Basic Testing With Behat

Prerequisites

  • PHP 5+
  • Composer command

Note: our local-development environment already satisfies all prerequisites.

Install

Install behat and it's dependencies

composer require drupal/drupal-extension

Configure

behat.yml

Create a behat.yml file in your project root folder, please ensure to set base_url, files_path and drupal_root to match your project parameters

default:
  suites:
    default:
      contexts:
        - FeatureContext
        - Drupal\DrupalExtension\Context\DrupalContext
        - Drupal\DrupalExtension\Context\MinkContext
        - Drupal\DrupalExtension\Context\MessageContext
        - Drupal\DrupalExtension\Context\DrushContext
  extensions:
    Behat\MinkExtension:
      goutte: ~
      base_url: http://www.coesia.hart.sparkfabrik.loc/
      selenium2:
        wd_host: "http://phantomjs:8910/wd/hub"
      files_path: '/var/www/html/features'
    Drupal\DrupalExtension:
      blackbox: ~
      api_driver: 'drupal'
      drush_driver: 'drush'
      drupal:
        drupal_root: '/var/www/html/web'
      drush:
        root: '/var/www/html/web'

You can also add region mapping by adding (for example) the following to beaht.yml file:

      region_map:
        search bar: '.search-bar'
        corporate_left: '.site-header .corporate .large-6:first-child'
        corporate_right: '.site-header .corporate .large-6:last-child'
        corporate_left_mobile: '.site-header .mobile_inner-wr .mobile-corporate'
        corporate_right_mobile: '.site-header .mobile_inner-wr .mobile-corporate'
        header_menu_mobile: '.site-header .mobile_inner-wr'
        header_menu: '.site-header .main-menu-wr > columns'
        header: '.site-header'
        page_header: '.page-header-region'
        highlighted: '.highlighted'
        content_before: '.content-before_wr'
        sidebar_left: '.sidebar-left'
        footer: '.site-footer .columns:not(.large-6)'

Phantomjs

Add a phantomjs container to your docker-compose.yml

phantomjs:
  image: cmfatih/phantomjs:latest
  entrypoint: phantomjs
  command: --webdriver=8910

Create your first test feature

Create a folder named feature in the project root folder

mkdir ./feature

Add a feature with basic testing: create a .feature in the feature folder like this:

[nano|vi|whatever] feature/example/basic_test.feature

with the following content:

Feature: Example Test Project Pages

  As an anonymous user
  I want to test page responses and look for errors

  Scenario: Test Project Pages
    Given I am an anonymous user
    And I am on the homepage
    Then I should get a 200 HTTP response
    And  I should see the text "Select your country"

    Given I am an anonymous user
    When I visit "italy/it"
    Then I should get a 200 HTTP response
    And  I should see the text "Page under construction"

  Scenario: Test if fields  have been removed
    Given I log in as admin
    When I visit "italy/it/admin/reports/fields"
    Then I should get a 200 HTTP response
    And  I should not see the text "field_singlepg_learn_video_coll"
    And  I should not see the text "field_communiication_campaigns"
    And  I should not see the text "field_communication_brand_header"

Run tests

When using our docker-based local dev environment, behat must be run in the container. We provided a shortcut script that can be invoked by the host OS.

Run your tests by issuing

bin/e bin/behat

If you want to see which are the predefined steps available in the drupal extension, run

bin/e bin/behat -dl
