Simpletesting Drupal and a Simpletest Snippet
There is no question that test driven development is coming to Drupal. And it may be sooner than anyone expected.
Last week at Drupalcon 2008 Dries challenged the community: Provide 100% test coverage for Drupal core by mid may, and the code freeze can be pushed off until November.
So to help you get started in your testing - I've attached a Komodo snippet that will help create a .test file stub.
Don't know what to do with that? Want to start writing your own tests for your own modules? Great! - Check out these great resources.
