将karma-coverage添加到ember测试

Question

我发现了一个非常棒的ember测试样本：

https://github.com/toranb/ember-testing-example

我让它运行了，但是我不能让karma-coverage工作，下面是错误：

错误覆盖率: TypeError:无法设置未定义TypeError的属性“covered”：无法设置未定义的属性“covered”

我只更新了karma.conf.js文件和package.json

package.json

{
  "dependencies": {
    "bower": "*",
    "karma-ember-preprocessor": "*",
    "karma-qunit": "*",
    "karma": "0.10",
    "karma-coverage": "~0.1"
  },
  "scripts": {
    "postinstall": "bower install"
  }
}

​

karma.conf.js

module.exports = function(karma) {
    karma.set({
        basePath: 'js',

        files: [
          "vendor/jquery/jquery.min.js",
          "vendor/handlebars/handlebars.js",
          "vendor/ember/ember.js",
          "vendor/jquery-mockjax/jquery.mockjax.js",
          "app.js",
          "tests/*.js",
          "templates/*.handlebars"
        ],

        // coverage reporter generates the coverage
        reporters: ['progress', 'coverage'],

        //logLevel: karma.LOG_ERROR,
        logLevel: karma.LOG_DEBUG,
        browsers: ['PhantomJS'],
        singleRun: true,
        autoWatch: true,

        frameworks: ["qunit"],

        plugins: [
            'karma-qunit',
            'karma-coverage',
            'karma-chrome-launcher',
            'karma-ember-preprocessor',
            'karma-phantomjs-launcher'
        ],

        preprocessors: {
            "**/*.handlebars": ['ember','coverage']
        },

        // optionally, configure the reporter
        coverageReporter: {
            type : 'html',
            dir  : 'coverage/'
        }
    });
};

​

请让我知道我错过了什么。我怀疑我没有正确地配置它，这一行可能是问题所在。

    preprocessors: {
        "**/*.handlebars": ['ember','coverage']
    },

任何帮助都将不胜感激。

​

preprocessors: {
        "**/*.handlebars": 'ember',
        "**/*.js": 'coverage'
    },

以上内容允许您从Karma创建覆盖率报告。

注:这种配置不适用于最新的ES6模块
