Take screenshot after a step failed in Behat/Mink using Selenium WebDriver

takeScreenshotAfterFailedStep.php

<?php

class FeatureContext extends MinkContext {

	/**
	 * Take screenshot when step fails. Works only with Selenium2Driver.
	 * Screenshot is saved at [Date]/[Feature]/[Scenario]/[Step].jpg
	 *
	 * @AfterStep @javascript
	 */
	public function takeScreenshotAfterFailedStep(Behat\Behat\Event\StepEvent $event) {
		if ($event->getResult() === Behat\Behat\Event\StepEvent::FAILED) {
			$driver = $this->getSession()->getDriver();
			if ($driver instanceof Behat\Mink\Driver\Selenium2Driver) {
				$step = $event->getStep();
				$path = array(
					'date' => date("Ymd-Hi"),
					'feature' => $step->getParent()->getFeature()->getTitle(),
					'scenario' => $step->getParent()->getTitle(),
					'step' => $step->getType() . ' ' . $step->getText()
				);
				$path = preg_replace('/[^\-\.\w]/', '_', $path);
				$filename = '/tmp/behat/' .  implode('/', $path) . '.jpg';

				// Create directories if needed
				if (!@is_dir(dirname($filename))) {
					@mkdir(dirname($filename), 0775, TRUE);
				}

				file_put_contents($filename, $driver->getScreenshot());
			}
		}
	}
}

Does not seem to work anymore. Adding the function to the FeatureContext didnt hook it up with an afterStep. Has anything changed recently? Is this still working for you?

@bizmate still works for me however the screenshots are saved as png not jpg.
