  Perhaps you are missing some plugin?

Answer 1

我能够弄清楚如何在angular-cli中使用记者

我更新了Karma配置文件(karma.conf.js),如下所示

require('karma-jasmine-html-reporter'),

和

reporters: config.angularCli && config.angularCli.codeCoverage
              ? ['progress', 'karma-remap-istanbul', 'kjhtml']
              : ['progress', 'kjhtml'],

然后运行以下命令来安装插件

npm install karma-jasmine-html-reporter --save-dev

然后我跑了

ng test --code-coverage

它给我一个这样的报告
