The tests validate default and custom initialization, attribute setting, and the functionality of helper methods, contributing to improved reliability and maintainability of the codebase. --- tests/test_config.py | 368 ++++++++++++++++++++++++++++++++++++++++++ tests/test_context.py | 122 ++++++++++++++ tests/test_main.py | 129 +++++++++++++++ 3 files changed, 619 insertions(+) create mode 100644 tests/test_config.py create mode 100644 tests/test_context.py create mode 100644 tests/test_main.py diff --git a/tests/test_config.py b/tests/test_config.py new file mode 100644 index 0000000..879b1e3 --- /dev/null +++ b/tests/test_config.py @@ -0,0 +1,368 @@ +from __future__ import annotations + +from pathlib import Path +from unittest.mock import patch + +import pytest + +from depkeeper.config import ( + DepKeeperConfig, + discover_config_file, + load_config, + _parse_section, + _pyproject_has_depkeeper_section, + _read_toml, +) +from depkeeper.exceptions import ConfigError + + +@pytest.mark.unit +class TestDepKeeperConfig: + """Tests for DepKeeperConfig dataclass.""" + + def test_default_initialization(self) -> None: + """Test DepKeeperConfig initializes with correct defaults.""" + config = DepKeeperConfig() + + assert config.check_conflicts is True + assert config.strict_version_matching is False + assert config.source_path is None + + def test_custom_initialization(self) -> None: + """Test DepKeeperConfig accepts custom values.""" + test_path = Path("/test/config.toml") + + config = DepKeeperConfig( + check_conflicts=False, + strict_version_matching=True, + source_path=test_path, + ) + + assert config.check_conflicts is False + assert config.strict_version_matching is True + assert config.source_path == test_path + + def test_to_log_dict(self) -> None: + """Test to_log_dict returns configuration without metadata.""" + config = DepKeeperConfig( + check_conflicts=False, + strict_version_matching=True, + source_path=Path("/test/path.toml"), + ) + + result = config.to_log_dict() + + assert result == { + "check_conflicts": False, + "strict_version_matching": True, + } + assert "source_path" not in result + + +@pytest.mark.unit +class TestDiscoverConfigFile: + """Tests for discover_config_file function.""" + + def test_explicit_path_priority(self, tmp_path: Path) -> None: + """Test explicit path is used when provided and exists.""" + config_file = tmp_path / "custom.toml" + config_file.write_text("[depkeeper]\n", encoding="utf-8") + + #
