All we really need is * to verify whether a certain request has been sent or not, or alternatively just let the * application make requests, respond with pre-trained responses and assert that the end result is * what we expect it to be. * * This mock implementation can be used to respond with static or dynamic responses via the * `expect` and `when` apis and their shortcuts (`expectGET`, `whenPOST`, etc). * * When an Angular application needs some data from a server, it calls the $http service, which * sends the request to a real server using $httpBackend service. With dependency injection, it is * easy to inject $httpBackend mock (which has the same API as $httpBackend) and use it to verify * the requests and respond with some testing data without sending a request to a real server. * * There are two ways to specify what test data should be returned as http responses by the mock * backend when the code under test makes http requests: * * - `$httpBackend.expect` - specifies a request expectation * - `$httpBackend.when` - specifies a backend definition * * * ## Request Expectations vs Backend Definitions * * Request expectations provide a way to make assertions about requests made by the application and * to define responses for those requests. The test will fail if the expected requests are not made * or they are made in the wrong order. * * Backend definitions allow you to define a fake backend for your application which doesn't assert * if a particular request was made or not, it just returns a trained response if a request is made. * The test will pass whether or not the request gets made during testing. * * * <table class="table"> * <tr><th width="220px"></th><th>Request expectations</th><th>Backend definitions</th></tr> * <tr> * <th>Syntax</th> * <td>.expect(...).respond(...)</td> * <td>.when(...).respond(...)</td> * </tr> * <tr> * <th>Typical usage</th> * <td>strict unit tests</td> * <td>loose (black-box) unit testing</td> * </tr> * <tr> * <th>Fulfills multiple requests</th> * <td>NO</td> * <td>YES</td> * </tr> * <tr> * <th>Order of requests matters</th> * <td>YES</td> * <td>NO</td> * </tr> * <tr> * <th>Request required</th> * <td>YES</td> * <td>NO</td> * </tr> * <tr> * <th>Response required</th> * <td>optional (see below)</td> * <td>YES</td> * </tr> * </table> * * In cases where both backend definitions and request expectations are specified during unit * testing, the request expectations are evaluated first. * * If a request expectation has no response specified, the algorithm will search your backend * definitions for an appropriate response. * * If a request didn't match any expectation or if the expectation doesn't have the response * defined, the backend definitions are evaluated in sequential order to see if any of them match * the request. The response from the first matched definition is returned. * * * ## Flushing HTTP requests * * The $httpBackend used in production always responds to requests asynchronously. If we preserved * this behavior in unit testing, we'd have to create async unit tests, which are hard to write, * to follow and to maintain. But neither can the testing mock respond synchronously; that would * change the execution of the code under test. For this reason, the mock $httpBackend has a * `flush()` method, which allows the test to explicitly flush pending requests. This preserves * the async api of the backend, while allowing the test to execute synchronously. * * * ## Unit testing with mock $httpBackend * The following code shows how to setup and use the mock backend when unit testing a controller. * First we create the controller under test: * ```js // The module code angular .module('MyApp', []) .controller('MyController', MyController); // The controller code function MyController($scope, $http) { var authToken; $http.get('/auth.py').then(function(response) { authToken = response.headers('A-Token'); $scope.user = response.data; }); $scope.saveMessage = function(message) { var headers = { 'Authorization': authToken }; $scope.status = 'Saving...'; $http.post('/add-msg.py', message, { headers: headers } ).then(function(response) { $scope.status = ''; }).catch(function() { $scope.status = 'Failed...'; }); }; } ``` * * Now we setup the mock backend and create the test specs: * ```js // testing controller describe('MyController', function() { var $httpBackend, $rootScope, createController, authRequestHandler; // Set up the module beforeEach(module('MyApp')); beforeEach(inject(function($injector) { // Set up the mock http service responses $httpBackend = $injector.get('$httpBackend'); // backend definition common for all tests authRequestHandler = $httpBackend.when('GET', '/auth.py') .respond({userId: 'userX'}, {'A-Token': 'xxx'}); // Get hold of a scope (i.e. the root scope) $rootScope = $injector.get('$rootScope'); // The $controller service is used to create instances of controllers var $controller = $injector.get('$controller'); createController = function() { return $controller('MyController', {'$scope' : $rootScope }); }; })); afterEach(function() { $httpBackend.verifyNoOutstandingExpectation(); $httpBackend.verifyNoOutstandingRequest(); }); it('should fetch authentication token', function() { $httpBackend.expectGET('/auth.py'); var controller = createController(); $httpBackend.flush(); }); it('should fail authentication', function() { // Notice how you can change the response even after it was set authRequestHandler.respond(401, ''); $httpBackend.expectGET('/auth.py'); var controller = createController(); $httpBackend.flush(); expect($rootScope.status).toBe('Failed...'); }); it('should send msg to server', function() { var controller = createController(); $httpBackend.flush(); // now you don’t care about the authentication, but // the controller will still send the request and // $httpBackend will respond without you having to // specify the expectation and response for this request $httpBackend.expectPOST('/add-msg.py', 'message content').respond(201, ''); $rootScope.saveMessage('message content'); expect($rootScope.status).toBe('Saving...'); $httpBackend.flush(); expect($rootScope.status).toBe(''); }); it('should send auth header', function() { var controller = createController(); $httpBackend.flush(); $httpBackend.expectPOST('/add-msg.py', undefined, function(headers) { // check if the header was sent, if it wasn't the expectation won't // match the request and the test will fail return headers['Authorization'] == 'xxx'; }).respond(201, ''); $rootScope.saveMessage('whatever'); $httpBackend.flush(); }); }); ``` * * ## Dynamic responses * * You define a response to a request by chaining a call to `respond()` onto a definition or expectation. * If you provide a **callback** as the first parameter to `respond(callback)` then you can dynamically generate * a response based on the properties of the request. * * The `callback` function should be of the form `function(method, url, data, headers, params)`. * * ### Query parameters * * By default, query parameters on request URLs are parsed into the `params` object. So a request URL * of `/list?q=searchstr&orderby=-name` would set `params` to be `{q: 'searchstr', orderby: '-name'}`. * * ### Regex parameter matching * * If an expectation or definition uses a **regex** to match the URL, you can provide an array of **keys** via a * `params` argument. The index of each **key** in the array will match the index of a **group** in the * **regex**. * * The `params` object in the **callback** will now have properties with these keys, which hold the value of the * corresponding **group** in the **regex**. * * This also applies to the `when` and `expect` shortcut methods. * * * ```js * $httpBackend.expect('GET', /\/user\/(.+)/, undefined, undefined, ['id']) * .respond(function(method, url, data, headers, params) { * // for requested url of '/user/1234' params is {id: '1234'} * }); * * $httpBackend.whenPATCH(/\/user\/(.+)\/article\/(.+)/, undefined, undefined, ['user', 'article']) * .respond(function(method, url, data, headers, params) { * // for url of '/user/1234/article/567' params is {user: '1234', article: '567'} * }); * ``` * * ## Matching route requests * * For extra convenience, `whenRoute` and `expectRoute` shortcuts are available. These methods offer colon * delimited matching of the url path, ignoring the query string. This allows declarations * similar to how application routes are configured with `$routeProvider`. Because these methods convert * the definition url to regex, declaration order is important. Combined with query parameter parsing, * the following is possible: * ```js $httpBackend.whenRoute('GET', '/users/:id') .respond(function(method, url, data, headers, params) { return [200, MockUserList[Number(params.id)]]; }); $httpBackend.whenRoute('GET', '/users') .respond(function(method, url, data, headers, params) { var userList = angular.copy(MockUserList), defaultSort = 'lastName', count, pages, isPrevious, isNext; // paged api response '/v1/users?page=2' params.page = Number(params.page) || 1; // query for last names '/v1/users?q=Archer' if (params.q) { userList = $filter('filter')({lastName: params.q}); } pages = Math.ceil(userList.length / pagingLength); isPrevious = params.page > 1; isNext = params.page < pages; return [200, { count: userList.length, previous: isPrevious, next: isNext, // sort field -> '/v1/users?sortBy=firstName' results: $filter('orderBy')(userList, params.sortBy || defaultSort) .splice((params.page - 1) * pagingLength, pagingLength) }]; }); ``` */ angular.mock.$HttpBackendProvider = function() { this.$get = ['$rootScope', '$timeout', createHttpBackendMock]; }; /** * General factory function for $httpBackend mock. * Returns instance for unit testing (when no arguments specified): * - passing through is disabled * - auto flushing is disabled * * Returns instance for e2e testing (when `$delegate` and `$browser` specified): * - passing through (delegating request to real backend) is enabled * - auto flushing is enabled * * @param {Object=} $delegate Real $httpBackend instance (allow passing through if specified) * @param {Object=} $browser Auto-flushing enabled if specified * @return {Object} Instance of $httpBackend mock */ function createHttpBackendMock($rootScope, $timeout, $delegate, $browser) { var definitions = [], expectations = [], responses = [], responsesPush = angular.bind(responses, responses.push), copy = angular.copy; function createResponse(status, data, headers, statusText) { if (angular.isFunction(status)) return status; return function() { return angular.isNumber(status) ?

