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