- 5. HISTORY OF DRUPAL TESTING Drupal Testing: D6 core – Simpletest Application specific testing - Manual Tests - Written test cases – Word documents - The spreadsheet of pain. (Checklist) Challenges - Testing different browsers Reproducible results Providing a record Doesn’t test integration with 3rd party API (backend functionality)
- 6. CONTINUOUS INTEGRATION: Continuous Integration (CI) implements continuous processes of applying quality control — small pieces of effort, applied frequently. Continuous integration aims to improve the quality of software, and to reduce the time taken to deliver it, by replacing the traditional practice of applying quality control after completing all development. Continuous Integration emerged in the Extreme Programming (XP) community, and XP advocates Martin Fowler and Kent Beck first wrote about continuous integration circa 1999.

- 14. What is Selenium? •Selenium automates browsers. That's it. What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web- based administration tasks can (and should!) also be automated as well. •Selenium has the support of some of the largest browser vendors who have taken (or are taking) steps to make Selenium a native part of their browser. It is also the core technology in countless other browser automation tools, APIs and frameworks. • Goes through every page • Makes sure header, footer, logos, etc • All branding elements in place
- 15. Functional Test PHPUnit • Project Airbox • Checkout process that involves passing customer information to third party banking API, passes back customer ID • Months after completion, API changes broke the application • PHPUnit figures out how and where the problem is • More importantly, is there a problem? • Major time saver for detective work • -- bootstrap option to make use of forked upal without SUT • https://github.com/chriscalip/upal • http://drupal.org/node/1567500 • actually installs a complete Drupal site like the regular Drupal installer for every test being executed, using a random database prefix and some logic baked into Drupal's (regular runtime) core that re-routes all HTTP requests originating from WebTestBase into the "child site under test" (the db-prefixed one). Based on that, every test is able to specify additional modules to install into that child site, in order to test various
