+# Testing
+
+```
+composer install --dev
+phpunit --bootstrap=vendor/autoload.php tests
+```
+
+The default database connection details are:
+
+- hostname: localhost
+- database: ohanzee
+- username: ohanzee
+- password: (empty)
+
+These values can be modified by creating a `.env` file in the root of the project:
+
+```ini
+PHPUNIT_TEST_HOSTNAME=server
+PHPUNIT_TEST_DATABASE=testing
+PHPUNIT_TEST_USERNAME=jane
+PHPUNIT_TEST_PASSWORD=likesblue
+```
+
+The `.env` file is a standard ini file and will be loaded using [dotenv](https://github.com/vlucas/phpdotenv).
+
+Any of the parameters can also be passed directly on the commandline:
+
+```
+PHPUNIT_TEST_USERNAME=joe PHPUNIT_TEST_PASSWORD=likesgreen \
+  phpunit --bootstrap=vendor/autoload.php tests
+```
