From 2deb845cbc6fbe7cd3a97e8227f304224022cf44 Mon Sep 17 00:00:00 2001 From: John O'Keefe Date: Fri, 13 Feb 2026 17:42:02 -0500 Subject: [PATCH] Phase 0: Fix test infrastructure - Fix critical bug in test_helpers.go (dead code, wrong return type) - Add test_helpers_db.go with 6 new helper functions: * verifyDeviceCreated, verifyDeviceDeleted * verifyUserField, verifyMediaItemInDB, verifyMediaItemDeleted * createTestLibraryWithFolder - Impact: All tests can now create users reliably - Create Phase 1 example (phase1_example_test.go) demonstrating: * Struct-based assertions replacing map[string]interface{} * Database verification after mutations * Type-safe compile-time error detection - Impact: Template pattern for remaining 500+ conversions This work transforms brittle map-based tests into reliable struct-based assertions with database verification, preventing silent API changes and data corruption bugs. --- cmd/server/tests/phase1_example_test.go | 88
