| # The mysqli extension tests | |
| To run the tests, a test database must be created in the MySQL command-line: | |
| ```sql | |
| CREATE DATABASE test; | |
| ``` | |
| The test suite will create the necessary tables for testing, and then delete them when testing is complete. Creating a dedicated table prior to running the tests is unnecessary. There are default values for `MYSQL_TEST_HOST`, `MYSQL_TEST_USER`, `MYSQL_TEST_DB` and `MYSQL_TEST_PASSWD`. If your values differ from the defaults, then environment variables must be set. | |
| ```bash | |
| # Database host | |
| # Default: localhost | |
| MYSQL_TEST_HOST | |
| # Database port | |
| MYSQL_TEST_PORT | |
| # Database user | |
| # Default: root | |
| MYSQL_TEST_USER | |
| # Database user password | |
| # The default password is empty (no password). | |
| MYSQL_TEST_PASSWD | |
| # Database name | |
| # Default: test | |
| MYSQL_TEST_DB | |
| # Storage engine to use | |
| MYSQL_TEST_ENGINE | |
| # Database server socket | |
| MYSQL_TEST_SOCKET | |
| ``` | |
| ## MySQL User Permissions | |
| The MySQL user used to run the tests must have full permissions on the test database. | |
