I have this test:

@SpringBootTest
class ChatGPTServiceTest {

    @Autowired
    private ChatGPTService chatGPTService;

    @Test
    void createImage() throws JsonProcessingException {

        chatGPTService.createImage("Antonio Escohotado: la actualidad de su pensamiento");
        //assertNotNull(image);


    }

}

but I have this error when running the test:

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'dataSourceScriptDatabaseInitializer' defined in class path resource [org/springframework/boot/autoconfigure/sql/init/DataSourceInitializationConfiguration.class]: Unsatisfied dependency expressed through method 'dataSourceScriptDatabaseInitializer' parameter 0: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception with message: Failed to determine a suitable driver class
