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

Comece executando a reprodução mínima com o builder @angular/build:unit-test e inspecione como os padrões de inclusão dele em angular.json são resolvidos. Verifique o comportamento com uma biblioteca que contenha o caminho mostrado my-sub-package/**/*.spec.ts. Está concluído quando os padrões são resolvidos a partir da raiz do projeto e ng test descobre testes em pontos de entrada secundários sem travessia de caminho por meio de ../.

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"
  }
}
