HOW TO RUN THE TESTS
Make sure you have PHPUnit installed and that you installed all composer dependencies (run composer update in the repo base directory).
Run PHPUnit in the yii repo base directory.
phpunit
You can run tests for specific groups only:
phpunit --group=mysql,base,i18n
You can get a list of available groups via phpunit --list-groups.
TEST CONFIGURATION
PHPUnit configuration is in phpunit.xml.dist in repository root folder.
You can create your own phpunit.xml to override dist config.
Database and other backend system configuration can be found in unit/data/config.php
adjust them to your needs to allow testing databases and caching in your environment.
You can override configuration values by creating a config.local.php file
and manipulate the $config variable.
For example to change MySQL username and password your config.local.php should
contain the following:
<?php
$config['databases']['mysql']['username'] = 'yiitest';
$config['databases']['mysql']['password'] = 'changeme';
