Reading Angular runtime routes in ng test

Angular AOT does not prevent a test from reading routes registered with the router. Inject Router and use its config property. This is especially useful when the route tree is assembled through provideRouter, providers, or runtime configuration rather than being safe to import directly in Node.js.

Install the package in the Angular application, then add this service:

import { Injectable } from '@angular/core';
import { Router } from '@angular/router';
import { routesToPaths } from 'ngx-seo-kit';

@Injectable({ providedIn: 'root' })
export class RouteExportService {
  constructor(private readonly router: Router) {}

  sitemapPaths(): string[] {
    return routesToPaths(this.router.config);
  }
}

Test it using the application's actual route provider:

import { TestBed } from '@angular/core/testing';
import { provideRouter } from '@angular/router';
import { APP_ROUTES } from './app.routes';
import { RouteExportService } from './route-export.service';

describe('RouteExportService', () => {
  it('exports public URLs from the Angular router config', async () => {
    TestBed.configureTestingModule({
      providers: [provideRouter(APP_ROUTES)],
    });

    const service = TestBed.inject(RouteExportService);
    const paths = await service.sitemapPaths();

    console.log('[ngx-seo-kit:routes]', JSON.stringify(paths));
    expect(paths).toContain('/');
    expect(paths).toContain('/admin/users');
  });
});

Run it with:

ng test --include='**/route-export.service.spec.ts' --watch=false

discoverRoutes() creates src/app/route-export.service.ts and src/app/route-export.service.spec.ts automatically when either file is missing, then runs the test from the Angular project root. It never overwrites existing generated files.

routesToPaths follows eager children arrays, excludes redirects, wildcard routes, and parameterised paths, and returns normalized URL paths. Lazy loadChildren children are not loaded by this test; use the package's build-time discoverRoutes() source scanner for those routes.
