I seem to recall reading about an Amazon S3-compatible test server that you could run on your own server for unit tests or whatever. However, I've just exhausted my patience looking for this with both Google and AWS. Does such a thing exist? If not, I think I'll write one.

Note: I'm asking about Amazon S3 (the storage system) rather than Amazon EC2 (cloud computing).

Are you thinking of Park Place?

adobe/S3Mock: A simple mock implementation of the AWS , S3Mock. Introduction. S3Mock is a lightweight server that implements parts of the Amazon S3 API. It has been created to support hermetic testing and reduces  S3 Browser is a standalone application on Windows. There is a paid pro version as well, giving you more options (you actually will need those features), but first test the water and if you like this application, you can buy it.

I think moto ( is the perfect tool for your unittests. Moto mocks all accesses to S3, SQS, etc. and can be used in any programming language using their web server.

It is trivial to setup, lightweight and fast.

From moto's README:

Imagine you have the following code that you want to test:

import boto
from boto.s3.key import Key

class MyModel(object):
    def __init__(self, name, value): = name
        self.value = value

    def save(self):
        conn = boto.connect_s3()
        bucket = conn.get_bucket('mybucket')
        k = Key(bucket)
        k.key =

Take a minute to think how you would have tested that in the past. Now see how you could test it with Moto:

import boto
from moto import mock_s3
from mymodule import MyModel

def test_my_model_save():
    model_instance = MyModel('steve', 'is awesome')

    conn = boto.connect_s3()
    assert conn.get_bucket('mybucket').get_key('steve') == 'is awesome'

Amazon S3 does not support server-side scripting. You can use the following quick procedures to configure an S3 bucket for static website hosting in the Amazon S3 console.

Advanced client stubbing in the AWS SDK for Ruby Version 3, The AWS SDK for Ruby provides a robust set of features for stubbing your clients, to make unit tests easier and less s3 = true) However, for example purposes, the file is standalone.). Reading and Writing Data Sources From and To Amazon S3. The following example illustrates how to read a text file from Amazon S3 into an RDD, convert the RDD to a DataFrame, and then use the Data Source API to write the DataFrame into a Parquet file on Amazon S3: Specify Amazon S3 credentials.

EUCALYPTUS - Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems - is an open-source software infrastructure for implementing "cloud computing" on clusters. The current interface to EUCALYPTUS is compatible with Amazon's EC2 interface, but the infrastructure is designed to support multiple client-side interfaces.

Note that, according to the documentation, Eucalypus includes a reimplementation not only of the EC2 interface but also the S3 storage system. That storage component is called Walrus. (
