From f8e365ea1739bfa4072ac984da7c1d728e8cdae5 Mon Sep 17 00:00:00 2001 From: yaythomas Date: Tue, 16 Sep 2025 12:47:29 -0700 Subject: [PATCH 1/3] feat: add initial operations Initial test framework to run AWS Durable Functions locally in a unit test environment. Includes validation for: - step - wait - run_in_child_context - create_callback - wait_for_callback - wait_for_condition - parallel - map --- .github/workflows/ci.yml | 37 + .gitignore | 26 +

00:00:00 2001 From: yaythomas Date: Wed, 24 Sep 2025 01:23:24 -0700 Subject: [PATCH 2/3] chore: rename to aws-durable-execution-sdk-python MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Renamed the external module references from aws_durable_functions_sdk_python to aws_durable_execution_sdk_python and updated the testing module name from aws_durable_functions_sdk_python_testing to aws_durable_execution_sdk_python_testing throughout the entire codebase. Also update Lambda Service API to include new durable_execution_arn arg. 1. Updated all import statements across 52 files including: - All Python source files in src/aws_durable_execution_sdk_python_testing/ - All test files in tests/ - Documentation files (README.md, CONTRIBUTING.md) 2. Fixed API compatibility issues that arose from the module rename: - Updated InMemoryServiceClient.checkpoint() method to include the new durable_execution_arn parameter - Updated InMemoryServiceClient.get_execution_state() method to include the new durable_execution_arn parameter - Updated corresponding test cases to use the new method signatures - Added appropriate # noqa: ARG002 comments for unused parameters in the in-memory implementation 3. Maintained code quality standards: - All 406 tests pass ✅ - Type checking passes ✅ - Code formatting passes ✅ - Test coverage remains above 99% (99.15%) ✅ --- .gitignore | 3 ++ CONTRIBUTING.md | 2 +-
