📝 WalkthroughWalkthroughThe test runner changes from Jest to Vitest. Angular test setup moves into Vitest configuration and spec files. Auth0 Angular and playground specs replace Jest mocks and callback-based timing with Vitest mocks and async/await assertions. Testing documentation reflects the new workflow. ChangesVitest migration
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk:🔵 Low · up to The Vitest migration leaves one playground setup module unused and retains an open asynchronous-navigation test concern. These affect test reliability and future coverage rather than application runtime behavior, but should be addressed or explicitly accepted before relying on the migrated suite.

In `@projects/auth0-angular/src/lib/abstract-navigator.spec.ts`:
- Line 76: Update AbstractNavigator.navigateByUrl to return or await the Promise
from Router.navigateByUrl so callers can reliably await navigation completion;
preserve the test’s assertion timing after
navigator.navigateByUrl('/test-route').
In `@projects/auth0-angular/src/lib/auth.service.spec.ts`:
- Around line 306-309: Update the test containing the isAuthenticated$
subscription to use an async test declaration and await the promise-backed
observable emission, ensuring the expect(value).toBe(true) assertion executes
before the test completes.
- Around line 29-30: Update the firstValueFrom polyfill to reject with RxJS
EmptyError when the source completes without emitting, while resolving the first
emitted value as before; use the existing Observable/take flow and ensure
deleteAuthenticationMethod behavior remains validated against an actual emission
rather than an empty completion.
In `@projects/playground/src/test-setup.ts`:
- Line 1: Replace the Vitest-only setup import in the test setup with Jest
Angular environment initialization using setupZoneTestEnv from
jest-preset-angular/setup-env/zone, ensuring TestBed is initialized before
playground specs run.

Wait for router navigation before asserting Location.
AbstractNavigator.navigateByUrl returns void after calling Router.navigateByUrl, so the await can resolve before navigation completes. Return the router Promise or await an explicit completion signal before asserting Location.
