From cb5c198d16e97b54e2bbe2c59e9af3593c2191ad Mon Sep 17 00:00:00 2001 From: Xi Xu Date: Wed, 4 Jun 2025 18:55:53 +0800 Subject: [PATCH] Refactor tests and enhance coverage for conflict resolution and edge cases - Removed outdated tests for missing lines in core.py. - Added comprehensive tests for conflict resolution functionality, including various resolution strategies and edge cases. - Improved error handling tests for archive creation and extraction processes. - Enhanced unit tests for basic functionality and convenience functions with pytest markers. - Introduced tests for unique filename generation and conflict handling scenarios. - Added edge case tests for archive extraction and error conditions to improve overall test coverage. --- .github/workflows/publish_docs.yml | 8 +- pyproject.toml | 21 +- src/tzst/__init__.py | 6 +- src/tzst/cli.py | 137 ++++++- src/tzst/core.py | 261 ++++++++++++- tests/cli/test_cli.py | 135 ++++++- tests/conftest.py | 11 + tests/test_cli_missing_lines.py | 405 -------------------- tests/test_conflict_resolution.py | 463 +++++++++++++++++++++++ tests/test_conftest_fixtures.py | 216 ----------- tests/test_core_edge_cases.py | 253 +++++++++++++ tests/test_core_missing_lines.py | 395 ------------------- tests/test_core_missing_lines_fixed.py | 374 ------------------ tests/unit/test_archive_basics.py | 5 + tests/unit/test_convenience_functions.py | 4 + tests/unit/test_security_and_errors.py | 10 +- 16 files changed, 1284 insertions(+), 1420 deletions(-) delete mode 100644 tests/test_cli_missing_lines.py create mode 100644 tests/test_conflict_resolution.py delete mode 100644 tests/test_conftest_fixtures.py create mode 100644 tests/test_core_edge_cases.py delete mode 100644 tests/test_core_missing_lines.py delete mode 100644 tests/test_core_missing_lines_fixed.py diff --git a/.github/workflows/publish_docs.yml b/.github/workflows/publish_docs.yml index 29b1edc..b111185 100644 --- a/.github/workflows/publish_docs.yml +++ b/.github/workflows/publish_docs.yml @@ -1,12 +1,6 @@ name: Publish Documentation -on: -
