Collision PHPUnit Listener With Laravel

Collision is an error reporting tool for PHP command line applications. It ships as a dev dependency for Laravel starting back in Laravel 5.6, but I recently noticed the package’s author mention the PHPUnit adapter:

Hey friend. You may want to take a look at Collision's PHPUnit adapter. https://t.co/8phZ47PH3W pic.twitter.com/y4gDIlctK3

While collision ships with Laravel, you need to configure the listener if you want to use it with PHPUnit. I thought I’d quickly demonstrate setting it up with Laravel.

Here’s the default PHPUnit experience when you have an exception during a test. You might notice that the first place you want to look is the top of the exception stack, so you have to scroll up to see it:

To get a much better experience, add the Collision printer class to your Laravel project’s phpunit.xml file:

<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="./vendor/phpunit/phpunit/phpunit.xsd"
         bootstrap="vendor/autoload.php"
         colors="true"
         printerClass="NunoMaduro\Collision\Adapters\Phpunit\Printer"
>
<!-- ... -->
</phpunit>

Now you get a nice clean view of where the exception occurred after the full stack trace:

Boom! Collision provides a much better experience while running PHPUnit tests via the command line!
