AngularJS Essentials

Services
For now, let's create a service based on our parkingFactoryFunction function,
as follows:
parkingApp.js
var parking = angular.module("parking", []);
parkingService.js
parking.factory("parkingService", function () {
var _calculateTicket = function (car) {
var departHour = car.depart.getHours();
var entranceHour = car.entrance.getHours();
var parkingPeriod = departHour - entranceHour;
var parkingPrice = parkingPeriod * 10;
return {
period: parkingPeriod,
price: parkingPrice
};
};
return {
calculateTicket: _calculateTicket
};
});
Chapter 7
To avoid duplicated setup and teardown code, Jasmine provides two important
functions, beforeEach and afterEach, which are executed before and after the
execution of each test. With the module function of ngMock, we can load the desired
module and inject its components through the inject function just by informing
the name of the component. Optionally, we may enclose the name of the component
with underscores. In the following code, we are loading the parking module and
injecting the parkingService specification:
parkingServiceSpec.js
describe("Parking Service Specification", function () {
var parkingService;
beforeEach(module("parking"));
beforeEach(inject(function (_parkingService_) {
