业力报道总是空洞的

Question

我一直在尝试运行业力报道几天，现在只找到一个空的空白页面，如下所示。

这是我的配置：

var path = require('path');

var webpackConfig = require('./webpack.common');

module.exports = function (config) {
  var _config = {
    basePath: '',
    frameworks: ['jasmine'],
    files: [
      { pattern: './karma-shim.js', watched: false }
    ],
    exclude: [],
    preprocessors: {
      './karma-shim.js': ['webpack', 'sourcemap', 'coverage']
    },
    client: {
      captureConsole: false
    },
    webpack: webpackConfig,

    webpackMiddleware: {
      stats: 'errors-only'
    },

    coverageReporter: {
      dir: 'coverage/',
      reporters: [{
        type: 'json',
        dir: 'coverage',
        subdir: 'json',
        file: 'coverage-final.json'
      }]
    },

    remapIstanbulReporter: {
      src: 'coverage/json/coverage-final.json',
      reports: {
        lcovonly: 'coverage/json/lcov.info',
        html: 'coverage/html',
        'text': null
      },
      timeoutNotCreated: 1000, // default value
      timeoutNoMoreFiles: 1000 // default value
    },

    webpackServer: {
      noInfo: true // please don't spam the console when running in karma!
    },
    reporters: ["mocha", "coverage", "karma-remap-istanbul"],
    port: 9876,
    colors: true,
    logLevel: config.LOG_ERROR,
    autoWatch: false,
    browsers: ['PhantomJS'], // you can also use Chrome

    singleRun: true
  };

  config.set(_config);

};

这是我的karma-shim.js文件

Error.stackTraceLimit = Infinity;
require('es6-shim');
require('reflect-metadata');
require('ts-helpers');
require('zone.js/dist/zone');
require('zone.js/dist/long-stack-trace-zone');
require('zone.js/dist/jasmine-patch');
require('zone.js/dist/async-test');
require('zone.js/dist/fake-async-test');

var appContext = require.context('./app', true, /\.spec\.ts/);
appContext.keys().forEach(appContext);

var testing = require('@angular/core/testing');
var browser = require('@angular/platform-browser-dynamic/testing');

testing.setBaseTestProviders(browser.TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS, browser.TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);

文件夹结构如下：

知道我在这里缺少什么吗？非常感谢。

谢谢

您的业​​力配置显然缺少对来源的引用。

请修改配置如下：

module.exports = function (config) {
    var _config = {
        [...]
        preprocessors: {
            // Remove coverage as preprocessor for your tests - 
            // Istambul (runs coverage behind the scene for karma) will 
            // instrumentate this
            './karma-shim.js': ['webpack', 'sourcemap'],
            // Add path to your source (.js or .ts - depands on your project)
            './index.ts': [ 'coverage' ]
        },
        [...]
    },
    [...]
}

说明：coverage根据您的单元测试测试您的代码 - 您需要为代码提供入口点以获得Karma分析覆盖率。

额外 - 添加karma-coverage插件：

module.exports = function (config) {
    var _config = {
        [...]
        plugins: [
            require( 'karma-coverage' )
        ],
        [...]
    },
    [...]
}

额外 - 业力和打字稿文件：

module.exports = function (config) {
    var _config = {
        [...]
        plugins: [
            require( '@angular/cli/plugins/karma' )
        ],
        [...]
    },
    [...]
    preprocessors: {
        './src/test.ts': [ '@angular/cli' ],
        './index.ts': [ 'coverage' ]
    },
    [...]
    mime: {
       'text/x-typescript': [ 'ts', 'tsx' ]
    },
    [...]
}
