What could be causing routerLink to malfunction despite correct configuration?

Is routerLink properly placed in the view?

<p><a routerLink="/registration" class="nav-link">Register</a></p>

Checking my app.module

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { HttpClientModule } from '@angular/common/http';
import { Routes, RouterModule } from '@angular/router';
import { CommonModule } from '@angular/common';

import { AppComponent } from './components/app.component';
import { TestStartComponent } from './components/test-start.component';
import { TestListComponent } from './components/test-list.component';
import { RegistrationComponent } from './components/registration.component';


const appRoutes: Routes = [
    { path: '', component: TestListComponent },
    { path: 'teststart/:id', component: TestStartComponent },
    { path: '**', redirectTo: '/' },
    { path: 'registration', component: RegistrationComponent}
];

@NgModule({
    imports: [BrowserModule, [CommonModule], FormsModule, HttpClientModule, RouterModule.forRoot(appRoutes)],
    declarations: [AppComponent, TestListComponent, TestStartComponent, RegistrationComponent],
    bootstrap: [AppComponent]
})

Details about my RegistrationComponent

import { Component, OnInit } from '@angular/core';
import { UserService } from '../services/user.service';
import { User } from '../models/user';
import { Router } from '@angular/router';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { first } from 'rxjs/operators';

@Component({
    templateUrl: '../views/registration.component.html',
    providers: [UserService]
})

export class RegistrationComponent implements OnInit {
    constructor(
        private userService: UserService
    ) { }

    ngOnInit() {
        console.log("Initial method called");
    }

Describing registration.component.html

<p>Initial method called</p>

No response when clicking the link. Other routerLinks are functioning correctly.

Requesting an adjustment to the route configuration:

{ path: '', component: TestListComponent }

Ensure 'pathMatch: 'full'' is added to the above route, and relocate the following route to the end:

{ path: '**', redirectTo: '/' }

The revised route setup should look like this:

    { path: '', component: TestListComponent, pathMatch: 'full' },
    { path: 'teststart/:id', component: TestStartComponent },
    { path: 'registration', component: RegistrationComponent},
    { path: '**', redirectTo: '/' }

As per Angular's official documentation:

Using 'pathMatch: 'full'' ensures a complete URL match. Important for avoiding redirect loops with empty-path routes.

Regarding wildcards, according to the docs:

Router matching notation accepts wildcard (**) which matches any URL. Default is "/".

Note that route order matters; the Angular engine processes routes sequentially from top to bottom to find the correct match.
