Can't install the dependencies on a Laravel 5.6 project

[programarivm]

When pulling the dependencies through Composer:

composer require behat/behat behat/mink behat/mink-extension laracasts/behat-laravel-extension symfony/dependency-injection:"3.*" --dev

I got the output:

Using version ^3.4 for behat/behat
Using version ^1.7 for behat/mink
Using version ^2.3 for behat/mink-extension
Using version ^1.1 for laracasts/behat-laravel-extension

The following workaround seems to do the trick:

composer require behat/behat behat/mink behat/mink-extension laracasts/behat-laravel-extension symfony/dependency-injection:"4.*" --dev

However I feel as if jumping into the unknown as described at Behat/Behat#1108. Can laracasts/Behat-Laravel-Extension be used with Laravel 5.6?

At the moment, I think you'd need to use these changes (or something similar) to get L5.6 deps working right with Behat. I have been doing so for a couple weeks now, and it seems fine.

However, until Behat/Behat#1163 is merged, you would also need to use the flaxandteal/Behat branch referenced there for Behat.

I haven't PR'd on this repo yet, pending Behat/Behat#1163 (as it's only useful as a pair), but they are not actually interdepedent, so I can set up a PR here and get the ball rolling?

Thank you @philtweir! I finally managed to set up Behat for L5.6 without the extension. My Behat tests can interact with the database using Capsule as explained here.

Btw, here is a basic example on how to use Behat for L5.6 with Capsule :)

<?php

use App\Utils\SingleManning;
use Dotenv\Dotenv;
use Illuminate\Database\Capsule\Manager as Capsule;

abstract class AbstractRotaContext
{
    protected $capsule;

    protected $singleManning;

    protected $rotaId;

    public function __construct($rotaId)
    {
        $dotenv = new Dotenv(__DIR__.'/../../');
        $dotenv->load();

        $this->capsule = new Capsule;

        $this->capsule->addConnection([
            'driver'    => 'mysql',
            'host'      => getenv('DB_HOST'),
            'database'  => getenv('DB_DATABASE'),
            'username'  => getenv('DB_USERNAME'),
            'password'  => getenv('DB_PASSWORD'),
        ]);

        $this->capsule->setAsGlobal();
        $this->capsule->bootEloquent();

        $this->singleManning = new SingleManning($this->capsule);

        $this->rotaId = $rotaId;
    }

    protected function works($firstName, $start)
    {
        $pdo = Capsule::connection()->getPdo();

        $stm = $pdo->prepare(
            'SELECT * FROM shifts AS sh
                JOIN staff as st ON sh.staff_id = st.id
                WHERE DATE(sh.start_time) = :start
                AND st.first_name = :firstName');

        $stm->execute(
            [
                ':start' => $start,
                ':firstName' => $firstName
            ]
        );

        return $stm->rowCount() === 1;
    }
    ...
}

Cool! That's a really nice option, especially as I can see it often being a better match than the spinning up all the non-DB utils - may take a look at the approach in general for some of our needs. Just as an update for those who have slightly more specific reqs (e.g. our team's API testing plugin), #81 should address the underlying bug.
