Hi @Shokoufehsafa,

While we strive to provide comprehensive examples and guidance, it's impossible for us to create examples for every possible operation due to the vast scope of the SDK. Generally, Go developers are expected to be familiar with mocking techniques and dependency inversion, which are integral parts of testing in Go.

However, we do provide the github.com/aws/aws-sdk-go/service/sqs/sqsiface package, which offers an interface for the SQS API client that can be easily mocked for testing purposes.

To help you get started, here's a basic example that demonstrates how to mock the SendMessage function using this interface:

package main

import (
	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/service/sqs"
	"github.com/aws/aws-sdk-go/service/sqs/sqsiface"
	"github.com/stretchr/testify/assert"
	"testing"
)

type mockSQSClient struct {
	sqsiface.SQSAPI
}

func (m *mockSQSClient) SendMessage(input *sqs.SendMessageInput) (*sqs.SendMessageOutput, error) {
	return &sqs.SendMessageOutput{MessageId: aws.String("mockMessageId")}, nil
}

func TestSendMessage(t *testing.T) {
	mockClient := &mockSQSClient{}

	params := &sqs.SendMessageInput{
		MessageBody: aws.String("test message"),
		QueueUrl:    aws.String("https://sqs.us-west-2.amazonaws.com/123456789012/MyTestQueue"),
	}

	resp, err := SendMessage(mockClient, params)

	assert.NoError(t, err)
	assert.Equal(t, *resp.MessageId, "mockMessageId")
}

Thanks,
Ran~