Therefore we can test the generated answer * expect(DeepThought.answer).toBe(42); * })); * * it("has calculated the answer within the expected time", inject(function(DeepThought) { * expect(DeepThought.runTimeMillennia).toBeLessThan(8000); * })); * * it("has double checked the answer", inject(function(DeepThought) { * expect(DeepThought.absolutelySureItIsTheRightAnswer).toBe(true); * })); * * }); * * ``` */ module.sharedInjector = function() { if (!(module.$$beforeAllHook && module.$$afterAllHook)) { throw Error("sharedInjector() cannot be used unless your test runner defines beforeAll/afterAll"); } var initialized = false; module.$$beforeAllHook(function() { if (injectorState.shared) { injectorState.sharedError = Error("sharedInjector() cannot be called inside a context that has already called sharedInjector()"); throw injectorState.sharedError; } initialized = true; currentSpec = this; injectorState.shared = true; }); module.$$afterAllHook(function() { if (initialized) { injectorState = new InjectorState(); module.$$cleanup(); } else { injectorState.sharedError = null; } }); }; module.$$beforeEach = function() { if (injectorState.shared && currentSpec && currentSpec != this) { var state = currentSpec; currentSpec = this; angular.forEach(["$injector","$modules","$providerInjector", "$injectorStrict"], function(k) { currentSpec[k] = state[k]; state[k] = null; }); } else { currentSpec = this; originalRootElement = null; annotatedFunctions = []; } }; module.$$afterEach = function() { if (injectorState.cleanupAfterEach()) { module.$$cleanup(); } }; module.$$cleanup = function() { var injector = currentSpec.$injector; annotatedFunctions.forEach(function(fn) { delete fn.$inject; }); angular.forEach(currentSpec.$modules, function(module) { if (module && module.$$hashKey) { module.$$hashKey = undefined; } }); currentSpec.$injector = null; currentSpec.$modules = null; currentSpec.$providerInjector = null; currentSpec = null; if (injector) { // Ensure `$rootElement` is instantiated, before checking `originalRootElement` var $rootElement = injector.get('$rootElement'); var rootNode = $rootElement && $rootElement[0]; var cleanUpNodes = !originalRootElement ?

