如何在Laravel 5中测试自定义验证规则?

I created a custom validation rule in Laravel, extending it in the register() method of a service provider, and I'd like to test it, but don't know how.

I took a look at Laravel framework's validation tests, but I couldn't understand the purpose of the getTranslator() and getRealTranslator() methods.

Could someone give me a hint on how to test Laravel's custom validation rules?

EDIT

That's what I did:

Created a ValidatorServiceProvider as follows:

<?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()
    {
    }
}

Also added it to the providers array and issued composer dump-autoload -o.

Added the following to 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;
    }

}

Running PHPUnit gives me the following:

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

What I'm doing wrong?

Thanks!

    You need to understand a bit more the Container or IoC and how the Validator is registered there.

    Laravel registers an instance of Illuminate\Validation\Factory as validator. So if you check the \Illuminate\Support\Facades\Validator, you find that it resolves to the Factory. When you extend the validator, you are in fact adding an extension in the Factory. Now, calling Validator::make() calls the Factory which has the extensions and it creates the Validator with the extensions, while instantiating a new Illuminate\Validation\Validator won't be able to resolve the extentions from the Factory.

    You should not instantiate a new Validator, but use app('validator')->make().

    Take it:

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