Add support for testing languages

[pfrenssen]

It would be nice if we could add support for testing languages. I'm using Behat for an internal Drupal platform that is used in the European Commission, and we are currently supporting 24 languages :)

This pull requests adds a step definition for enabling additional languages in tests:

Given the following languages are available:
  | languages |
  | en        |
  | fr        |
  | de        |

This is currently depending on my fork of Drupal Driver that adds the respective functionality for creating and deleting languages. The sister pull request for Drupal Driver is here: jhedstrom/DrupalDriver#45

In case this is accepted we would need to revert commit 55f03a4 before merging this in. That commit points the Drupal Driver dependency to my own fork.

Big 👍 for this one!

One of the Travis test bots stalled, but it doesn't seem to be possible to trigger a retest. I'll have to make a new commit.

[jhedstrom]

I restarted the test.

This can be switched back now as I've merged jhedstrom/DrupalDriver#45

This looks great. Small change mentioned above, and then it should be good to go!

[jhedstrom]

Awesome, thanks!

Sorry to comment on an old thread but it was not clear how to test for translations when in fact the DrupalExtension itself has hardcoded English strings:

          addDefaultsIfNotSet()->
          children()->
            scalarNode('log_in')->
              defaultValue('Log in')->
            end()->
            scalarNode('log_out')->
              defaultValue('Log out')->
            end()->
            scalarNode('password_field')->
              defaultValue('Password')->
            end()->
            scalarNode('username_field')->
              defaultValue('Username')->
            end()->
          end()->

  Scenario: Administrator role exists
    Given I am logged in as an "administrator"

This scenario may result in an error if you have another default language as it tries to login using the English strings:
Form field with id|name|label|value|placeholder "Username" not found. (Behat\Mink\Exception\ElementNotFoundException)

You can override the strings in your behat.yml configuration.

    Drupal\DrupalExtension:
        text:
            username_field: "Gebruikersnaam"
            password_field: "Wachtwoord"
            log_in: "Inloggen"
            log_out: "Uitloggen"
