router

Description

If a project upgrades to Angular 17.3.0, RouterTestingModule's deprecation (#54466) will cause a ton of warnings/errors if that project has linter rules against deprecated APIs. Can Angular provide an official migration for this?

Proposed solution

Automatically migrate from this:

imports: [
  ...
  RouterTestingModule.withRoutes([]),
  ...
],

to this if the component is not standalone:

imports: [
  ...
  RouterModule.forRoot([]),
  ...
],

or to this if the component is standalone:

providers: [
  ...
  provideRouter([]),
  ...
],

and fix the relevant import statements.

Alternatives considered

Manually migrate everything.
