AWS S3 unit testing library

S3 makes it possible to write AWS S3 unit tests and integrate them into the Go development work-flow using the go test CLI.

Install: go get github.com/aead/s3

Run S3 tests

1. Install minio S3 server: go get -u github.com/minio/minio
2. Setup TLS:
   • openssl ecparam -genkey -name prime256v1 | openssl ec -out ~/.minio/certs/private.key
   • openssl req -new -x509 -days 3650 -key ~/.minio/certs/private.key -out ~/.minio/certs/public.crt -subj "/C=US/ST=state/L=location/O=organization/CN=domain"
3. Run S3 server: minio server <your-dir>
4. Run S3 tests: go test -v -short github.com/aead/s3 -args -access=your-access-key -secret=your-secret-key -insecure
