# 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 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.
