Development and testing

Local editor environment #

Run these commands in the openeditorcode repository, not the website. Bun >=1.3.0 is documented; CI uses 1.3.14. Keep the OpenTUI preload included in scripts.

bun install --frozen-lockfile
bun run dev

bun run typecheck
bun run test
bun run build

What existing tests verify #

• Filesystem/documents: UTF-8, binaries, limits, paths, exclusive creation, external changes, CRLF and concurrent opening.
• TUI: layout, focus, palette, tabs, search, manual, preview and Git navigation through a test renderer.
• Git: real-repository fixtures, stage/unstage, commits, workspace, pagination, merges, branches and historical mutation blocking.
• Configuration/CLI/launcher: defaults, migration, backup, arguments and updates using mocked dependencies; the Bash installer has offline failure and rollback tests.

CI and coverage scope #

The CI matrix covers Ubuntu and Windows: frozen lock, preflight, typecheck, coverage, build and smoke. Configured thresholds are 50% lines and 20% functions; TSX and clipboard are excluded from coverage.

Typecheck includes src, tests and build.ts, with skipLibCheck. One smoke checks MZ/ELF format; another reaches the first frame. The npm smoke uses --omit=optional to verify shims/notices, not installed binary startup.

Cases needing more evidence #

The test renderer cannot distinguish every terminal modifier. Not every clipboard tool, graphics protocol or Vim movement is certified. SVG, filters, preview saving and document concurrency have specific regressions; publication checks must be confirmed by workflow, not inferred from this catalog.
