From ac947ffcfd455b556289ec561521afb7c12c88a3 Mon Sep 17 00:00:00 2001 From: Test Improver Date: Mon, 13 Apr 2026 01:15:47 +0000 Subject: [PATCH] test: add unit tests for deps/_utils.py helpers (0% -> ~95%) Add 48 unit tests covering all 8 helper functions in src/apm_cli/commands/deps/_utils.py: - _scan_installed_packages: directory traversal for GitHub/ADO layouts - _is_nested_under_package: sub-package detection - _count_primitives: counts prompts, instructions, agents, skills, hooks - _count_package_files: context and workflow file counting - _count_workflows: wrapper around _count_package_files - _get_detailed_context_counts: per-type breakdown of context files - _get_package_display_info: display string from apm.yml - _get_detailed_package_info: full info dict including error handling Tests use tmp_path fixtures for filesystem isolation. Includes edge cases: missing directories, empty dirs, hidden dirs, exception handling, and directory naming quirks (context vs contexts).
