Angular Mock Backend

Angular Mock Backend is

1. An AngularJS module to mock some (or all) server requests (optionally with delay) for backend-less development.
2. A Protractor module to help test client by mocking some (or all) server requests (optionally with delay).

This module provides functionality somewhat similar to that provided by ngMockE2E $httpBackend. But it does not use ngMockE2E $httpBackend for its implementation.

Installation

npm install angular-mock-backend --save-dev
bower install angular-mock-backend --save-dev

Example

Backend-less Development

Include provided mock-angular.js in your index.html and use vinkaga.mockBackend as your application dependency. Then include the following JavaScript

var mocks = [
    [['get', '/users', undefined, undefined, undefined], 200, {data:[
        {firstName: 'john', lastName: 'doe'},
        {firstName: 'angular', lastName: 'js'}
    ]}]
];
angular.module('vinkaga.mockBackend').constant('vinkaga.mockBackend.mock', mocks);

This will mock GET for /users with the specified data and 200ms delay. For a full working example, see example-backend-less.

Protractor Tests

In your Protractor test script, insert the following code before tests

var mock = require('angular-mockBackend');
mock.mock([
	[['get', '/users', undefined, undefined, undefined], 200, {data:[
    	{firstName: 'john', lastName: 'doe'},
    	{firstName: 'angular', lastName: 'js'}
    ]}],
]);

This will mock GET for /users with the specified data and 200ms delay in Protractor tests. For a full working example, see example-protractor.

API

Mock Definitions

Array of individual mock definitions, where each mock definition itself is an array of

[config, delay, response]

config

Either an array or function as follows

[method, url, params, data, headers]
// or
function(method, url, params, data, headers) {...}

If config definition is a function, the third parameter of mock definition (response) is ignored. Instead the value returned by the function is used in place of response.

delay

A number in milliseconds. Negative numbers will have an unpredictable effect.

response

If config is specified as a function, it's the value returned by the config function. Otherwise, it is the third parameter of the mock definition. It is treated as follows

Value	Description
object	Matching requests are mocked and delay is applied. The returned data is response.data and the returned status is response.status.
truthy but not object	Matching requests are passed to the server after applying the delay.
falsy	Matching requests are not affected.

Backend-less Development

For backend-less development, use mock definitions as follows

angular.module('vinkaga.mockBackend').constant('vinkaga.mockBackend.mock', <array of mock definitions>);

Protractor Tests

For Protractor tests, use mock definitions as follows

var mock = require('angular-mockBackend');
mock.mock(<array of mock definitions>);
