+
+When fixing a bug or adding a new feature using test-driven development, it's important to see the test fail first.
+
+You should write your test so it doesn't pass by default or accidentally.
+
+When creating data, such as users or nodes within tests, do so in a way that will force the test to fail, such as explicitly setting the title or published date into a non-default order.
+
+When fixing a bug, write a test that represents the expected outcome when the bug is fixed. This confirms the bug exists and can be replicated.
+
+Then, once the tests pass, you know the feature or fix is working and that it's because of your changes and not for any other reason.
