awskit-s3-sim

awskit-s3-sim provides a deterministic in-memory S3 implementation for tests. It implements the synchronous Awskit_s3.S client shape and does not perform network IO.

The public entrypoint is Awskit_s3_sim.

Test Surface

Awskit_s3_sim includes object, bucket, multipart, and presigned operation modules matching runtime-backed S3 clients. It also exposes test-oriented helpers:

• controllable clock
• shared in-memory store
• object metadata and body inspection
• operation history
• deterministic and pseudo-random fault injection

Example

let credentials =
  Awskit.Credentials.create_exn
    ~access_key_id:"AK"
    ~secret_access_key:"SK"
    ()
in
let clock = Awskit_s3_sim.Clock.create () in
let store = Awskit_s3_sim.create_store ~clock () in
let conn = Awskit_s3_sim.connect store ~credentials in

ignore
  (Awskit_s3_sim.Bucket.create conn ~bucket:"test-bucket" ()
   |> Result.get_ok);

ignore
  (Awskit_s3_sim.Object.put_string conn
     ~bucket:"test-bucket"
     ~key:"hello.txt"
     "hello"
   |> Result.get_ok)
