One way to generate mocks for AWS SDK is to use mockgen with go generate command.
Example below shows generating the mock for CloudWatchLogsAPI and placing mock into mocks directory.
package cloudwatchlogs
import (
"github.com/golang/mock/gomock"
"github.com/flowlab/log/pkg/mocks"
"testing"
)
//go:generate mockgen -package=mocks -destination ../mocks/mock_cloudwatchlogsiface.go github.com/aws/aws-sdk-go/service/cloudwatchlogs/cloudwatchlogsiface CloudWatchLogsAPI
func TestPutRetentionPolicy(t *testing.T) {
ctrl := gomock.NewController(t)
defer ctrl.Finish()
mockCloudWatchLogsAPI := mocks.NewMockCloudWatchLogsAPI(ctrl)
mockCloudWatchLogsAPI.EXPECT().
PutRetentionPolicyWithContext(gomock.Any(), gomock.Any()).
Return(nil, nil).
Times(1) // test code and assertions
}
go generate is not part of go build. It contains no dependency analysis and must be run explicitly before running go build.
