Problem

The gateway client integration has zero test coverage. The 33 existing unit tests only cover signing, shared types, and backend validation — none of the GatewayClient methods (account ops, token transfers, marketplace listings) are tested.

Solution — Three Test Layers

Layer 1: Integration Tests (wiremock)

New crates/gateway-tests/ crate with 23 tests using wiremock to mock the gateway's JSON-RPC /rpc endpoint:

Credential setup (mnemonic derivation, determinism, custom account ID, invalid mnemonic)
Health check
Account methods (exists, activate, get_balance, get_token_balance)
Token methods (storage_deposit, transfer, transfer_with_memo) — tests the two-step write flow
Marketplace methods (create_listing, list_by_farmer, get_listing_count)
Error handling (RPC errors, malformed JSON, network errors, no credentials, server 500)

Runs with make test-gateway or cargo test -p gateway-tests. No network needed.

Layer 2: Gateway Smoke Tests (bash/curl)

scripts/gateway-smoke-test.sh — follows existing smoke-test.sh pattern:

Gateway health + RPC discover
Account activation (public method)
Error handling (invalid method, malformed JSON, empty body)

Runs with make gateway-smoke-test. Requires network access to gateway.

Layer 3: E2E Browser Tests (Playwright)

e2e/ directory with Playwright setup:

App loads without WASM panic
Login button visible
No RefCell borrow panic on navigation
Wallet connect with mnemonic (via TEST_MNEMONIC env var)
Navigate after connecting (RefCell regression test)
Vault save and unlock flow

Runs with make test-e2e. Requires dx serve running on :8080.

Mnemonic is provided via TEST_MNEMONIC env var — never hardcoded. For CI, use a repo secret.

New Makefile Targets

test-gateway — wiremock integration tests
gateway-smoke-test — real gateway smoke tests
e2e-install — install Playwright + Chromium
test-e2e — run E2E browser tests
test-all updated to include test-gateway

## Problem The gateway client integration has zero test coverage. The 33 existing unit tests only cover signing, shared types, and backend validation — none of the `GatewayClient` methods (account ops, token transfers, marketplace listings) are tested. ## Solution — Three Test Layers ### Layer 1: Integration Tests (wiremock) New `crates/gateway-tests/` crate with 23 tests using wiremock to mock the gateway's JSON-RPC `/rpc` endpoint: - Credential setup (mnemonic derivation, determinism, custom account ID, invalid mnemonic) - Health check - Account methods (exists, activate, get_balance, get_token_balance) - Token methods (storage_deposit, transfer, transfer_with_memo) — tests the two-step write flow - Marketplace methods (create_listing, list_by_farmer, get_listing_count) - Error handling (RPC errors, malformed JSON, network errors, no credentials, server 500) Runs with `make test-gateway` or `cargo test -p gateway-tests`. No network needed. ### Layer 2: Gateway Smoke Tests (bash/curl) `scripts/gateway-smoke-test.sh` — follows existing `smoke-test.sh` pattern: - Gateway health + RPC discover - Account activation (public method) - Error handling (invalid method, malformed JSON, empty body) Runs with `make gateway-smoke-test`.
