|
* MockLinkService provides the same interface as the linkService,
|
|
* 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 linkService = new MockLinkService();
|
|
*
|
|
* // validate is a standard jasmine spy.
|
|
* linkService.validate.andReturn(true);
|
|
* var isValid = linkService.validate(object, parentObject);
|
|
* expect(isValid).toBe(true);
|
|
*
|
|
* // perform returns promises and tracks them.
|
|
* var whenLinked = jasmine.createSpy('whenLinked');
|
|
* linkService.perform(object, parentObject).then(whenLinked);
|
|
* expect(whenLinked).not.toHaveBeenCalled();
|
|
* linkService.perform.mostRecentCall.promise.resolve('someArg');
|
|
* expect(whenLinked).toHaveBeenCalledWith('someArg');
|
|
* ```
