我已经弹出了我的Angular-CLI项目，无法获得任何代码覆盖范围。我尝试了各种软件包和配置，似乎找不到正确的组合。当我运行npm run test时，测试确实成功运行，并显示Chrome浏览器输出。我只想能够设置阈值并获取覆盖范围。

我在弹出的CLI应用程序中将以下内容添加到我的 karma.conf.js 文件中，以使覆盖范围工作。
coverageIstanbulReporter: {
reports: [ 'html', 'lcovonly', 'text-summary' ],
fixWebpackSourcePaths: true
},
angularCli: {
environment: 'dev',
codeCoverage: true
},
reporters: config.angularCli && config.angularCli.codeCoverage
? ['progress', 'coverage-istanbul']
: ['progress', 'kjhtml'],
与原始的唯一区别是在覆盖范围记者中添加text-summary，codeCoverage: true下的CC_3和reporters逻辑。
现在，当我运行npm run test时，我会在下面获得一个文本摘要，以及 coverage 文件夹中的html报告。
=============================== Coverage summary ===============================
Statements : 100% ( 28/28 )
Branches : 100% ( 0/0 )
Functions : 100% ( 6/6 )
Lines : 100% ( 24/24 )
================================================================================
如果要关闭覆盖范围，请将codeCoverage设置为false false。
这是我发现在弹出 CLI应用程序中使用覆盖范围报告的唯一方法。
我刚刚使用CLI版本1.5.4在新弹出的应用程序上进行了测试，它起作用了。
代码覆盖范围为一个参数，默认情况下为其false。在您的情况下，您正在通过--code-coverage，但不传递任何值，因此默认情况下为false。
尝试这个
ng test -c karma.conf.js --code-coverage true --single-run true
您也可以将其添加到您的软件包中。
" test"：" ng测试 - 代码覆盖true"
然后npm run test
