HttpClientTestingModule is deprecated, how to replace it?

After upgrading my application to Angular 18.0.4, my test classes say:

'HttpClientTestingModule' is deprecated. Add provideHttpClientTesting() to your providers instead.

Therefore I adapted my code as follows:

await TestBed.configureTestingModule(
{
imports: [
AssetDetailsComponent,
],
providers: [
// replacement for HttpClientTestingModule:
provideHttpClientTesting()
]
})
.compileComponents();


However, when I run the tests, I get the following error:

NullInjectorError: R3InjectorError(Standalone[AssetDetailsComponent])[InventoryActionService -> InventoryActionService -> _HttpClient -> _HttpClient]:
NullInjectorError: No provider for _HttpClient!


If I use provideHttpClient() instead of provideHttpClientTesting() it works, yet I doubt that this is best practice. What is the correct solution to this issue?
