Add 740 total tests (up from ~200) covering:
- Compile-time interface compliance for all providers
- GetCapabilities assertions for every provider
- Parse function edge cases: empty, malformed, single-entry, multi-entry
- apt: extract inline parse logic into testable functions (parsePolicyCandidate,
parseUpgradeSimulation, parseHoldList, parseOwner, parseSourcesLine)
- dnf/rpm: edge cases for both dnf4 and dnf5 parsers, normalize/parseArch
- pacman/aur: parseUpgrades, parseGroupPkgSet, capabilities
- apk: parseUpgradeSimulation, parseListLine, SupportsDryRun
- flatpak/snap: semverCmp, stripNonNumeric edge cases
- pkg/ports: all parse functions with thorough edge cases
Every provider now has:
- Interface compliance checks (what it implements AND what it doesn't)
- Capabilities test via snack.GetCapabilities()
- Parse function unit tests with table-driven edge cases
Native Go implementation using the AUR RPC v5 API for search/info
queries and git+makepkg+pacman for building and installing packages.
Implements:
- Manager (full: Install, Remove, Purge, Upgrade, Update, List, Search,
Info, IsInstalled, Version)
- VersionQuerier (LatestVersion, ListUpgrades, UpgradeAvailable, VersionCmp)
- Cleaner (Autoremove via pacman, Clean build dir)
- PackageUpgrader (UpgradePackages)
Key design decisions:
- No CLI wrapper (paru/yay) — uses AUR RPC API directly + git clone
- Packages are built with makepkg and installed via pacman -U
- Foreign packages (pacman -Qm) are treated as AUR packages for List
- Batch RPC queries (rpcInfoMulti) for efficient upgrade checks
- Configurable build directory and makepkg flags
- Not added to detect.Default() candidates (AUR supplements pacman,
not replaces it) but available via detect.ByName("aur")
