Behat 3: Taking screenshots after failed steps

[bentcoder]

Code below works fine for Behat 2 but it doesn't for Behat 3. Does anyone know how to implement it in Behat 3?

_Behat 3 error:_

PHP Fatal error:  Call to undefined method Behat\Behat\Hook\Scope\AfterStepScope::getResult() in behat-three/features/bootstrap/Site/MainBundle/Features/Context/FeatureContext.php on line 65

Line 65 is : if (4 === $event->getResult()) {

_Behat 2 working example_

    public function takeScreenshotAfterFailedStep($event)
    {

            $driver = $this->getSession()->getDriver();

            if (! ($driver instanceof Selenium2Driver)) {
                throw new UnsupportedDriverActionException(
                    'Taking screen-shots is not supported by %s, use Selenium2Driver instead.',
                    $driver
                );

                return;
            }

            if (! is_dir($this->screenShotPath)) {
                mkdir($this->screenShotPath, 0777, true);
            }

            $filename = sprintf(
                '%s_%s_%s.%s',
                $this->getMinkParameter('browser_name'),
                date('Ymd') . '-' . date('His'),
                uniqid('', true),
                'png'
            );

            file_put_contents($this->screenShotPath . '/' . $filename, $driver->getScreenshot());
        }
    }
}

        }
    }

        $filePath = $this->getContainer()->get('kernel')->getRootdir() . '/../web/tmp/';

        $this->saveScreenshot($fileName, $filePath);
        print 'Screenshot at: ' . $baseUrl . 'tmp/' . $fileName;
    }

Something like that works

[bentcoder]

That worked well. Thanks.

Not working for me undefined method getContainer(), which lib did you use? (behat 3)

[bentcoder]

@narozhniyy If you can wait a bit, I'll give you full example however while waiting, do research on how to use container in FeatureContext files. There are many examples so you might solve your problem yourself.

[narozhniyy]

@bentcoder it's will be great, thanks

[narozhniyy]

@bentcoder did you forget about me?

[bentcoder]

@narozhniyy No I didn't! There seem to be a problem with the library I think because what was working before doesn't want to work anymore hence reason I left a message here #764 but no one got back to me yet. Keep an eye on that issue. Let's wait what they say.

[bentcoder]

OK work now!