The inject() creates new * instance of {@link auto.$injector $injector} per test, which is then used for * resolving references. * * * ## Resolving References (Underscore Wrapping) * Often, we would like to inject a reference once, in a `beforeEach()` block and reuse this * in multiple `it()` clauses. To be able to do this we must assign the reference to a variable * that is declared in the scope of the `describe()` block. Since we would, most likely, want * the variable to have the same name of the reference we have a problem, since the parameter * to the `inject()` function would hide the outer variable. * * To help with this, the injected parameters can, optionally, be enclosed with underscores. * These are ignored by the injector when the reference name is resolved. * * For example, the parameter `_myService_` would be resolved as the reference `myService`. * Since it is available in the function body as _myService_, we can then assign it to a variable * defined in an outer scope. * * ``` * // Defined out reference variable outside * var myService; * * // Wrap the parameter in underscores * beforeEach( inject( function(_myService_){ * myService = _myService_; * })); * * // Use myService in a series of tests. * it('makes use of myService', function() { * myService.doStuff(); * }); * * ``` * * See also {@link angular.mock.module angular.mock.module} * * ## Example * Example of what a typical jasmine tests looks like with the inject method. * ```js * * angular.module('myApplicationModule', []) * .value('mode', 'app') * .value('version', 'v1.0.1'); * * * describe('MyApp', function() { * * // You need to load modules that you want to test, * // it loads only the "ng" module by default. * beforeEach(module('myApplicationModule')); * * * // inject() is used to inject arguments of all given functions * it('should provide a version', inject(function(mode, version) { * expect(version).toEqual('v1.0.1'); * expect(mode).toEqual('app'); * })); * * * // The inject and module method can also be used inside of the it or beforeEach * it('should override a version and test the new version is injected', function() { * // module() takes functions or strings (module aliases) * module(function($provide) { * $provide.value('version', 'overridden'); // override version here * }); * * inject(function(version) { * expect(version).toEqual('overridden'); * }); * }); * }); * * ``` * * @param {...Function} fns any number of functions which will be injected using the injector. */ var ErrorAddingDeclarationLocationStack = function(e, errorForStack) { this.message = e.message; this.name = e.name; if (e.line) this.line = e.line; if (e.sourceId) this.sourceId = e.sourceId; if (e.stack && errorForStack) this.stack = e.stack + '\n' + errorForStack.stack; if (e.stackArray) this.stackArray = e.stackArray; }; ErrorAddingDeclarationLocationStack.prototype = Error.prototype; window.inject = angular.mock.inject = function() { var blockFns = Array.prototype.slice.call(arguments, 0); var errorForStack = new Error('Declaration Location'); // IE10+ and PhanthomJS do not set stack trace information, until the error is thrown if (!errorForStack.stack) { try { throw errorForStack; } catch (e) {} } return wasInjectorCreated() ? workFn.call(currentSpec) : workFn; ///////////////////// function workFn() { var modules = currentSpec.$modules || []; var strictDi = !!currentSpec.$injectorStrict; modules.unshift(['$injector', function($injector) { currentSpec.$providerInjector = $injector; }]); modules.unshift('ngMock'); modules.unshift('ng'); var injector = currentSpec.$injector; if (!injector) { if (strictDi) { // If strictDi is enabled, annotate the providerInjector blocks angular.forEach(modules, function(moduleFn) { if (typeof moduleFn === "function") { angular.injector.$$annotate(moduleFn); } }); } injector = currentSpec.$injector = angular.injector(modules, strictDi); currentSpec.$injectorStrict = strictDi; } for (var i = 0, ii = blockFns.length; i < ii; i++) { if (currentSpec.$injectorStrict) { // If the injector is strict / strictDi, and the spec wants to inject using automatic // annotation, then annotate the function here. injector.annotate(blockFns[i]); } try { /* jshint -W040 *//* Jasmine explicitly provides a `this` object when calling functions */ injector.invoke(blockFns[i] || angular.noop, this); /* jshint +W040 */ } catch (e) { if (e.stack && errorForStack) { throw new ErrorAddingDeclarationLocationStack(e, errorForStack); } throw e; } finally { errorForStack = null; } } } }; angular.mock.inject.strictDi = function(value) { value = arguments.length ? !!value : true; return wasInjectorCreated() ? workFn() : workFn; function workFn() { if (value !== currentSpec.$injectorStrict) { if (currentSpec.$injector) { throw new Error('Injector already created, can not modify strict annotations'); } else { currentSpec.$injectorStrict = value; } } } }; function InjectorState() { this.shared = false; this.sharedError = null; this.cleanupAfterEach = function() { return !this.shared || this.sharedError; }; } })(window.jasmine || window.mocha); })(window, window.angular);
