describe('stubbing library', function () {
 
    it('should stub resolving promise', function (done) {
 
        var original = {
            test: function () {

        var result;
 
        original.test().then(function (val) {
            result = val;
            expect(result).toEqual('value');
            expect(object.hasBeenResolved()).toBe(true);
            expect(object.hasBeenRejected()).toBe(false);

        expect(object.hasBeenRejected()).toBe(false);
        expect(result).not.toBeDefined();
 
        //flush pending promise
        object.flush();
    });
);

API

• when(service, methodName): create a stub and return it
• thenResolveWith(resolvedValue): tells the stub it should resolve with resolvedValue
• thenRejectWith(rejectValue): tells the stub it should reject the promise with rejectValue
• flush(): effectively resolve/reject the stub (note it is an asynchronous operation therefore you should put your assertion in the callback of the promise
• hasBeenResolved(): tells whether the stub has been resolved
• hasBeenRejected(): tells whether the stub has been rejected
