Routing Error

Hello All,

I am facing one issue related to routing, I am having parent routing where I want to load few data which is common to all child routs. And I am seeing the url is changing in browser but its not actually loading the child component.

Here is AppRoutingModule:
import { NgModule } from ‘@angular/core’;

import { PreloadAllModules, RouterModule, Routes } from ‘@angular/router’;

const routes: Routes = [

{ path: ‘’, redirectTo: ‘testseries’, pathMatch: ‘full’ },

{

path: 'login',

loadChildren: () => import('./Page/login/login.module').then( m => m.LoginPageModule)

},

{

path: 'course',

loadChildren: () => import('./Page/course/course.module').then( m => m.CoursePageModule)

},

{

path: 'testseries',

loadChildren: () => import('./Page/test/test.module').then( m => m.TestPageModule)

}

];

@NgModule({

imports: [

RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules })

],

exports: [RouterModule]

})

export class AppRoutingModule { }

Its navigating to testseries and its loading file in testseries component I am loading few data which is required for all child routs

import { NgModule } from ‘@angular/core’;

import { Routes, RouterModule } from ‘@angular/router’;

import { TestPage } from ‘./test.page’;

const routes: Routes = [

{

path: 'exams',

component: TestPage,

children: [

  { path: '', redirectTo: 'examlisting', pathMatch: 'full' },

  {

    path: 'examlisting',

    loadChildren: () => import('./examlisting/examlisting.module').then(m => m.ExamlistingPageModule)

  },

  {

    path: 'testlisting',

    loadChildren: () => import('../../Page/test/testlisting/testlisting.module').then(m => m.TestlistingPageModule)

  }

]

},

// {

// path: ‘’,

// redirectTo: ‘/testseries/exams/examlisting’,

// pathMatch: ‘full’

// }

];

@NgModule({

imports: [RouterModule.forChild(routes)],

exports: [RouterModule],

})

export class TestPageRoutingModule { }

in the browser I am seeing the URL is getting changed to http://localhost:/testseries/exams/examlisting but it not loading examlisting component. Can someone help me in this what mistake I am doing.
