[5.7] Mock console output while testing to help making assertions

[themsaid]

This makes it easier to test interactive artisan commands and also do assertions on the console output.

public function testBasicTest()
{

    $this->artisan('package:install')
        ->expectsQuestion('Please provide a token', 'tokenSecret')
        ->expectsOutput('Token is valid')
        ->expectsQuestion('Please select a release', 'v2.0')
        ->expectsQuestion('Are you sure you want to install v2.0?', 'yes')
        ->expectsOutput('Installing...')
        ->assertStatus(0);
}

For a console command like this:

public function handle()
{
    $token = $this->secret('Please provide a token');

    if(...){
        $this->info('Token is valid');
    }

    $release = $this->choice('Please select a release', ['v1.0', 'v2.0']);

    if ($this->confirm('Are you sure you want to install '.release.'?')) {
        $this->info('Installing...');
    }
}

Is this the result of one of the items in the Twitter list? Cool stuff!

@deleugpn yup :)

Not sure the test is working correctly with confirm() method. I'll confirm that and submit test for that
