configured to sign commits, but signing was failing + - Solution: Added `git config commit.gpgsign false` in test fixtures + - Lesson: Always disable GPG signing in test environments + +2. **Test Directory Cleanup Issues** + - Problem: Tests were failing with `FileNotFoundError` when calling `os.getcwd()` because previous tests had deleted the current directory + - Solution: Wrapped `os.getcwd()` in try-except and fallback to `/tmp` + - Lesson: Be careful with directory changes in tests, always handle cleanup gracefully + +3. **Remote References in Tests** + - Problem: Tests were failing because default_base was set to `origin/main` but test repos don't have remotes + - Solution: Set `default_base` to `main` in test fixtures + - Lesson: Make config values appropriate for test environment + +4. **Uncommitted Files in Status Tests** + - Problem: Test for clean worktree was failing because `.wt.toml` was uncommitted + - Solution: Commit the config file in the manager fixture + - Lesson: Ensure test setup leaves repository in expected state + +5. **TOML Library Compatibility** + - Problem: Need to support Python 3.10 which doesn't have built-in tomllib + - Solution: Added conditional import with fallback to tomli package + - Lesson: Always consider Python version compatibility + +6. **Config Not Found in Secondary Worktrees** + - Problem: When running wt commands from a secondary worktree, it would ask to run `wt init` again because it couldn't find `.wt.toml` + - Initial Solution: Added `get_main_worktree_root()` function to find main worktree + - Better Solution: Simplified to use global config in `~/.wt.toml` (or `$WT_CONFIG/.wt.toml`) + - Rationale: Simpler design, no need to find main worktree, works the same everywhere + - Changes: + - Config now stored in one place (home directory by default) + - Removed local repo config concept + - `wt init` is now optional (just sets custom defaults) + - No need to run `wt init` per repository + - Lesson: Sometimes the simplest solution is the best - global config is easier than per-repo config for this use case + +### Test Results + +- **Total Tests**: 58 +- **Passed**: 58 +- **Coverage**: 63% +- **Key Coverage Areas**: + - git.py: 86% (core git operations well tested, including worktree detection) + - config.py: 75% (configuration management tested) + - worktree.py: 62% (worktree operations tested) + - cli.py: 54% (CLI commands tested including secondary worktree usage) + +7. **Missing Special Symbol Support in `wt run`** + - Problem: The `wt run` command didn't support the `^` (default) and `-` (previous) symbols, while `wt switch` did + - Error: Running `wt run ^ "git status"` or `wt run - "git diff"` resulted in "Error: Worktree not found" + - Solution: Added special handling for both `^` and `-` symbols in the `run` command (cli.py:379-409) to resolve them before looking up the worktree + - Implementation: + - Added check `if name == "-":` to find the previous worktree from `.wt_previous` file and resolve it to the worktree name + - Added check `elif name == "^":` to get the default worktree using `ctx.manager.get_default_worktree()` and use its name + - Tests: Added five new tests in test_cli.py: + - `test_run_command`: Tests running a command in a normal worktree + - `test_run_command_with_default_symbol`: Tests running a command using `^` symbol + - `test_run_command_with_previous_symbol`: Tests running a command using `-` symbol + - `test_run_command_no_previous_worktree`: Tests error handling when no previous worktree exists + - `test_run_command_nonexistent_worktree`: Tests error handling for non-existent worktrees + - Lesson: Always ensure consistency across commands - if a special symbol works in one command, users will expect it to work in related commands too + +### Future Improvements + +1. **Increase CLI Test Coverage**: Add more edge case tests for CLI commands +2. **Integration Tests**: Add end-to-end tests with real workflows +3. **Shell Integration Tests**: Test actual shell wrapper execution +4. **Error Message Tests**: Verify all error messages are clear and actionable +5. **Performance**: Optimize
