// S3API provides an interface to enable mocking the
// s3.S3 service client's API operation,
// paginators, and waiters. This make unit testing your code that calls out
// to the SDK's service client's calls easier.
//
// The best way to use this interface is so the SDK's service client's calls
// can be stubbed out for unit testing your code with the SDK without needing
// to inject custom request handlers into the SDK's request pipeline.
//
// // myFunc uses an SDK service client to make a request to
// // Amazon Simple Storage Service.

// // Make svc.AbortMultipartUpload request
// }
//
// func main() {
// sess := session.New()
// svc := s3.New(sess)
//
// myFunc(svc)
// }
//
// In your _test.go file:
//
// // Define a mock struct to be used in your unit tests of myFunc.
// type mockS3Client struct {
// s3iface.S3API
// }
// func (m *mockS3Client) AbortMultipartUpload(input *s3.AbortMultipartUploadInput) (*s3.AbortMultipartUploadOutput, error) {
