Add comprehensive test coverage for all wt scripts using BATS
(Bash Automated Testing System) with bats-assert and bats-support
as git submodules.
Test structure:
- test/unit/ — library function tests (wt-common, wt-context, wt-context-setup)
- test/integration/ — per-command tests (wt-add, wt-cd, wt-context, wt-list,
wt-metadata-export, wt-metadata-import, wt-remove, wt-switch)
- test/e2e/ — full workflow tests (lifecycle, multi-worktree, context switching)
- test/test_helper/ — shared setup, teardown, and assertion helpers
- test/README.md — test architecture docs and guide for adding new tests
Source fixes applied during test development:
- wt-list: add usage() function, -h/--help flag, use pwd -P for consistent
path comparison with git worktree list output
- wt-common: refactor config loading to source wt-context library directly
instead of custom parsing; use pwd -P in wt_get_linked_worktree for macOS
symlink consistency (/var -> /private/var)
- wt-add: improve install_bazel_symlinks_for_worktree doc comment
Also update CONTRIBUTING.md to reference the new test suite.

Summary
Initial attempt to add test coverage for the wt worktree toolkit using BATS (Bash Automated Testing System).
This PR adds 167 tests across three layers:
Unit tests (test/unit/) - Direct function-level tests for library code (wt-common, wt-context, wt-context-setup). Tests output helpers, git helpers, path expansion, metadata detection, context CRUD operations, and config loading.
Integration tests (test/integration/) - Per-command tests for each bin/wt-* script (wt-add, wt-cd, wt-context, wt-list, wt-metadata-export, wt-metadata-import, wt-remove, wt-switch). Each test creates isolated git repos in temp directories and validates real git operations, file system state, symlink behavior, error handling, and safety checks.
E2E tests (test/e2e/) - Full workflow tests covering complete worktree lifecycle (create, switch, work, remove), multi-worktree management, new branch creation with -b, context switching across repositories, dirty worktree handling, and symlink consistency across repeated operations.
