenCopied = jasmine.createSpy('whenCopied');
* moveService.perform(object, parentObject).then(whenCopied);
* expect(whenCopied).not.toHaveBeenCalled();
* moveService.perform.mostRecentCall.resolve('someArg');
* expect(whenCopied).toHaveBeenCalledWith('someArg');
* ```
