You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: warehouse.go
    path of file: ./repos/rudder-server/cmd/rudder-cli/warehouse
    
    the code of the file until where you have to start completion: package warehouse

)

type QueryResult struct {
	Columns []string
	Values  [][]string
}

type QueryInput struct {
	DestID       string
	SourceID     string
	SQLStatement string
}

type ConfigurationTestInput str
    
func ConfigurationTest(c *cli.Context) (err error) {
	reply := ConfigurationTestOutput{}

	input := ConfigurationTestInput{
		DestID: c.String("dest"),
	}

	err = client.GetUDSClient().Call("Warehouse.ConfigurationTest", input, &reply)
	if err != nil {
		return
	}

	if reply.Valid {
		fmt.Printf("Successfully validated destID: %s \n", input.DestID)
	} else {
