### Quick Start: Mocking ClickHouse Queries in Go

Source: https://github.com/srikanthccv/clickhouse-go-mock/blob/main/README.md

Demonstrates how to use clickhouse-go-mock to mock a ClickHouse database connection and execute a query. It sets up expectations for a specific SQL query with arguments and verifies that the mock received the expected calls.

```go
package main

import (
	"context"
	"log"

	"github.com/ClickHouse/clickhouse-go/v2"
	cmock "github.com/srikanthccv/ClickHouse-go-mock"
)

type Video struct {
	Name    string `db:"name"`
	Title   string `db:"title"`
	Content string `db:"content"`
}

func fetchVideos(conn clickhouse.Conn) (*Video, error) {
	var video Video
	if _, err := conn.Query(context.TODO(), "SELECT name, title, content FROM videos WHERE name LIKE ?", "%Cocomelon%"); err != nil {
		return nil, err
	}
	return &video, nil
}

func main() {
	mock, err := cmock.NewClickHouseNative(nil)
	if err != nil {
		log.Fatalf("an error '%s' was not expected when opening a stub database connection", err)
	}

	mock.ExpectQuery("SELECT name, title, content FROM videos WHERE name LIKE ?").WithArgs("%Cocomelon%")
	_, err = fetchVideos(mock)
	if err != nil {
		log.Fatalf("an error '%s' was not expected when querying a statement", err)
	}

	if err := mock.ExpectationsWereMet(); err != nil {
		log.Fatalf("there were unfulfilled expectations: %s", err)
	}
}
```
