Behat 3 with Laravel 5: acceptance test passes but it should not - php

Question

I'm doing my firsts acceptance tests for a Laravel 5 application using Behat 3 and Mink.
The application runs under a Homestead VM.
The test is straightforward and is located in the features/example.feature file. This is the test:
Feature: Sample
In order to learn Behat
As a programmer
I need a simple url testing
Scenario: Registration
Given I am not logged in
When I go to the registration form
Then I will be automatically logged in
The FeatureContext.php has this class:
<?php
use Behat\Behat\Tester\Exception\PendingException;
use Behat\Behat\Context\Context;
use Behat\Behat\Context\SnippetAcceptingContext;
use Behat\Gherkin\Node\PyStringNode;
use Behat\Gherkin\Node\TableNode;
use Behat\MinkExtension\Context\MinkContext;
/**
* Defines application features from the specific context.
*/
class FeatureContext extends MinkContext implements Context, SnippetAcceptingContext
{
/**
* Initializes context.
*
* Every scenario gets its own context instance.
* You can also pass arbitrary arguments to the
* context constructor through behat.yml.
*/
public function __construct()
{
}
/**
* #Given I am not logged in
*/
public function iAmNotLoggedIn()
{
Auth::guest();
}
/**
* #When I go to the registration form
*/
public function iGoToTheRegistrationForm()
{
$this->visit(url('my/url'));
}
/**
* #Then I will be automatically logged in
*/
public function iWillBeAutomaticallyLoggedIn()
{
Auth::check();
}
}
Then, when I run behat from the command line, I expect the test to fail because there is no my/url route (the routes.php file only has a route for /).
However, the test returns green, and this is what I see:
Feature: Sample
In order to learn Behat
As a programmer
I need a simple url testing
Scenario: Registration # features/example.feature:7
Given I am not logged in # FeatureContext::iAmNotLoggedIn()
When I go to the registration form # FeatureContext::iGoToTheRegistrationForm()
Then I will be automatically logged in # FeatureContext::iWillBeAutomaticallyLoggedIn()
1 scenario (1 passed)
3 steps (3 passed)

Of course, I'm using the laracasts/behat-laravel-extension package and this is the content of the beat.yml file:
default:
extensions:
Laracasts\Behat: ~
Behat\MinkExtension:
default_session: laravel
laravel: ~
Thank you very much for any help!

Answer 1

Behat is very simple. It treats a step as failed if an exception is thrown while executing it. It treats a step as successful otherwise.
As far as I can tell from the docs, Auth::check() does not throw an exception if user is not authenticated. It simply returns a boolean value.
Your step should be rather implemented more like the following:
/**
* #Then I will be automatically logged in
*/
public function iWillBeAutomaticallyLoggedIn()
{
if (!Auth::check()) {
throw new \LogicException('User was not logged in');
}
}
Your "I go to the registration form" step succeeds since you don't really verify if the page you visited is the one you expected to load. Again, you should throw an exception if a page you visited is not the right one.
