Adds the ability to test Symfony commands

[mikaelrandy]

With this commit, its become possible to easily test commands

Exemple :

<?php

namespace My\Bundle\FoobarBundle\Tests\Units\Command;

use atoum\AtoumBundle\Test\Units as AtoumBundle;
use mageekguy\atoum;
use Symfony\Bundle\FrameworkBundle\Console\Application;
use Symfony\Component\Console\Tester\CommandTester;

// Assuming that this command will display "Success" if succes, and returns a boolean
use My\Bundle\FoobarBundle\Tests\Units\Command\FoobarCommand as Base;

class FoobarCommand extends AtoumBundle\CommandTestCase
{
    public function testExecute()
    {
        $this
            ->given(
                $command = new Base()
            )
            ->if($commandTester = $this->createCommandTester($command))
            ->then
                ->boolean($commandTester->execute())
                    ->isTrue()
                ->string($commandTester->getDisplay())
                    ->contains("Success")
        ;
    }
}

If you could add your example in the readme, it would be awesome!

There is something missing on this PR ? What is the next step ?

[jubianchi]

If everything is ok for everyone, I propose to merge and tag a release for the bundle.

I can handle it.

[mikaelrandy]

Great !

For information, i can't do anything on the bundle ;)

[FlorianLB]

I will do it. I will review all remaining PR and tag a new release.

👍🏻 @FlorianLB

Is there a BC break here ?

Next version will be 1.2.0 or 2.0.0 ?

[mikaelrandy]

There is no regression in the interface, just some code moved to one level up in class hierarchy.
