CoffeeScript 代码单元测试 AngularJS - Jasmine - Karma

Question

我正在尝试为使用 CoffeeScript 编写的 Ionic 项目的控制器和服务编写单元测试。我选择使用 Karma 和 Jasmine。问题是它不解释 coffeeScript。这就是为什么我使用这个插件 karma-coffee-preprocessor 以便它成为可能。不知道我做的对不对

我用命令安装了插件； npm install --save-dev karma-coffee-preprocessor 然后我配置我的测试配置文件如下：

module.exports = function(config) {
  config.set({

    basePath: '',
    frameworks: ['jasmine'],
    files: [
        '../bower_components/angular/angular.js',
        '../bower_components/angular-ui-router/release/angular-ui-router.js',
        '../bower_components/angular-mocks/angular-mocks.js',
        '../src/scripts/**/*.coffee',
        'unit-tests/**/*.js'
    ],

    exclude: [
    ],

    preprocessors: {
        '../src/scripts/**/*.coffee': ['coffee']
    },

    coffeePreprocessor: {
      options: {
        bare: true,
        sourceMap: false
      },
      transformPath: function(path) {
        return path.replace(/\.coffee$/, '.js')
      }
    },

    reporters: ['progress'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_DEBUG,
    autoWatch: true,
    browsers: ['PhantomJS'],
    singleRun: false,
    concurrency: Infinity
  })
}

但是当我尝试开始我的测试时出现了这个错误：

 Can not load "coffee", it is not registered!
  Perhaps you are missing some plugin?

      throw error('No provider for "' + name + '"!');
      ^

    at Function.Module.runMain (module.js:447:10)
    at startup (node.js:146:18)

谁能帮帮我？我在进行这些单元测试时遇到了麻烦，而且我不知道我做事的方式是否正确。

首先您需要通过 npm 安装 jasmine 框架并将其添加到 karma 配置文件中的框架集合中：

$ npm install karma-jasmine --save-dev

然后添加：

frameworks: ['jasmine']

到 karma 配置文件。
