From 99ada61669833e27d18609c8ae5ab6c118ffee2c Mon Sep 17 00:00:00 2001 From: Jonatan Dahl Date: Fri, 28 Nov 2025 17:42:39 -0500 Subject: [PATCH 1/3] feat: add unit testing with mocked git and github CLIs - Add GitClient and GitHubClient interfaces for dependency injection - Refactor git, github, and stack packages to use interface-based clients - Update all command functions to accept client parameters (no backward compatibility) - Create comprehensive test utilities with mocks and fixtures using testify - Add package-level tests for stack (70.8% coverage), git, and github packages - Add command-level tests for new, sync, and status commands - Add testify dependency to go.mod - Update all cmd files (new, sync, status, parent, prune, rename, reparent, worktree, root) to use dependency injection All git and github CLI calls are now mockable for fast, isolated unit tests. --- cmd/new.go | 43 ++-- cmd/new_test.go | 231 +++++++++++++++++++++ cmd/parent.go | 10 +- cmd/prune.go | 33 +--
