/**
 * @description
 *
 * Sets up the router to be used for testing.
 *
 * The modules sets up the router to be used for testing.
 * It provides spy implementations of `Location` and `LocationStrategy`.
 *
 * @usageNotes
 * ### Example
 *
 * ```ts
 * beforeEach(() => {
 *   TestBed.configureTestingModule({
 *     imports: [
 *       RouterModule.forRoot(
 *         [{path: '', component: BlankCmp}, {path: 'simple', component: SimpleCmp}]
 *       )
 *     ]
 *   });
 * });
 * ```
 *
 * @publicApi
 * @deprecated Use `provideRouter` or `RouterModule`/`RouterModule.forRoot` instead.
 * This module was previously used to provide a helpful collection of test fakes,
 * most notably those for `Location` and `LocationStrategy`.  These are generally not
 * required anymore, as `MockPlatformLocation` is provided in `TestBed` by default.
 * However, you can use them directly with `provideLocationMocks`.
