+You can run unit tests with [PHPUnit](https://phpunit.de/):
+
+```bash
+phpunit
+```
+
+Some tests require access to a MySQL database.
+You can specify the database credentials in environment variables:
+
+```bash
+USER=database_user PASS=database_password DB=database_name phpunit
+```
+
+**Warning**: This will empty all the tables! Never use this on a production database.
