angular - nyc + cypress + angular 前缀为 webpack:?

Question

如何设置 istanbuls nyc 通过 cypress 测试对 Angular 转译代码运行测试覆盖率？

我通过 编译代码ng build，它出现在build/client/目录中，我还编译了我的 cypress 测试，它们出现在build/cypress/. build/cypress/然后我通过以下命令运行 cypress 测试：

npx tsc --project tsconfig.client.test.json
npx ng build
npx nyc --nycrc-path=./.nycrc.client.json cypress run --config reporter=spec

我的.nycrc.client.json文件：

{
    "branches": 0,
    "lines": 0,
    "functions": 0,
    "statements": 0,
    "check-coverage": true,
    "exclude-after-remap": false,
    "reporter": ["text", "html"],
    "clean": true,
    "cache": false,
    "all": true
    "report-dir": "./results/coverage/client",
    "include": [
        "build/client/**/*.js",
        "build/cypress/**/*.js"
    ],
    "exclude": [
        "build/client/es2015-polyfills.js",
        "build/client/polyfills.js",
        "build/client/runtime.js",
        "build/client/styles.js",
        "build/client/vendor.js"
    ]
}

控制台中的覆盖率报告：

为什么这里会涉及到 webpack？

此外，它指出从未使用过的测试文件：

这是来自控制台的测试报告，显示两者都被击中：

为覆盖范围生成的 html 也不正确：
