Kernel: functional testing with the kernel bootstrapped, access to the database and only a few loaded modules. If you want to apply TDD in Drupal, the only way is to use unit tests for the bulk of the tests, switch to kernel tests when mocking the Drupal API becomes too complex, and use a few functional tests to make sure the UI works as designed. Super contrived! Online resources for testing unique custom modules are few and far between, and what does exist is often contrived. It's important to understand how Drupal uses a few keys terms. With version 8 looming on the horizon, Danny ups our development game with automated testing of Drupal 8 modules - write functional tests like a pro! The error displayed will show you what is missing. My best advice is to try and include what you think will be needed and run the test expecting the test to fail. It will not appear in Admin > Extend, you cannot enable it using Drush, but you can enable it in tests.

The other way, is a bit of a shortcut for installing schema required for specific entities. The my_module_service_test submodule provides a new label/message pair. And so, perhaps expectedly, once I decided to dive in, I encountered a number of problems along the way.

Our ::setUp() method does a few interesting things. I don't have a lot of experience writing new automated tests for custom Drupal modules. Learning more about tests In a properly designed module, testing the API of your module should take precedence over any interaction with the UI. When we wrote a functional test earlier, it was enough that we listed the module name in the $modules static class variable. So is that it, then? Notice that it is very similar to the clip above about Unit tests: Kernel tests fetch the database information from core/phpunit.… To be honest, I strive for the simplest tests with the least number of dependencies. Drupal is open source software maintained and developed by a community of 1,000,000+ users and developers. Thus, we'll check the return values with ::assertFalse().
