UI-driven tests for the AMM app. swap.mjs drives the running app through the QML inspector (framework from logos-co/logos-qt-mcp): it selects two tokens, enters an amount, submits a swap, and verifies the pool reserves changed on-chain.

Isolation

Test runs never touch your personal setup. Everything test-related lives under apps/amm/tests/testnet/ and is git-ignored:

Concern	Test (isolated)	Your local dev
Wallet home	`apps/amm/tests/testnet/.wallet/`	`~/.lee/wallet/`
Token config	`apps/amm/tests/testnet/amm-tokens.json`	`apps/amm/amm-tokens.json`

testnet/setup-amm-testnet.sh bootstraps an isolated wallet from a fixed mnemonic (test test … junk) so the token/holding account ids are deterministic and reproducible across machines, then deploys the programs, creates a seeded pool, and writes the test token config.

Full isolated run

From the repo root, with wallet / spel / cargo / nix on PATH, a local sequencer running, and the guest binaries built (make build-programs):

# 0. Once: build the JS test framework (symlinked where swap.mjs expects it)
nix build .#test-framework -o apps/amm/result-mcp

# 1. Bootstrap the isolated wallet + deploy programs + create the pool.
#    Writes apps/amm/tests/testnet/{.wallet, amm-tokens.json}. Nothing else is touched.
TEST_SEQUENCER_ADDR=http://127.0.0.1:3040 apps/amm/tests/testnet/setup-amm-testnet.sh

# 2. Terminal 1 — launch the UI against ONLY the isolated wallet + test tokens.
LEE_WALLET_HOME_DIR=$(pwd)/apps/amm/tests/testnet/.wallet \
  AMM_PROGRAM_BIN=$(pwd)/programs/amm/methods/guest/target/riscv32im-risc0-zkvm-elf/docker/amm.bin \
  TOKENS_CONFIG=$(pwd)/apps/amm/tests/testnet/amm-tokens.json \
  nix run .#amm-ui

# 3. Terminal 2 — drive the swap test; watch it click through the live UI.
node apps/amm/tests/swap.mjs

Headless CI variant (no window, launches the app itself, pass/fail only):

nix build .#integration-test -L

Notes

Wallet password. The wallet's key storage is encrypted with a password — the one you enter to unlock it (the UI's Connect modal) so the app can sign transactions. First-time setup reads a throwaway password (the script feeds it via stdin, so it doesn't block), then restore-keys rebuilds the wallet from the test mnemonic and sets the real password to TEST_WALLET_PASSWORD (default test). So unlock the UI with test. Prefer no password? Run with TEST_WALLET_PASSWORD="" and unlock with an empty password.
Re-bootstrap. FORCE_BOOTSTRAP=1 apps/amm/tests/testnet/setup-amm-testnet.sh re-restores the isolated .wallet (rewrites only that directory).
Overrides. TEST_WALLET_HOME, TEST_MNEMONIC, TEST_WALLET_PASSWORD, TEST_WALLET_DEPTH, TEST_SEQUENCER_ADDR — see the script header.
Framework location. swap.mjs loads ../result-mcp by default; override with LOGOS_QT_MCP=/abs/path/to/result-mcp.
Artifacts. On failure swap.mjs prints the SwapCard state and saves apps/amm/tests/swap-*.png (git-ignored) for inspection.
