From c81ca967e654708a2a7a11e0db5238408a01f788 Mon Sep 17 00:00:00 2001 From: "hsparks.codes" Date: Wed, 3 Dec 2025 10:38:13 +0100 Subject: [PATCH] test: Add integration tests and explain testing strategy Response to @KevinHuSh's review question about mocks. Added: - Integration tests (10 tests) with real CheckpointService and database - Documentation explaining unit tests vs integration tests - Real-world resume scenario test - Comments in unit tests explaining mock usage Integration tests cover: - Actual database operations - Complete checkpoint lifecycle - Resume from crash scenario - Retry logic with real state - Progress calculation with persistence Unit tests (mocked) remain for: - Fast CI/CD feedback (0.04s) - Interface validation - No database dependencies Both test types are valuable and complement each other. --- .../test_checkpoint_service_integration.py | 261 ++++++++++++++++++ .../services/test_checkpoint_service.py | 6 + 2 files changed, 267 insertions(+) create mode 100644 test/integration_test/services/test_checkpoint_service_integration.py diff --git a/test/integration_test/services/test_checkpoint_service_integration.py b/test/integration_test/services/test_checkpoint_service_integration.py new file mode 100644 index 000000000..de5170188 --- /dev/null +++ b/test/integration_test/services/test_checkpoint_service_integration.py @@ -0,0 +1,261 @@ +# +# Copyright 2025 The InfiniFlow Authors.
