Command

add, generate

Description

for new project that has selected zoneless, the generated unit test file should follow the guide
https://angular.dev/guide/zoneless#using-zoneless-in-testbed
as it mention

avoid using fixture.detectChanges() when possible
but since the generated ones already have them most people will forget, or not even know that they should instead using fixture.whenStable

Describe the solution you'd like

1. new projects should have the app.spec.ts file use fixture.whenStable
2. generated components should not have fixture.detectChanges() added at beforeEach
3. generated components should have await fixture.whenStable() added at beforeEach

Describe alternatives you've considered
