Not sure if we need them in this project. We are testing the config and tracing integration, not GORM itself. Those drivers belong to the tests in GORM project, not here. ie. As long as one of the drivers works, the integration of GORM works.

Yes, it does increase the cost of testing. So i just need to keep the following code?

func provideDialector(conf *databaseConf) (gorm.Dialector, error) {
	drivers := map[string]func(dsn string) gorm.Dialector{
		"mysql":      mysql.Open,
		"sqlite":     sqlite.Open,
		"postgres":   postgres.Open,
		"sqlserver":  sqlserver.Open,
		"clickhouse": clickhouse.Open,
	}
	if driver, ok := drivers[conf.Database]; ok {
		return driver(conf.Dsn), nil
	}
	return nil, fmt.Errorf("unknow database type %s", conf.Database)
}
