The mysqli extension tests

To run the tests, a test database must be created in the MySQL command-line:

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.

# 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.
