From 5cf3fc24c6006685e0d8710f6aedb30b4525cf32 Mon Sep 17 00:00:00 2001 From: = <=> Date: Fri, 3 Oct 2025 18:03:27 +0200 Subject: [PATCH] Add LocalStack integration for local S3 testing - Add LocalStack Docker Compose configuration for S3 emulation - Add automatic bucket creation on LocalStack startup (ceti-data, ceti-data-test, ceti-dev) - Add pytest fixtures for S3 testing (LocalStack or real AWS) - Add 9 integration tests for S3 upload and deduplication - Update ceti modules to support AWS_ENDPOINT_URL for LocalStack - Add LocalStack warning message in s3upload CLI - Add Makefile targets: test-local, localstack-up/down/clean - Update Python dependencies for Python 3.13 compatibility (mypy, boto3) - Add comprehensive testing documentation (README.md, docs/TESTING.md) Tests can now run locally without AWS credentials using 'make test-local'. LocalStack automatically creates required S3 buckets on startup. Production workflows remain unchanged - code automatically detects LocalStack vs real AWS based on AWS_ENDPOINT_URL environment variable. --- .env.example | 15 ++ .env.localstack | 9 + Makefile | 31 +++ README.md | 55 ++++++ ceti/general_offload.py | 4 +- ceti/s3upload.py | 12 +- ceti/spark/utils.py | 2 +- docker-compose.localstack.yml | 24 +++ docs/TESTING.md | 247 ++++++++++++++++++++++++ scripts/init-localstack.sh | 20 ++ setup.py | 9 +- tests/conftest.py | 101 ++++++++++ tests/test_integration_deduplication.py | 145 ++++++++++++++ tests/test_integration_upload.py | 149 ++++++++++++++ tests/test_s3upload.py | 9 +- 15 files changed, 821 insertions(+), 11 deletions(-) create mode 100644 .env.example create mode 100644 .env.localstack create mode 100644 docker-compose.localstack.yml create mode 100644 docs/TESTING.md create mode 100755 scripts/init-localstack.sh create mode 100644 tests/conftest.py create mode 100644 tests/test_integration_deduplication.py create mode 100644 tests/test_integration_upload.py diff --git a/.env.example b/.env.example new file mode 100644 index 0000000..beb1e6a --- /dev/null +++ b/.env.example @@ -0,0 +1,15 @@ +# Production AWS Configuration Template +# Copy this file to ~/.aws/credentials or set as environment variables +# +# For production use: +# 1.
