如何从Angular.js模块获取资源进行茉莉花测试 [英] How do I get a resource from an Angular.js module for a jasmine test

问题描述

我有一个包含项目资源的模块，代码如下:

I have a module that contains resources for a project, and the code looks like this:

editor_services.js

var editorServices = angular.module('editorServices', ['ngResource']);
editorServices.factory('Project', ['$resource', '$http',function($resource, $http){ 
//...etc

现在，我想为期望项目资源作为参数的控制器编写测试.如何从editorServices变量中获取由该工厂创建的项目资源的实例?

now I would like to write tests for a controller that expects a project resource as an argument. How can I get an instance of the project resource that is created by this factory out of the editorServices variable?

推荐答案

下面是一个有效的示例，该示例将如何以角度测试资源(或http) http://plnkr.co/edit/kK5fDFIVpyZTInH1c6Vh?p=preview

Here is a working example how one would test Resources (or http) in angular http://plnkr.co/edit/kK5fDFIVpyZTInH1c6Vh?p=preview

基本设置是:

在测试中

1. 加载angular-mocks.js.这将$httpBackend替换为模拟版本.请参阅: http://docs.angularjs.org/api/ngMock .$ httpBackend

1. load angular-mocks.js in your test. This replaces the $httpBackend with mock version. See: http://docs.angularjs.org/api/ngMock.$httpBackend

在测试调用$httpBackend.expect()中创建要被模拟的期望.

In your test call $httpBackend.expect() to create expectation to be mocked out.

要模拟服务器响应时，请调用$httpBackend.flush()

When you want to simulate server response call $httpBackend.flush()

有一个警告，茉莉花的普通.toEqual()不能与$resource配合使用，因此您必须像这样创建自定义匹配器:

There is a caveat that normal .toEqual() from jasmine dose not work with $resource so you have to create custom matcher like so:

  beforeEach(function() {
    this.addMatchers({
      // we need to use toEqualData because the Resource hase extra properties 
      // which make simple .toEqual not work.
      toEqualData: function(expect) {
        return angular.equals(expect, this.actual);
      }
    });
  });
