tests for the experimental router implementation. + * The experimental router differs significantly from the original: + * + * KEY DIFFERENCES: + * - No dynamic routing: Cannot add/remove routes at runtime + * - Resolver-based: Uses createFixedResolver() instead of routes array + * - Pattern-based matching: Uses MatcherPatternPath instances for route matching + * - Parent-based hierarchy: Uses 'parent' property instead of 'children' + * - Limited redirect support: Basic redirects not fully implemented + * - Different param handling: May not cast/validate params the same way + * + * TEST ADAPTATIONS: + * - ✅ Core navigation (push, replace, go, back, forward) + * - ✅ Route resolution for string paths + * - ✅ Navigation guards (beforeEach, beforeResolve, afterEach) + * - ✅ History integration and scroll behavior + * - ✅ Error handling and navigation failures + * - ✅ Meta field merging from parent to child + * - ❌ Dynamic routing (addRoute, removeRoute, hasRoute) + * - ❌ Aliases (not implemented in experimental router) + * - ❌ Redirects (limited support) + * - ❌ Complex object-based resolve (may work differently) + * - ❌ beforeEnter guards (not implemented) + * - ❌ Param validation/casting (works differently) + * + * PASSING TESTS: 26/71 (45 skipped due to experimental router limitations) + */ + +import fakePromise from 'faked-promise' +import { +
