Inline comments:
In `@apps/cowswap-e2e-tests/src/support/mockEthFlowTransaction.test.ts`:
- Around line 143-147: Update registerFakeOtherMock to compare target and t
using areAddressesEqual from `@cowprotocol/cow-sdk` instead of toLowerCase() and
===, preserving the existing call-data match and resolver behavior.
In `@apps/cowswap-e2e-tests/src/support/mockWrapTransaction.ts`:
- Around line 49-55: Update the eth_sendTransaction stub in wrapContractCall to
accept only calldata beginning with the deposit() function selector and reject
subsequent sends after the first accepted transaction, matching the guard
behavior in mockUnwrapTransaction. Preserve the existing sentValue, balance
update, and FAKE_WRAP_TX_HASH behavior for the single valid send.
In `@apps/cowswap-e2e-tests/src/tests/market-orders.spec.ts`:
- Around line 131-135: Update the assertions in the order progress flow around
soldAmountRow and receivedAmountRow to poll readTitledAmount until the displayed
values match postedOrder.sellAmount and postedOrder.buyAmount, respectively.
Preserve the existing row locators and expected zero fallback while waiting for
the slower order-details data to update.
- Around line 850-856: Replace the USDC PermitInfo fixture key’s direct
toLowerCase normalization with getAddressKey from `@cowprotocol/cow-sdk`,
preserving the existing key and payload behavior in the context.route handler.

## What changed - Adds a new `apps/cowswap-e2e-tests` Playwright + Synpress suite: project config, a mock-wallet fixture (viem-backed, instant signing, no MetaMask extension), a per-worker RPC proxy, and page objects for the Swap/Limit/TWAP/Account/Trade flows. - Mocks for `api.cow.fi`/`barn.api.cow.fi` (orders, quotes, trades, appData, etc., recorded from the live barn API), balances/allowances, node RPC calls, LaunchDarkly flags, and the Safe SDK. - Two new CI workflows: `e2e-pw-smoke` (runs `@smoke`-tagged tests on PRs touching frontend/e2e/libs code) and `e2e-pw-nightly` (full suite, 4-way sharded, cron + manual dispatch) — replacing the previously disabled Cypress job in `ci.yml`. `.mergify.yml`'s merge gate switches from `check-success=Cypress` to `check-success=smoke`. - Drops the old `cowswap-frontend-e2e` (Cypress) app from `enabledApps` and its now-unused deps/patches. - `AGENTS.md`/`README.md` docs for the new suite (architecture, mocking mechanics, known flakiness and how it was diagnosed). - No `cowswap-frontend` production code changes. ## Why - Replaces the disabled Cypress e2e setup with a faster, mock-first Playwright suite that doesn't need a live testnet/relayer for most scenarios, and wires it into CI as a PR-gating smoke check plus a nightly full run. ## QA Testing Reviewer note: - Pure test-infrastructure change with no production code diff — nothing to browser-test here. The suite's actual test coverage is added in the stacked [PR #8038](#8038) (market orders) and [PR #8039](#8039) (cross-chain). Developer verification: - `smoke` CI check passed on this PR (no specs exist yet at this point in the stack, so it currently confirms the pipeline wiring itself). ## Preview URLs | Surface | URL | | --- | --- | | swap-dev - branch preview URL | https://swap-dev-git-e2e-tests-p1-cowswap-dev.vercel.app | | explorer-dev - branch preview URL | https://explorer-dev-git-e2e-tests-p1-cowswap-dev.vercel.app | | widget-configurator - branch preview URL | https://widget-configurator-git-e2e-tests-p1-cowswap-dev.vercel.app | | storybook - branch preview URL | https://storybook-git-e2e-tests-p1-cowswap-dev.vercel.app | | cowfi - branch preview URL | https://cowfi-git-e2e-tests-p1-cowswap.vercel.app | --------- Co-authored-by: cowswap-release-sync[bot] <274575433+cowswap-release-sync[bot]@users.noreply.github.com> Co-authored-by: Elena <70885163+elena-zh@users.noreply.github.com> Co-authored-by: elena-zh <elena@cow.fi> Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com>

## What changed
- Adds a `window.__COWSWAP_E2E__` runtime flag: under it, GTM analytics
and the LaunchDarkly provider are swapped for no-ops, feature flags are
read from `window.__COWSWAP_E2E_FEATURE_FLAGS__` instead, and several
update-interval consts (order-book polling, allowances, priority tokens,
limit/expired-order checks) are compressed to ~2s via a new
`getUpdaterInterval()` helper in `common-const`.
