Unit tests

Using unit tests

Although the coverage is far from complete, there are already quite a lot of unit tests for the TYPO3 Core. Anytime something is changed in the Core, all existing unit tests must be run to ensure that nothing was broken.

Adding unit tests

The use of unit tests is strongly encouraged. Every time a new feature is introduced or an existing one is modified, a unit test should be added.

Conventions for unit tests

Unit tests should be as concise as possible. Since the setUp() and tearDown() methods always have the same responsibility, these methods do not need a documentation block.

Since unit tests never return anything, they do not need an @return tag.
