单元测试出错使用Karma和Jasmine进行角度代码 - 执行0 of 0 ERROR

Question

我试图用Karma和Jasmine对我的Angular代码进行单元测试。导航到项目文件夹后，我按照上述顺序执行了以下命令：

npm install --save-dev jasmine （用于安装Jasmine）
npm install --save-dev karma （用于安装Karma）
npm install --save-dev karma-jasmine （用于安装Karma依赖项）
业力初始

之后当我尝试运行业力开始时，我收到以下错误，其中显示执行0 0错误并且没有具体内容。

我为什么要这样做的任何线索？我还在下面添加了我的karma.config.js和spec-bundle.js文件内容。

我的karma.config.js文件：

＆＃13;

＆＃13;

   // Karma configuration file, see link for more information
// https://karma-runner.github.io/0.13/config/configuration-file.html

module.exports = function (config) {
config.set({
    basePath: '.',
    frameworks: ['jasmine'],
    files: [
        '../../wwwroot/dist/vendor.js',
        './boot-tests.ts'
    ],
    preprocessors: {
        './boot-tests.ts': ['webpack']
    },
    reporters: ['progress'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    //browsers: ['PhantomJS'], // use headless browswer
    browsers: [
        'Chrome',
        'Chrome_with_debugging'
    ],

    customLaunchers: {

        Chrome_with_debugging: {
            base: 'Chrome',
            //chromeDataDir: path.resolve(__dirname, '.chrome'),
            flags: ['--remote-debugging-port=9333'],
            displayName: 'Chrome with remote debugging'
        }
    },
    mime: { 'application/javascript': ['ts', 'tsx'] },
    // Which plugins to enable defaults to karma-*

    singleRun: false,
    webpack: require('../../webpack.config.js')().filter(config => config.target !== 'node'), // Test against client bundle, because tests run in a browser
    webpackMiddleware: { stats: 'errors-only' }
});
};

＆＃13;

＆＃13;

＆＃13;

我的spec-bundle.js文件：

＆＃13;

＆＃13;

/*
 * When testing with webpack and ES6, we have to do some extra
 * things to get testing to work right. Because we are gonna write tests
 * in ES6 too, we have to compile those as well. That's handled in
 * karma.conf.js with the karma-webpack plugin. This is the entry
 * file for webpack test. Just like webpack will create a bundle.js
 * file for our client, when we run test, it will compile and bundle them
