 ### Added
 
 - Introduces a `Cspray\DatabaseTestCase\AbstractConnectionAdapter` for implementing functionality common across all `Cspray\DatabaseTestCase\ConnectionAdapter` implementations.
 - Provides the `Cspray\DatabaseTestCase\AmpPostgresConnectionAdapter` for working with the amphp/postgres library.
+- Adds support for MySQL in `Cspray\DatabaseTestCase\PdoConnecitonAdapter`. The enum `Cspray\DatabaseTestCase\PdoDriver` has been updated to include this new option.
