【中文标题】Angular 6 代码覆盖率...如何在应用程序的代码覆盖率中排除本地库？【英文标题】：Angular 6 Code Coverage... how to exclude local library in code coverage of application? 【发布时间】：2019-01-23 19:10:35 【问题描述】：我有一个具有以下基本结构的 Angular 工作区：
/projects
-- /admin <-- angular application
-- /core <-- library
这些是通过运行ng generate application admin 和ng generate library core...相当直接生成的。
在运行ng test core 时，核心库的覆盖率约为 90%。
当运行ng test admin 时，管理应用程序应该有大约 90% 的覆盖率，但覆盖率报告包括核心文件（没有相应的测试）。示例：

admin/src/app 行显示 admin 项目的覆盖率为 94.55% (...)，但这些数字并未反映在摘要中。
我明白为什么它试图包含文件（它们正在被导入）......但我该如何排除它们？我曾尝试修改 admin/ 中的 tsconfig.spec.json 文件以排除这些文件，但这不起作用。当我修改根 tsconfig.json 文件以删除库的“路径”（别名为 @martzcodes/core 并以这种方式导入）时，我收到了相应的导入警告。我不应该嘲笑我所有的库......
Typescript 版本 2.9.2，@angular/cli 6.1.3
【问题讨论】：
【参考方案1】：在 angular.json 中使用codeCoverageExclude test.options 像这样：
"codeCoverageExclude": [
"admin/**",
]
https://github.com/angular/angular-cli/issues/3356
angular cli exclude files/directory for `ng test --code-coverage`
