How to show PHP errors when unit testing my Symfony2 bundle? - symfony

Question

Currently, when writing a unit test for my Symfony2 bundle, I explicitly set ini_set('display_errors', 1) to make sure I see any errors I made in writing my unit test. This is particularly helpful for fatal errors, such as those resulting from typos in method names.
Example:
# 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();
}
}
Output:
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

However, there must be a better way by means of a configuration setting. I've tried adding an extra Monolog setting to my config_test.yml:
# app/config/config_test.yml
monolog:
handlers:
console:
type: console
bubble: false
level: info
but that does not result in PHP errors being reported during my unit test. The unit test simply stops running.
Is there an easy way to configure my Symfony2 project to always report errors during a unit test?

Answer 1

You might want to set the following parameters to true in your PHPUnit configuration file (app/config/phpunit.xml):
convertErrorsToException
convertNoticesToExceptions
convertNoticesToExceptions
