Problem with async Jasmine tests.

auth.js

define([
    'service/auth'
    ], function(
        auth
    ) {

    describe('Tests "auth" service', function() {

        var data;

        var OPTIONS = {
                CN: '147144147',
                GV: '147153162'
            };

        auth.on.success.addOnce(function( response ) {
            data = response;
        });

        auth.request(OPTIONS);

        it('"status" should exist and be "true"', function() {

            waitsFor(function() {
                return data !== undefined;
            });

            runs(function() {
                expect(data['status']).toBeDefined();
                expect(data['status']).toBeTruthy();
            });

        });

    });
});

login.js

define([
    'service/login'
    ], function(
        login
    ) {

    describe('Tests "login" service', function() {

        var data;

        var OPTIONS = {
                oper: 1,
                codigoouemail: '101',
                senha: '10151015'
            };

        login.on.success.addOnce(function( response ) {
            data = response;
        });

        login.request(OPTIONS);

        it('Should get the service response for user "' + OPTIONS.codigoouemail + '"', function() {

            waitsFor(function() {
                return data !== undefined;
            });

            runs(function() {
                expect(data).toBeDefined();
            });

        });

    });
});
