Marmot Interop Test Harness

Two flavours, same scenarios:

• marmot-interop.sh — interactive. Drives B/C via wn and prompts the human to perform each Amethyst-side step in the mobile UI (Identity A). Use this for final UI verification.
• marmot-interop-headless.sh — zero prompts. Drives A via the amy CLI (./gradlew :cli:installDist) and B/C via wn. Runs every scenario end-to-end and exits with a pass/fail summary. Use this for CI and for iterating on the Nostr/Marmot plumbing without needing to touch a phone.

Both harnesses validate Amethyst against whitenoise-rs (https://github.com/marmot-protocol/whitenoise-rs), the reference Rust implementation that powers the White Noise Flutter app. Every test records a pass/fail/skip result into a tab-separated log, and the summary is printed at the end of the run.

05	wn adds Amethyst to existing group	yes
06	Member removal + forward secrecy	yes

Prerequisites

On the machine that runs the harness:

• Rust 1.90+ — install via https://rustup.rs
• git, curl, jq — package manager
• ~5 GB disk for the first-run build of wn + wnd
• Public internet access (for the default relay set and fetching crates)

On the Android side:

• Amethyst installed on an emulator or a physical device
• The device must reach the same relays the harness uses (see below)

Quick start

cd tools/marmot-interop
./marmot-interop.sh

The script will, in order:

1. Verify jq, git, cargo etc. are present.
2. Clone whitenoise-rs into state/whitenoise-rs/ and build wn/wnd (release, --features cli). First build takes ~5 minutes; subsequent runs reuse the binaries.
3. Launch two wnd daemons (one for Identity B, one for Identity C).
4. Create Nostr identities for B and C, persist their npubs in state/run.env.
5. Ask you to paste your Amethyst account npub (Identity A). This is cached for subsequent runs.
6. Add the default public relays to both daemons and run a sanity check (publish a KP from B, fetch it from C).
7. Print an Amethyst setup checklist — add the same relays to Amethyst, publish a KP, verify you are logged in with A.
8. Run all 13 tests sequentially. Each test either:
   • runs wn commands fully automatically and asserts on JSON output, or
   • prints a "DO THIS IN AMETHYST" prompt and waits for you to press <Enter>, then verifies the Amethyst action via wn.
9. Stop the daemons and print a results table.

Command-line flags

--local-relays    Use ws://localhost:8080 instead of the default public relays.
                  Required if the public relays reject kinds 444/445/30443.
                  Run 'just docker-up' inside whitenoise-rs first.
--transponder     Run Test 14 (push notifications via the transponder service).
--no-build        Fail instead of rebuilding wn/wnd. Useful when iterating.
-h, --help        Show help.

Environment overrides:

WN_REPO=/some/path/whitenoise-rs   # use an existing checkout

Default relays

wss://relay.damus.io
wss://nos.lol
wss://relay.primal.net

These are known to accept kind 1059 (gift wraps) and kind 30000+ (addressable events). If the sanity check fails — meaning C cannot read the KeyPackage that B just published — the harness warns you and continues. In that case re-run with --local-relays after starting the Docker stack:

cd state/whitenoise-rs
just docker-up
cd ../..
./marmot-interop.sh --local-relays

For Amethyst with --local-relays:

• Android emulator: add ws://10.0.2.2:8080 to Settings → Relays and Settings → Key Package Relays.
• Physical device on same Wi-Fi: add ws://<laptop-LAN-ip>:8080.

How human interaction works

When the script needs you to do something in Amethyst, it prints a yellow block like this:

---- DO THIS IN AMETHYST ----
In Amethyst:
  1. Tap + -> Create Group
  2. Name: Interop-02
  3. Add member: npub1abc...
  4. Tap Create / Send Invite
-----------------------------
[Press Enter to continue]

After you press Enter the script resumes. For UI-only verifications (e.g. "does Amethyst show reaction 🌮?"), the script asks:

? Does Amethyst show the 🌮 reaction?  [p]ass / [f]ail / [s]kip:

Pick p, f, or s.

Output

• state/logs/run-<timestamp>.log — every step, assertion, and human prompt, with the exact wn stdout that was parsed.
• state/results-<timestamp>.tsv — tab-separated test_id \t status \t note lines. Easy to grep.
• state/run.env — persistent key/value state (npubs, group ids) so you can kill and resume the harness mid-run without losing context.
• Final summary table on stdout — colored per-test status and totals.

State cleanup

The harness leaves state/ on disk so daemons and identities survive across runs. To start completely fresh:

# stops daemons if still running; removes identities, groups, logs
./marmot-interop.sh --no-build   # Ctrl-C when it waits for input, then:
rm -rf state/

Published KeyPackages on public relays will remain until they expire naturally or are deleted via wn keys delete-all --confirm. Use a throwaway identity for B/C if this matters to you.

Known gaps

• Test 10 (concurrent commits) is inherently human-timing sensitive. It's a best-effort race; expect occasional flakes.
• Test 14 (push) only exercises the harness side — full end-to-end verification requires a running transponder instance and platform registrations that are out of scope here.
• The harness assumes Amethyst exposes UI affordances for add-member, remove-member, rename, promote/demote, and leave. If any of those is missing from the current build, the corresponding test will fail with a clear note rather than crash.

Files

• marmot-interop.sh — main entry point; orchestrates preflight, daemons, identities, relays, and runs the 13 tests in sequence.
• lib.sh — helpers (logging, prompts, polling, jq wrappers, result table).
• state/ — runtime directory, gitignored. Contains whitenoise-rs/ source checkout, per-daemon data/log dirs, the session run.env, logs, and results TSVs.
