[PATCH 10/14] test: update device authentication tests - Change Kobo sync endpoints to use URL token authentication - Update OPDS tests to use device tokens instead of user tokens - Support both Bearer and query parameter authentication methods - Return error when test user already exists instead of deleting - Prevent test interference from cleanup operations - Improve test isolation and

2deb845cbc6fbe7cd3a97e8227f304224022cf44 Mon Sep 17 00:00:00 2001 From: John O'Keefe Date: Fri, 13 Feb 2026 17:42:02 -0500 Subject: [PATCH 11/14] 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

TestUpdateDevice to use handlers.DeviceUpdateRequest - Add database verification after device update: * Query DB to verify sync_enabled, sync_frequency actually updated * Ensures data integrity - API says success, DB confirms it - Impact: Compile-time safety for device endpoints, data integrity verification Pattern: Replaces map[string]interface{} with type-safe structs, ensures API changes caught
