Unit tests are an important componant in the CartoWeb development environment. The framework used for unit testing is based on PHPUnit2, a PEAR package. For more informations abouth PHPUnit2, see http://pear.php.net/reference/PHPUnit2-2.0.3/

the existing hierarchy they are testing. For instance, the tests
