symfony - 如何在单元测试我的 Symfony2 包时显示 PHP 错误？

Question

目前，在为我的 Symfony2 包编写单元测试时，我明确设置了 ini_set('display_errors', 1) 以确保我看到在编写单元测试时所犯的任何错误。这对于 fatal error 特别有用，例如由于方法名称中的拼写错误而导致的错误。

示例:

# src/Foo/BarBundle/Tests/Security/RoutePermissionCheckerTest.php

namespace Foo\BarBundle\Tests\Security;

use Symfony\Bundle\FrameworkBundle\Tests\TestCase;

class RoutePermissionCheckerTest extends TestCase
{
    public function testIndex()
    {
        ini_set('display_errors', 1);
        $this->nonExistentMethod();
    }
}

输出:

Configuration read from /Users/maurits_dekkers/Sites/hobby/symfony/saas-seed/app/phpunit.xml.dist
...
Fatal error: Call to undefined method Bb\UserBundle\Tests\Security\RoutePermissionCheckerTest::nonExistentMethod() in /Users/maurits_dekkers/Sites/hobby/symfony/saas-seed/src/Bb/UserBundle/Tests/Security/RoutePermissionCheckerTest.php on line 18

但是，必须有更好的方法通过配置设置。我尝试在 config_test.yml 中添加额外的 Monolog 设置:

# app/config/config_test.yml
monolog:
    handlers:
        console:
            type:   console
            bubble: false
            level: info

但这不会导致我的单元测试期间报告 PHP 错误。单元测试只是停止运行。

是否有一种简单的方法来配置我的 Symfony2 项目以在单元测试期间始终报告错误？

您可能需要在 PHPUnit 配置文件 (app/config/phpunit.xml) 中将以下参数设置为 true:

• convertErrorsToException
• convertNoticesToExceptions
• convertNoticesToExceptions
