routerLink 不会导航到延迟加载模块

我在导航到延迟加载模块中定义的组件时遇到问题。该组件ListComponent在路径“test”下定义（my-routing.module.ts - 延迟加载模块）。每当我单击“测试”按钮（test.component.html）时，我都会收到异常：

NG04002：无法匹配任何路由。URL 段：“测试”。

为什么？

我的app-routing.module.ts如下所示：

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { HomeComponent } from './components/home/home.component';
import { AboutComponent } from './components/about/about.component';
import { DashboardComponent } from './components/dashboard/dashboard.component';
import { AuthGuard } from './auth.gard';
import { ListComponent } from './list.component';
import { TestComponent } from './test/test.component';


const myModule = () => import('./my-routing/my-.module').then(x => x.MyRoutingModule);
const routes: Routes = [
  { path: '', component: TestComponent },
  { path: 'experiment', loadChildren: myModule },

];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

我的my-routing.module.ts是：

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { ListComponent } from '../list.component';
import { TestComponent } from '../test/test.component';

const routes: Routes = [

  { path: 'test', component: ListComponent },

];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class MyRoutingModule { }

我的test.component.html看起来像这样：

<div class="container">
  <div class="row">
    
    <div class="col-1">
      <a [routerLink]="['test']"><button type="button" class="btn btn-primary">
          Test</button></a>
    </div>

  </div>
</div>
