Running Behat in PHPUnit to calculate code coverage

BehatTest.php

<?php

use Symfony\Component\Console\Input\ArrayInput;
use Symfony\Component\Console\Output\ConsoleOutput;
use Symfony\Bundle\FrameworkBundle\Console\Application;
use Behat\BehatBundle\Command\BehatCommand;

class BehatTest extends KernelAwareTest
{
    /**
     * @group behat
     */
    public function testThatBehatScenariosMeetAcceptanceCriteria()
    {
        try {
            $input = new ArrayInput(array('behat', '-e' => 'test', '--format' => 'progress'));
            $output = new ConsoleOutput();
            $application = new Application($this->kernel);
            $command = new BehatCommand('behat');
            $command->setApplication($application);
            $result = $command->run($input, $output);

            $this->assertEquals(0, $result);
        } catch (\Exception $exception) {
            $this->fail($exception->getMessage());
        }
    }
}

@khepin yes but here's the original: https://gist.github.com/1319290

Updated for sf2.1 https://gist.github.com/4594469

I guess that is meant to be used when there are no http requests (mink steps) Behat/Behat#92
