Test/EVSE/GPL/php-5.6.40/ext/pdo_mysql/tests

You must set the following environment variables to run the tests:

PDO_MYSQL_TEST_DSN - DSN
For example: mysql:dbname=test;host=localhost;port=3306

PDO_MYSQL_TEST_HOST - database host
PDO_MYSQL_TEST_DB - database (schema) name
PDO_MYSQL_TEST_SOCKET - database server socket
PDO_MYSQL_TEST_ENGINE - storage engine to use
PDO_MYSQL_TEST_USER - database user
PDO_MYSQL_TEST_PASS - database user password
PDO_MYSQL_TEST_CHARSET - database charset

NOTE: if any of PDO_MYSQL_TEST_[HOST|DB|SOCKET|ENGINE|CHARSET] is
part of PDO_MYSQL_TEST_DSN, the values must match. That is, for example,
for PDO_MYSQL_TEST_DSN = mysql:dbname=test you MUST set PDO_MYSQL_TEST_DB=test.
