Testing is important.
|
|
|
|
It allows developers to add new features and edit and refactor existing code without the worry of adding regressions, reduces the reliance on manual testing to discover bugs, and by taking a test-driven approach, your implementation code is leaner as you only write what is needed for your tests to pass.
|
|
|
|
Drupal 7 includes the SimpleTest module for unit and functional testing, whilst Drupal 8 also includes and supports PHPUnit - the defacto PHP testing framework used by other PHP projects, including Symfony and Laravel - making it easier for people to test their code.
|
|
|
|
With testing being one of the Drupal core gates, with tests needing to be included with every new feature or bug fix and core's 100% pass rate policy, testing has become an essential skill when contributing to the core or when working on your own projects.
|
|
|
|
In this talk, we'll cover the methodology and terminology involved with automated testing and then take a test-driven approach to create a new Drupal module.
