<?php

namespace Tests\Browser;

use App\Models\User;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Laravel\Dusk\Browser;
use Tests\DuskTestCase;

class ExampleTest extends DuskTestCase
{
    use DatabaseMigrations;

    /**
     * A basic browser test example.
     *
     * @return void
     */
    public function testExample()
    {
        $user = User::factory()->create(); // 使用工厂创建一个用户

        $this->browse(function (Browser $browser) use ($user) {
            $browser->visit('/register')
                    ->type('email', $user->email) // 使用已存在的电子邮件地址
                    ->type('password', 'password')
                    ->type('password_confirmation', 'password')
                    ->press('Register')
                    ->assertSee('The email has already been taken.'); // 验证是否显示错误信息
        });
