Test Driven Drupal: The Book

Having given talks and workshops, been a guest on podcasts and written blog posts about automated testing in Drupal, I’m currently in the planning phase of a book and potentially some accompanying screencasts about it, focussing on Drupal 8.

I’m still thinking about what use-cases to cover and examples to include, but here are some of the things I’m considering:

  • What things to test, and what not to test
  • The different types of available tests, and when to use each
  • How to write testable code
  • What happens when I run a test?
  • How to run tests in the Drupal UI
  • How to run tests with the run-tests.sh script
  • How to install, configure and run tests with PHPUnit in Drupal 8
  • Viewing HTML from run tests
  • How to write your first test
  • Debugging tests
  • How to organise your test files
  • Selecting the right base class and using test traits
  • Writing your own base test classes, traits and assertions
  • Managing dependencies for your tests (fields, configuration)
  • Creating users, checking access with roles and permissions
  • Creating pages and blocks with Views and testing the output
  • Creating pages with routes and controllers and testing the output
  • Testing custom plugins
  • Testing queuing items and processing queues
  • Testing sending emails
  • Testing custom Twig filters and functions
  • Running tests as part of your continuous integration pipeline

I’ll most likely be publishing it via Leanpub, and will be sending free chapters, early-bird discounts and links to screencasts and blog posts as I write the book to subscribers of the mailing list.

If you have questions or would like to suggest something for me to include in the book, please contact me.
