Symfony 3.1 + PhpUnit：未报告控制器异常

Question

I use Symfony 3.1.9 and PhpUnit 5.6.5.

Whenever an exception occurs in a controller, it is handled by symfony and the stack trace is displayed in views.

How can I fix this and make phpunit output the exception ?

My phpunit config :

<?xml version="1.0" encoding="UTF-8"?>

<!-- https://phpunit.de/manual/current/en/appendixes.configuration.html -->
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/4.8/phpunit.xsd"
         backupGlobals="false"
         colors="true"
         bootstrap="app/autoload.php"
>
    <php>
        <ini name="error_reporting" value="-1" />
        <server name="KERNEL_DIR" value="app/" />
    </php>

    <testsuites>
        <testsuite name="Project Test Suite">
            <directory>tests</directory>
        </testsuite>
    </testsuites>

    <filter>
        <whitelist>
            <directory>src</directory>
            <exclude>
                <directory>src/*Bundle/Resources</directory>
                <directory>src/*/*Bundle/Resources</directory>
                <directory>src/*/Bundle/*Bundle/Resources</directory>
            </exclude>
        </whitelist>
    </filter>
</phpunit>

Edit : It seems related to how twig renders exceptions in test and dev the same way. As stated in https://symfony.com/doc/current/configuration/environments.html :

Regardless of the environment, a Symfony application can be run with debug mode set to true or false. This affects many things in the application, such as displaying stacktraces on error pages or if cache files are dynamically rebuilt on each request. Though not a requirement, debug mode is generally set to true for the dev and test environments and false for the prod environment.

Now how can we set kernel.debug parameter in test ?

Answer 1

For now it seems the best option is to add a line in config_test.yml to disable twig exception handler

twig:
  exception_controller: false