- Bypasses the NEAR Intents deposit-address signature check only when
`NODE_ENV !== 'production'` **and** the e2e flag is set — dead code in
every deployed build (prod, staging, and Vercel previews all run the
production webpack build), needed because e2e's mocked NEAR
quote/attestation fixtures can't carry a real signature.
- Adds stable locator hooks (`data-testid`/`id`/`className`) to several
components so tests don't rely on style-derived selectors:
`CurrencyInputPanel` fiat amount, `PriceImpactIndicator`,
`TradeDetailsAccordion`, `EthFlowStepper`/`Step`, `OrdersTable`,
`AccountDetails` activity list, approve-mode `Toggle`,
`CollapsibleBridgeRoute`, `SnackbarPopup`,
`ConfirmDetailsItem`/`ReviewOrderModalAmountRow`,
`TradeFormBlankButton`.
- Fixes 3 real bugs surfaced while building the e2e suite:
- `HydrateAtom` wrote to its atom during render, which could update an
already-mounted sibling mid-render (React warns "Cannot update a
component while rendering a different component") and the write could be
silently dropped — observed as the sell token intermittently reverting
to "Select a token". Moved the write into `useLayoutEffect`.
- `OrdersFromApiUpdater` and `PendingOrdersUpdater` both poll and write
order status independently. If `OrdersFromApiUpdater` wrote `FULFILLED`
first, the order left `PendingOrdersUpdater`'s locally-tracked pending
bucket before it could detect the transition, and the "Transaction
completed" surplus modal never appeared. `OrdersFromApiUpdater` now
detects the pending→fulfilled transition itself and queues the modal.
- `useSetupTradeAmountsFromUrl`'s "has an amount ever been set" ref was
overwritten every render instead of staying sticky, so switching the
buy/sell currency (which transiently reads the amount back as `null` for
one render) could stomp a real typed sell amount with the "1 unit"
default — the flaky `enterSellAmount('1000')` behavior tracked as CS-59.
- `getTokenFromMapping` now normalizes addresses with `getAddressKey`
from `@cowprotocol/cow-sdk` instead of viem's `getAddress`, per the
repo's address-handling convention.
## Why
- The e2e suite (scaffolded in [PR
#8035](#8035), exercised in
[#8038](https://github.com/cowprotocol/cowswap/pull/8038)/[#8039](https://github.com/cowprotocol/cowswap/pull/8039))
needs stable selectors, fast polling against mocked endpoints, and a way
to disable third-party SDKs (GTM/LaunchDarkly) that have no test-safe
configuration — building it surfaced the three state-timing bugs above.
## QA Testing
Preview URL QA:
- Sell-amount stability across a currency switch (CS-59 regression): on
the swap-dev preview, type a sell amount, then change the sell or buy
token — the typed amount should be preserved, not reset to the "1 unit"
default.
Developer verification:
- `smoke` CI check passed on this PR.
- Targeted unit tests cover the surplus-modal pending→fulfilled
transition (`OrdersFromApiUpdater.test.ts`) and the URL-driven amount
defaulting (`useSetupTradeAmountsFromUrl.test.ts`,
`useNavigateOnCurrencySelection.test.tsx`).
Reviewer note:
- The `OrdersFromApiUpdater`/`PendingOrdersUpdater` race only manifests
when polling is fast relative to order fill time (production's default
30s order-book poll vs. e2e's compressed ~2s), so it isn't reliably
reproducible through a preview URL — coverage relies on the added unit
test.
- The `window.__COWSWAP_E2E__` branches and the NEAR Intents signature
bypass are inert in any real deployment (guarded by `NODE_ENV !==
'production'`, which every deployed build fails) — worth confirming that
guard specifically since it's the one security-relevant change in this
PR.
