 The test framework itself — the `test()` / `run()` / `app.*` API that the tests
 import from `test-framework/framework.mjs` — comes from the
 [**`logos-co/logos-qt-mcp`**](https://github.com/logos-co/logos-qt-mcp) repo.

+# AMM UI tests
+
+UI-driven tests for the AMM app. `swap.mjs` drives the running app through the
+QML inspector (framework from
+[`logos-co/logos-qt-mcp`](https://github.com/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`):
+
+```bash
+# 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):
+
+```bash
+nix build .#integration-test -L
+```
+
+## Notes
+
+- **Wallet password.** The isolated wallet is restored with password `test`
+  (`TEST_WALLET_PASSWORD`). If the UI shows the **Connect** modal instead of
+  auto-opening, unlock with `test`.
+- **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.
