模拟Laravel自定义验证规则类不起作用 [英] Mocking Laravel custom validation rule class not working

问题描述

我正在表单提交中实施新的自定义验证规则.但是我想在单元测试中绕过验证规则.下面是验证规则和单元测试类的简化.我想念什么?

I'm implementing a new custom validation rule in form submit. But I want to bypass the validation rule in unit testing. Below is the simplified of the validation rule and unit test class. What am I missing?

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;

class Captcha implements Rule
{
    public function passes($attribute, $value)
    {
        // assuming will always return false in testing
        // works fine when true
        return false; 
    }

    public function message()
    {
        return 'Captcha error! Try again later or contact site admin.';
    }
}

use Tests\TestCase;
use App\Rules\Captcha;

class RegistrationTest extends TestCase {

    public test_user_registration()
    {
        $this->mock(Captcha::class, function ($mock) {
            $mock->shouldReceive('passes')->andReturn(true);
        });

        $response = $this->post(route('tenant.register'), [
            'g-recaptcha-response' => 1,
            'email' => '[e-mail]',
            'password' => 'secret',
        ]);

        $this->assertEquals(1, User::all()->count());
     }
} 

同时包含FormRequest和Controller文件

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use App\Rules\Captcha;

class NewUserRequest extends FormRequest {

    public function rules()
    {
        return [
            'name' => ['required', new Captcha]
        ];
    }
}

...

public function postRegister(NewUserRequest $request) {

...

编辑II:似乎是Laravel本身的错误；

EDIT II: seems like a bug in Laravel itself;

推荐答案

必须通过Laravels服务容器实例化该类，以便对其进行模拟.最好的方法(在这种情况下)是将new Captcha更改为app(Captcha::class):

The class must be instantiated through Laravels service container in order for it to be mocked. The best way to accomplish this (in this situation) is to simply change new Captcha to app(Captcha::class):

命名空间App \ Http \ Requests;

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use App\Rules\Captcha;

class NewUserRequest extends FormRequest {

    public function rules()
    {
        return [
            'name' => ['required', app(Captcha::class)]
        ];
    }
}

我建议您不要告诉规则本身根据环境来更改其行为，因为当您试图弄清验证码在开发环境中什么都不做的时候，这可能会引起混乱.生产失败.

I would advise against telling the rule itself to change its behaviors based on environments as that could result in a bit of confusion down the line when you are trying to figure out why the captcha doesn't do anything in dev environments but is failing in production.
