From 7b60f92a48b4ff54604e8179503488800866ca6f Mon Sep 17 00:00:00 2001 From: Warry Date: Mon, 29 Dec 2025 20:54:26 +0100 Subject: [PATCH] feat: Refactor playlist management, error handling, and testing infrastructure - Improved playlist item handling with pagination, error logging, and dedicated request hooks. - Consolidated reusable helpers for track ID normalization, playlist validation, and removal logic. - Enhanced error handling by introducing `PlaylistNotFound` and `UserNotAuthenticated` exceptions. - Refined Pytest `qapp` fixture for headless CI compatibility and session-scoped reuse. - Replaced redundant fixtures in multiple test files for consistency. - Improved playlist management GUI with detailed debug logging for notifications and operations. - Added `deptry` configuration to handle transitive dependencies and ignored exclusions. - Updated Pytest and Tox configurations for consistent environment setup during CI/CD runs. --- pyproject.toml | 6 + tests/conftest.py | 27 ++- tests/test_delimiters_category.py | 9 -
