=== mysql_test ===

- The CppunitTest_mysql_test unit test can be used to test the mysqlc
  library with any versions of mysql or mariadb server of your choice.
  
- This test does not run automatically. It can be triggered with setting
  the environment variable "CONNECTIVITY_TEST_MYSQL_DRIVER".
  
- The environment variable should contain a URL of the following format:
  [user]/[passwd]@sdbc:mysql:mysqlc:[host]:[port]/db_name

- tl;dr:

  podman pull mariadb/server
  podman run --name=mariadb -e MYSQL_ROOT_PASSWORD=foobarbaz -p 127.0.0.1:3306:3306 mariadb/server
  podman exec -it mariadb /bin/bash -c "echo -e CREATE DATABASE test | /usr/bin/mysql -u root"
  (cd connectivity && make -srj8 CppunitTest_connectivity_mysql_test CONNECTIVITY_TEST_MYSQL_DRIVER="root/foobarbaz@sdbc:mysql:mysqlc:127.0.0.1:3306/test")
  podman stop mariadb
  podman rm mariadb
