Description
Steps to reproduce:
- Create a TestService that will contain a single property router = inject(Router)
- Configure @angular/build:unit-test runner to include providersFile
- Export [TestService] from it
- Create a Test component that will inject this service: service = inject(TestService)
ng test will fail with the following error for all specs:
FAIL project (chromium) path/to/some.spec.ts [ path/to/some.spec.ts ]
Error: Failed to import test file /project/root/init-testbed.js
Caused by: Error: The injectable '_PlatformLocation' needs to be compiled using the JIT compiler, but '@angular/compiler' is not available.
The injectable is part of a library that has been partially compiled.
However, the Angular Linker has not processed the library such that JIT compilation is used as fallback.
Ideally, the library is processed using the Angular Linker to become fully AOT compiled.
Alternatively, the JIT compiler should be loaded by bootstrapping using '@angular/platform-browser-dynamic' or '@angular/platform-server',
or manually provide the compiler with 'import "@angular/compiler";' before bootstrapping.

If you remove injection of the TestService from the Test component all the specs will start to pass.
