mock-aws-s3¶ ↑

This is a simple gem for mocking out the AWS::S3 library, so that no calls to the Amazon S3 service during tests.

Usage is simple, just add the gem to your bundle, and require it in your spec_helper.rb:

require 'mock-aws-s3'

From there on, all (supported) calls to AWS::S3::S3Object will be proxied to file operations in a temp directory on your disk. So these commands:

AWS::S3::S3Object.store 'key', 'some data', 'bucket'
AWS::S3::S3Object.exists?('key', 'bucket')
AWS::S3::S3Object.value 'key', 'bucket'
AWS::S3::S3Object.url_for 'key', 'bucket'
AWS::S3::S3Object.delete('key', 'bucket')

… will result in a file being created on disk at ./tmp/mock-aws-s3/bucket/key, with contents: "some data". A File.exists?() check will be performed on that file, the content of the file will be returned, a local file uri will be return and then it will be deleted.

If you are using Rails, the Rails.root directory will be used: Rails.root.join('tmp').

• Fork the project.

• Make your feature addition or bug fix.

• Add spec for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
