Test and benchmark Sandwalk changes the way CI does: which checks to run per change type (web unit + coverage gate, CLI pytest/ruff/mypy, Playwright grid and terminal e2e, perf bench with baseline/compare, live multi-agent grid bench), how to read the perf counters, and how to add tests. Use before committing, when asked to test/verify/benchmark, when CI fails, or when adding a spec, a perf counter, or a benchmark.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Sandwalk testing

## Which checks for which change

| You changed | Run | Time |
|-------------|-----|------|
| Anything, before commit | `scripts/verify.sh` (= required CI gate) | ~2 min |
| `apps/local-web/src` | `scripts/verify.sh web` | ~40 s |
| `cli/src` | `scripts/verify.sh cli` | ~50 s |
| Split grid, terminals, sidebar/strip, PTY, tiling | `scripts/verify.sh` **and** `scripts/verify.sh e2e` | +30 s |
| Perf-sensitive UI (rendering, scroll, terminal layer, stores) | e2e + `pnpm e2e:bench` vs. a baseline (below) | +1 min |
| Agent runtime, streaming, LLM params, API latency | live bench (below; costs tokens) | +1–5 min |

`verify.sh` stops at the first failing step. Fix, re-run only that target, then
run the full script once before committing. CI additionally runs the Mac app
tests (`pnpm test:mac`, needs Xcode).

## Unit tests

- Web (Vitest, jsdom): `pnpm --filter @sandwalk/agent-local-web test` —
  colocated `*.test.ts(x)`. Coverage gate in `apps/local-web/vitest.config.ts`
  is per-glob: `src/lib/**` 80 %, hooks 25 %, app model 40 %, terminal layer
  10 % (floors — raise them when you add tests, never lower).

How to install

The exact contents, by fingerprint
mdr add fastfold-ai/sandwalk/sandwalk-testing@sha256:f2381aeafeb8f302

The line at the top of this page pins the label git:20260929.6902891, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
