 *
 * The `angular.mock` object is a namespace for all built-in mock services that ship with angular.
 * It automatically replaces real services if the `angular-mocks.js` file is loaded after
 * `angular.js` and before any tests.
 *
 * Built-in mocks:
 *
 * * {@link angular.mock.service.$browser $browser } - A mock implementation of the browser.
 * * {@link angular.mock.service.$exceptionHandler $exceptionHandler } - A mock implementation of
 *   the angular service exception handler.
 * * {@link angular.mock.service.$log $log } - A mock implementation of the angular service log.

 * This service is a mock implementation of {@link angular.service.$browser}. It provides fake
 * implementation for commonly used browser apis that are hard to test, e.g. setTimeout, xhr,
 * cookies.
 *
 * This implementation is automatically available and replaces regular `$browser` service in tests
 * when `angular-mocks.js` is loaded.
 *
 * The api of this service is the same as the real {@link angular.service.$browser $browser}, except
 * that there are several helper methods available which can be used in tests.
 *
 * The following apis can be used in tests:
 *
 * - {@link angular.mock.service.$browser.xhr $browser.xhr} — enables testing of code that uses
 *   the {@link angular.service.$xhr $xhr service} to make XmlHttpRequests.
 * - $browser.defer — enables testing of code that uses
 *   {@link angular.service.$defer $defer service} for executing functions via the `setTimeout` api.

 * !!!! WARNING !!!!!
 * This is not a complete Date object so only methods that were implemented can be called safely.
 * To make matters worse, TzDate instances inherit stuff from Date via a prototype.

 * incomplete we might be missing some non-standard methods. This can result in errors like:
