FakeAWS

A minimal implementation of AWS as a Rack app, for testing and development.

This is designed to pair nicely with AWSRaw.

Add this line to your application's Gemfile:

gem 'fake_aws'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fake_aws

So far there's only a tiny bit of S3 implemented, but it's well tested and fairly easy to extend. Pull requests for more features are welcome.

The easiest way to try this out is with Faraday:

connection = Faraday.new do |faraday|
  faraday.adapter :rack, FakeAWS::S3::RackApp.new('root_directory')
end

The root directory you provide is used to store S3 objects and metadata.

For example, the following PUT Object request:

connection.put do |request|
  request.url("http://s3.amazonaws.com/test_bucket/test_path/test_file.txt")
  request.headers["Content-Type"] = "text/plain"
  request.body = "Hello, world!"
end

will create a file root_directory/test_bucket/test_path/test_file.txt.

It will also create root_directory/test_bucket/test_path/test_file.txt.metadata.json, which holds the metadata for the file as a JSON hash.

Path-style, virtual-hosted-style, and CNAME-style requests are supported for all operations.

No authentication or security is implemented.

Content-Type and x-amz-metadata headers are stored and returned.

• GET Object
• PUT Bucket
• PUT Object

Pull requests for other operations are welcome!

1. Fork it

4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

• Implement GET Bucket requests
• Improve the response headers (Content-Length, ETag, etc.)
• Check signing of requests
• Handle PUT Object Copy requests
