Add Automated Testing to Your Project in an Afternoon Michael Sherron, Technical Architect

About Me →Michael Sherron →Drupalist, 6 years →Technical Architect, Acquia →‘Raised’ in small Drupal Shops

Testing protects you from fail →Most people know the benefits of Test automation →Small shops often overworked →Some clients won’t pay for it

What is Wraith? →Visual Regression Testing tool →Automates comparing screenshots of pages across different environments →If screenshots are different, an error is triggered →Provides nice gallery to view screenshots →Easy to implement

Isn’t this for theme testing? What can Wraith do? →Can crawl an entire site out of the box →Can test responsively →Will report an error if:  elements are missing or broken on the page  WSOD  Default red error text is displayed

Wraith != Behat →This is an MVP testing solution. →Great for simple sites with mostly anonymous traffic. →You really should learn Behat or similar. →Doesn’t handle:  Authenticated users  Transaction-based tests (user signup, cart checkouts, etc)

… But if you have Behat, Wraith is still great! →Visual Regression testing will catch things Behat can’t. →Page elements moved/changed unexpectedly

Requirements →Can be run locally or on a remote server. →Root/Sudo access. →At least one production and one test environment. →Familiarity with package managers:  Apt-get  Homebrew →Dependencies:  Ruby  ImageMagick  PhantomJS  NodeJS  NPM sudo apt-get install ruby-full

How to install and configure →Run `wraith setup` →Edit configs/capture.yaml →Optional: edit configs/spider.yaml
