  8. Who am I? Seth Cohn • @sethcohn at drupal.org, twitter, and elsewhere • Almost 9 years of Drupal • Worked as independent, part of development companies,non-profits, and more.. • Elected in NH in 2010 as State Representative, prime sponsored the first Open Source/Open Data bill passed into law in USA

  9. Who should use this? • Who is the target of this talk? • Developers who want to be clear on what they are being asked to build • Project Managers who want to be clear on what they are requesting be built • Anyone using Agile methods or who wants to… • End Users working to get new useful features built • Anyone wanting to drive focused development

  10. Behat is? What is Behat? “Behat is a tool that makes behavior driven development (BDD) possible.” http://docs.behat.org first line of the quick intro So let’s ask what BDD is?

  11. behavior driven development (BDD)? What is that? Coined by Dan North, http://dannorth.net who was teaching Test Driven Development, and asking questions like: • Where to start in the process? • What to test and what not to test? • How much to test in one go? • What to call the tests? • How to understand why a test fails?

  19. behavior driven development (BDD)? BDD rethinks testing: • should be written in order of business value • should use the standard agile framework of a User story: • "As a [role] I want [feature] so that [benefit]” • should be written with Acceptance criteriain terms of scenarios and implemented as classes: • Given [initial context], when [event occurs], then [ensure some outcomes]

  39. Nitty Gritty details Or how the heck does this work? • Sites we don’t control (blackbox) – Wikipedia demo example • Sites we do control (but still blackbox) – local Drupal 8 install demo example • Whitebox – not demoing today

  40. Why should Drupal embrace BDD? • Benefits to community • Better testing of all of the code, especially code you didn’t author yourself • Benefits to developer • Write simpler tests and get cleaner tests • improve your code, and your overall site especially with help of non-tech folks • Benefits to end user and site owners • PROFIT! Business focus = productive changes! • Better communication of needs and goals

  41. Which behat‘module’ to use? Modules at Drupal.org: • behat: It allows you to write feature tests for a Drupal site using SimpleTest API functions and assertions in step definitions. • behat_testing: Integrates behat with drush and adds own step definitions for Drupal • drupalextension: Provides a DrupalExtension with Drupal step definitions. • doobie: used to test Drupal.orgsite w/ behat.

  42. Drupal.org • Why does Drupal.orgnow use Behat? • Developers don’t get access to the main Drupal boxes… • Breaking Drupal.org is a bad thing! • Updating from D5 to D6 to D7 (to D8…)? Don’t want to lose features, functionality, etc…
