Angular's `HttpClient` testing utilities play nicely with PendingTasks. Register `provideHttpClient()` and `provideHttpClientTesting()` alongside the Query provider and flush responses through `HttpTestingController`:

```ts
TestBed.configureTestingModule({
imports: [HttpClientTestingModule],
providers: [provideTanStackQuery(queryClient)],
providers: [
provideHttpClient(),
provideHttpClientTesting(),
provideTanStackQuery(queryClient),
],
})

const httpCtrl = TestBed.inject(HttpTestingController)
