How to configure behat tests properly with behat 3 and drupalextension 3.1

[mradcliffe]

I must be missing something obvious as I have not been able to find any information regarding not recognizing any step definitions when running behat despite seeing all of DrupalExtension's step definitions with behat -dl. :(

Is there somewhere else that I can look? Some configuration option I am missing that's not in the docs? Some behat/mink/whatever library I am missing? Missing namespaces? Autoload problems? I have no idea what to do next other than re-write everything myself which seems like the worst option.

I've tried running this within a vagrant virtual machine or outside of one, but I get the same result with behat:

./vendor/bin/behat
Feature: Anonymous Users

  Scenario: User visits front page     # features/platform/anonymous.feature:3
    Given I am not logged in
    When I visit "/"
    Then I should see a "name" element
    And I should see a "pass" element

1 scenario (1 undefined)
4 steps (4 undefined)
0m0.09s (12.32Mb)

--- FeatureContext has missing steps. Define them with these snippets:

    /**
     * @Given I am not logged in
     */
    public function iAmNotLoggedIn()
    {
        throw new PendingException();
    }

    /**
     * @When I visit :arg1
     */
    public function iVisit($arg1)
    {
        throw new PendingException();
    }

    /**
     * @Then I should see a :arg1 element
     */
    public function iShouldSeeAElement($arg1)
    {
        throw new PendingException();
    }

./vendor/bin/behat -dl | grep "I am not logged in"
default | Given I am not logged in

behat.yml

default:
  suites:
    default:
      contexts:
        - FeatureContext

      filters:
        tags: "@blackbox"

Feature: Anonymous Users

  Scenario: User visits front page
    Given I am not logged in
    When I visit "/"

features/bootstrap/FeatureContext.php

use Behat\Behat\Context\SnippetAcceptingContext;
use Behat\Gherkin\Node\PyStringNode;
use Behat\Gherkin\Node\TableNode;
use Drupal\DrupalExtension\Context\RawDrupalContext;

class FeatureContext extends RawDrupalContext implements 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() {
  }
}

My test directory structure:

behat.yml
composer.json
composer.lock
features/bootstrap/FeatureContext.php
features/platform/anonymous.feature
vendor

composer.json:

{
    "require": {
        "behat/mink": "~1.0",
        "behat/mink-goutte-driver": "~1.0",
        "behat/mink-selenium2-driver": "~1.1",
        "behat/mink-extension": "~2.0",
        "drupal/drupal-extension": "~3.1",
        "jcalderonzumba/mink-phantomjs-driver": "~0.3.1"
    }
}

Extending RawDrupalContext causes none of the step definitions to be found, but every other project/example i've seen extends it. So confusing.

But now with the same thing, I cannot get the Mink session to instantiate. It just complains with a very unintuitive error message: Mink instance has not been set on Mink context class. Have you enabled the Mink Extension? Why, yes, I do have MinkExtension in my behat.yml file.

I tried changing my behat.yml instead of what I had above (for the relevant section):

Behat\MinkExtension:
  sessions:
    default:
      goutte: ~

but mink still complains about not having an Mink instance.

I still must be missing something pretty big in the instructions or documentation about Behat/MinkExtension/DrupalExtension. Every blog post seems to skip over actually instantiating a Mink session or assumes that it just works.

I found a couple of issues with what I had done:

• The composer dependencies seem to be the root of the issue, and I started from scratch with Composer on a linux box (and then replicating it back on my mac):
  • I set minimum-stability to stable
  • I used ^3.1 instead of ~3.1 for drupal\drupal-extension
  • I used ^0.1.3 instead of ~0.3.1 for jcalderonzumba/behat-phantomjs-extension
• Finally after I got some progress I found that the @blackbox tag under filters caused my feature to disappear until I added that tag above the feature. This was not explained anywhere that I could find. I finally understood what to do because I got the PhantomJS bit working which had some examples with @javascript boilerplate at the top of the feature file.
