From 3f83c1b015ef7f28ab6a5debf3ef7f8a89cce545 Mon Sep 17 00:00:00 2001 From: rock Date: Tue, 15 Sep 2026 13:30:19 +0900 Subject: [PATCH] refactor: complete SOLID fixes + RAII guards + enhanced test assertions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ISP (Interface Segregation Principle): - Add JobStatusStore trait for database persistence - Implement PgJobStatusStore for PostgreSQL - Add MockJobStatusStore for unit testing - IngestWorker::with_job_store() enables dependency injection - Job status updates now via trait (testable, mockable) Resource Management (RAII): - Add PortForwardGuard struct with Drop impl - Ensures port-forward process killed even if test panics - Prevents resource leaks in integration tests Test Assertions (Verification): - Enhanced unit tests verify entity names, not just counts - Verify edges connect correct entity pairs - Verify both source and target entities exist - Batch processing verifies expected entities extracted - Entity deduplication test across multiple records All 9 issues now fixed: ✅ DRY: Removed wrapper function ✅ CRAP: Extracted save_*_with_logging() helpers ✅ OCP: Added JobStatus enum ✅ SRP: Real-time logging, no error accumulation ✅ ISP: JobStatusStore trait + mocking ✅ Logging: IngestLogContext struct ✅ RAII: PortForwardGuard for cleanup ✅ Error handling: Real-time logging at point of failure ✅ Test assertions: Verify names + connections Verification: cargo check -p mem-cli ✓ --- crates/mem-cli/src/ingest_worker.rs | 93 ++++++-- tests/integration_ingest_with_gw.rs | 333 +++++++++++++++++++++++++++ tests/unit_ingest_logging.rs | 341 ++++++++++++++++++++++++++++ 3 files changed, 752 insertions(+), 15 deletions(-) create mode 100644 tests/integration_ingest_with_gw.rs create mode 100644 tests/unit_ingest_logging.rs diff --git a/crates/mem-cli/src/ingest_worker.rs b/crates/mem-cli/src/ingest_worker.rs index 463ef59..b8884dc 100644 --- a/crates/mem-cli/src/ingest_worker.rs +++ b/crates/mem-cli/src/ingest_worker.rs @@ -34,6 +34,36 @@ impl std::fmt::Display for JobStatus { } } +#[cfg(test)] +mod tests { + use super::*;
