Add migration 016 with two tables for the module system:
- settings_overrides: dotted-path config overrides set via admin UI
- module_state: per-module enabled/disabled state
Update testutil.TruncateAll to include new tables.
Ref #94
Migration 014: dag_nodes, dag_edges, dag_cross_edges tables for the
feature-level dependency graph with validation state tracking.
Migration 015: runners, job_definitions, jobs, job_log tables for the
async compute job system with PostgreSQL-backed work queue.
Update TruncateAll in testutil to include new tables.
Add 56 tests covering the core backend packages:
Unit tests (no database required):
- internal/partnum: 7 tests for part number generation logic
(sequence, format templates, enum validation, constants)
- internal/schema: 8 tests for YAML schema loading, property
merging, validation, and default application
Integration tests (require TEST_DATABASE_URL):
- internal/db/items: 10 tests for item CRUD, archive/unarchive,
revisions, and thumbnail operations
- internal/db/relationships: 10 tests for BOM CRUD, cycle detection,
self-reference blocking, where-used, expanded/flat BOM
- internal/db/projects: 5 tests for project CRUD and item association
- internal/api/bom_handlers: 6 HTTP handler tests for BOM endpoints
including flat BOM, cost calculation, add/delete entries
- internal/api/items: 5 HTTP handler tests for item CRUD endpoints
Infrastructure:
- internal/testutil: shared helpers for test DB pool setup,
migration runner, and table truncation
- internal/db/helpers_test.go: DB wrapper for integration tests
- internal/db/db.go: add NewFromPool constructor
- Makefile: add test-integration target with default DSN
Integration tests skip gracefully when TEST_DATABASE_URL is unset.
Dev-mode auth (nil authConfig) used for API handler tests.
