验证规则（required和before_or_equal规则测试已通过） #

<?php

namespace App\Http\Requests\Profile;

use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Validation\Rule;

class UpdateRequest extends FormRequest
{
    //...
    public function rules(): array
    {
        // ...
        'birthday' => 'required|date|before_or_equal:'.now()->subYears(2)->format('Y-m-d'),
        // ...
    }
    // ...
}

测试代码 #

<?php

namespace Tests\Feature\Profile;

use Illuminate\Foundation\Testing\RefreshDatabase;
use Tests\TestCase;

class UpdateTest extends TestCase
{
    use RefreshDatabase;
    private $happyCase = [
        'username' => 'testing123',
        'family_name' => 'Chan',
        'given_name' => 'Diamond',
        'passport_type_id' => 2,
        'passport_number' => 'A1234567',
        'gender' => 'Male',
        'birthday' => '1997-07-01',
    ];
    // ...
    public function test_birthday_is_not_date()
    {
        $data = $this->happyCase;
        $data['birthday'] = 'abc';
        $response = $this->actingAs($this->user)->put(route('profile.update'), $data);
        $response->assertInvalid(['birthday' => 'The birthday field must be a valid date.']);
    }
    // ...
}

环境差异 #

本地Laravel 10环境测试可正常通过，仅在Laravel 10升级至11的PR中出现此错误。
