S3Mock is a lightweight server that implements a subset of the Amazon S3 API for local integration testing, removing the need for real AWS infrastructure. It can be started as a Docker image, Testcontainer, JUnit Jupiter extension, or TestNG listener.
Use cases
- test S3-dependent code locally without AWS
- run S3 mock in integration tests with Testcontainers
- start a fake S3 endpoint for JUnit tests
- develop against S3 API offline
- test S3 uploads and downloads with AWS CLI
- mock S3 for CI pipelines
When to choose
- you need a local S3-compatible endpoint for automated tests
- you want to avoid AWS costs and network dependency in CI
- you use Java/Kotlin with JUnit or Testcontainers
When to avoid
- you need full S3 API coverage or production parity
- you need real S3 features like cross-region replication or IAM policies
- you need a persistent production object store
