Embedded MySQL server for use in tests. It allows testing your Java or other JVM based application against a real MySQL server with no external dependencies to deploy or manage.

Add the library as a test dependency:

<dependency>
    <groupId>io.airlift</groupId>
    <artifactId>testing-mysql-server</artifactId>
    <version>8.0.12-2</version>
    <scope>test</scope>
</dependency>

Use it in your tests:

@Test
public void testDatabase()
        throws Exception
{
    try (TestingMySqlServer server = new TestingMySqlServer("testuser", "testpass", "testdb");
            Connection connection = DriverManager.getConnection(server.getJdbcUrl("testdb"));
            Statement statement = connection.createStatement()) {
        statement.execute("CREATE TABLE test_table (id bigint PRIMARY KEY)");
        statement.execute("INSERT INTO test_table (id) VALUES (123)");
    }
}

The server takes a few seconds to startup, so you will likely want to leave it running between tests. Make sure the server is always shutdown (by calling the close() method or using try-with-resources), otherwise the mysqld process will stay running after the JVM exits.
