Question

我在Laravel中创建了一个自定义验证规则，在服务提供商的register()方法中扩展它，我想测试它，但不知道如何。

我看了Laravel framework's validation tests，但我无法理解getTranslator()和getRealTranslator()方法的目的。

有人可以给我一些关于如何测试Laravel自定义验证规则的提示吗？

修改

这就是我所做的：

按如下方式创建ValidatorServiceProvider：

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class ValidatorServiceProvider extends ServiceProvider {

    /**
    * Bootstrap the application services.
    *
    * @return void
    */
    public function boot()
    {
        $this->app['validator']->extend('greater_than', function($attr, $val, $params)
        {
            return false;
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
    }
}

还将其添加到providers数组并发布composer dump-autoload -o。

将以下内容添加到tests\CustomValidationRulesTest.php：

<?php

use Mockery as m;
use Illuminate\Validation\Validator;

class CustomValidationRulesTest extends TestCase {

    public function tearDown()
    {
        m::close();
    }

    public function testValidateGreaterThan()
    {
        $trans = $this->getTranslator();

        $rules = [
            'field2' => 'greater_than:field1'
        ];

        $data = [
            'field1' => 1,
            'field2' => 2
        ];

        $v = new Validator($trans, $data, $rules);
        $this->assertTrue($v->passes());
    }

    protected function getTranslator()
    {
        return m::mock('Symfony\Component\Translation\TranslatorInterface');
    }

    protected function getRealTranslator()
    {
        $trans = new Symfony\Component\Translation\Translator('en', new Symfony\Component\Translation\MessageSelector);
        $trans->addLoader('array', new Symfony\Component\Translation\Loader\ArrayLoader);
        return $trans;
    }

}

运行PHPUnit给出了以下内容：

PHPUnit 4.6.6 by Sebastian Bergmann and contributors.

Configuration read from /home/ubuntu/workspace/phpunit.xml

E.

Time: 248 ms, Memory: 14.75Mb

There was 1 error:

1) CustomValidationRulesTest::testValidateGreaterThan
BadMethodCallException: Method [validateGreaterThan] does not exist.

/home/ubuntu/workspace/vendor/laravel/framework/src/Illuminate/Validation/Validator.php:2615
/home/ubuntu/workspace/vendor/laravel/framework/src/Illuminate/Validation/Validator.php:372
/home/ubuntu/workspace/vendor/laravel/framework/src/Illuminate/Validation/Validator.php:372
/home/ubuntu/workspace/vendor/laravel/framework/src/Illuminate/Validation/Validator.php:325
/home/ubuntu/workspace/tests/CustomValidationRulesTest.php:27

我做错了什么？

谢谢！

Answer 1

您需要了解Container或IoC以及Validator在那里注册的方式。

Laravel将Illuminate\Validation\Factory的实例注册为validator。因此，如果您检查\Illuminate\Support\Facades\Validator，则会发现它已解析为Factory。扩展验证器时，实际上是在Factory中添加了扩展名。现在，调用Validator::make()会调用包含扩展名的Factory，并创建包含扩展名的Validator，而实例化新的Illuminate\Validation\Validator则无法解析来自Factory的扩展。

您不应该实例化新的Validator，而是使用app('validator')->make()。

接受它：

protected function getRealTranslator()
    {
        $loader = new \Illuminate\Translation\ArrayLoader;
        $translator = new \Illuminate\Translation\Translator($loader, 'ja');
        return $translator;
    }

如何在Laravel 5中测试自定义验证规则？
