Doing something with the exception message after a failing behat scenario using @afterstep.

DebugContext.php

<?php

namespace Context;

use Behat\Behat\Hook\Scope\AfterStepScope;
use Behat\Testwork\Tester\Result\ExceptionResult;

class DebugContext extends BaseContext
{
    /**
     * @AfterStep
     */
    public function doSomethingOnFailed(AfterStepScope $event)
    {
        // not an error
        if (!$event->getTestResult() instanceof ExceptionResult) {
            return;
        }

        $step = $event->getStep();
        print sprintf("Step that failed : %s\n", $step->getText());
        
        $exception = $event->getTestResult()->getException();
        print sprintf("Exception was : %s\n", $exception->getMessage());
    }
    
    // ...
}

FYI I have not actually tested this, if it does not work, try and look at Behat API.

Hey Tentacode - 'getException' doesn't seem to be an option in v3 (I only get getResultCode and isPassed as options here). Any idea where it went, I can't find any reference to it after v2.5 of the Behat api docs.
