`unit-test` builder resolves include paths relative to sourceRoot instead of project root, breaking secondary entry points tests

まず、@angular/build:unit-test builder を使用して最小再現を実行し、angular.json にあるその include パターンがどのように解決されるかを調べます。示されているパス my-sub-package/**/*.spec.ts を含むライブラリで動作を確認します。パターンがプロジェクトルートを基準に解決され、ng test が ../ によるパストラバーサルなしでセカンダリエントリポイントのテストを検出できれば完了です。

Description

When using the @angular/build:unit-test builder in a library project that contains Secondary Entry Points (sub-packages), the builder incorrectly resolves the glob patterns defined in the include array (inside angular.json) relative to the project's sourceRoot (usually .../src) instead of the project's root.

Because the unit-test builder anchors include patterns to sourceRoot, it cannot discover test files located in secondary entry points unless developers use relative path traversal (for example, ../my-sub-package/**/*.spec.ts).

Minimal Reproduction

Create an Angular library project.
2. Generate a secondary entry point inside the library root (for example, projects/my-lib/my-sub-package/).
3. Add a unit test inside the secondary entry point:

projects/my-lib/my-sub-package/my-sub.spec.ts

4. Configure the test target in angular.json using @angular/build:unit-test:

   {
     "options": {
       "include": [
         "**/*.spec.ts",
         "my-sub-package/**/*.spec.ts"
       ],
       "tsConfig": "projects/my-lib/tsconfig.spec.json"
     }
   }
   

5. Run:

   ng test
   

Exception or Error

The builder should resolve the include patterns relative to the project's root, or otherwise recognize ng-packagr secondary entry points, allowing patterns such as:

{
  "include": [
    "**/*.spec.ts",
    "my-sub-package/**/*.spec.ts"
  ]
}

to correctly match test files located in:

projects/my-lib/my-sub-package/

Workaround

Currently, developers must escape the sourceRoot directory by using a parent path segment in angular.json:

{
  "options": {
    "include": [
      "**/*.spec.ts",
      "../my-sub-package/**/*.spec.ts"
    ],
    "tsConfig": "projects/my-lib/tsconfig.spec.json"
  }
}
