…wswap into e2e/hooks-store
Covers toggling Hooks on in swap settings, the nav entry appearing behind the "Trading mode" dropdown, persistence across a reload, and navigating into the Hooks-enabled swap widget. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

WalkthroughThe change adds Playwright mocks for bridge tokens, hook simulations, hook logos, and token logos. It adds E2E coverage for Hooks settings, cross-chain restrictions, custom pre-hook execution, order settlement, and activity history. ChangesHooks and cross-chain E2E coverage
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The new end-to-end tests may be nondeterministic because mock routes are not awaited, and one text selector may match multiple elements. The PR is mergeable with explicit owner awareness and follow-up to make the test setup and selectors deterministic. Sequence Diagram(s)sequenceDiagram

Covers the buy-token picker never offering another chain on the Hooks tab, a cross-chain buy token set via URL query params not being reset on Hooks (known gap, asserted with expect.soft so it doesn't hide the other passing checks), and the reset that does happen when navigating Swap -> Hooks via the in-app tab link. Adds mockBridgeSupportedTokens to stub the Bungee/Socket dest-tokens endpoint so a cross-chain buy token can be resolved without a live network call. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The URL-param reset check (targetChainId not cleared when set directly on the Hooks route) was a known-failing expect.soft in [CS-136], which still reported the whole test as failed in CI. Move it into its own [CS-136b] wrapped in test.fixme so [CS-136] stays green; un-fixme [CS-136b] once the frontend actually resets it. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Drop the fixme test for the URL-param reset gap per request. Fold its scenario back out of scope and instead tighten what [CS-136] verifies after navigating Swap -> Hooks with a cross-chain buy token: both the sell and buy token reset to the Sepolia default pair (WETH/USDC), and a real quote loads for that reset pair rather than lingering in a bridge "No routes found" state. The quote check needed an actual sell amount entered first — without one, no quote request fires and waitForQuote resolved on a technicality instead of proving anything. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The default quote fixture's raw buyAmount doesn't match mocks.usdPrices' $1-per-token default, so the reset-pair quote check rendered an absurd (~54615%) rate deviation next to the buy amount instead of a normal-looking quote. Pin a 1:1 rate via mockFixedRateQuote, same as several other tests in this file already do for their own quote checks. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Extend the final check beyond "a quote loaded" to confirm the reset Sepolia WETH/USDC pair reaches a genuinely tradeable state: the partial/full approval selector renders (WETH allowance is unset for this wallet, same as every other test in this describe block) and the approve/swap button is enabled. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Drop the artificial 1:1 mockFixedRateQuote override. The default quote fixture's WETH/USDC rate is a real recorded snapshot (~546.99 USDC/WETH) — the absurd price-impact percentage was caused by mocks.usdPrices' unrelated $1-per-token default not matching that real rate, not by the rate itself. Match usdPrices to the real rate instead of replacing it. Also move the sell-amount entry earlier, onto the Swap tab before switching to Hooks, so the test covers navigating away from a genuinely active, quoted bridge trade. Confirmed empirically that the typed amount survives the tab switch (only the currencies reset), so the reset pair's quote recalculates automatically without re-entering anything — assert on that real recalculated value (547.1548 USDC, 0.03% price impact) plus a sane, non-bridge price impact. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Covers adding a pre-hook via the built-in "Build your own hook" Hook Store dapp (BUILD_CUSTOM_HOOK, non-iframe — directly calls context.addHook, no extra fixture server needed), placing a swap order with it attached, and verifying the hook round-trips correctly: the Account modal's activity details decode the settled order's appData (mockOrderPosting already echoes it back as fullAppData) and render the "Hooks" / "PRE" summary that OrderHooksDetails produces. The hook's calldata encodes a real ERC20 approve() call against the CoW Protocol VaultRelayer, representing the ticket's "token approval" example without needing it to ever actually execute on a real chain.

…ogos
Four fixes based on review feedback:
- Enable Hooks via the Settings toggle UI first (same mechanic as
[CS-129]), then navigate to the Hooks tab through the nav link,
instead of a direct URL shortcut that skipped the toggle entirely.
- Mock the Tenderly bundle-simulation endpoint (never mocked before —
a real POST to {BFF_BASE_URL}/{chainId}/simulation/simulateBundle)
so the confirmation screen's hook row shows a genuine "Simulation
successful" green light instead of silently never resolving.
- Mock the token-logo CDN (files.cow.fi/token-lists/images), which
403s for this suite's Sepolia test-token addresses (verified
directly) and was silently falling back to a single-letter avatar
instead of a real icon.
- Drop the artificial 1:1 quote rate in favor of matching usdPrices to
the default fixture's real recorded WETH/USDC rate, same fix as
[CS-136].

… [CS-131] mockTokenLogos was fulfilling the 403'ing token-logo CDN with a fake "successful" transparent PNG, which bypasses TokenLogo's onError-based fallback (SingleLetterLogo) and renders as a plain black circle instead. Mock a deterministic 404 instead so the app's real fallback UI shows. The hook's BUILD_CUSTOM_HOOK logo was a live, unmocked raw.githubusercontent.com fetch with no onError fallback in HookItem, so any network hiccup left a bare placeholder box. Add mockHookLogo, serving the same build.png already checked into the frontend, removing that live network dependency. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…31/136 @smoke The 404-based mockTokenLogos fix only reached TokenLogo's letter-avatar fallback, not the actual brand icon the ticket expects. Redirect each Sepolia test-token's logo request to its real mainnet counterpart's icon via route.fetch()'s URL override, so the real WETH/USDC images render on both the swap and hooks tabs. Verified visually via screenshot. Also add @smoke to CS-129, CS-131, and CS-136. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

1523-1528: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick winMerge into the persisted user state instead of replacing it.
localStorage.setItemwrites a fresh object that contains onlyhooksEnabled. This discards every other persistedstate.userfield written earlier in the test, for example slippage and recipient preferences. The test currently passes because the reducer falls back to defaults for missing fields. A future assertion that depends on other persisted user state would break in a way that is hard to diagnose.♻️ Proposed change
await swapPage.page.evaluate(() => - localStorage.setItem('redux_localstorage_simple_user', JSON.stringify({ hooksEnabled: true })), + localStorage.setItem( + 'redux_localstorage_simple_user', + JSON.stringify({ + ...JSON.parse(localStorage.getItem('redux_localstorage_simple_user') || '{}'), + hooksEnabled: true, + }), + ), )🤖 Prompt for AI Agents

- Around line 7-10: Replace the address normalization in the mock token logo
lookup with getAddressKey from `@cowprotocol/cow-sdk`, including the match[1]
conversion and REAL_MAINNET_ADDRESS keys; preserve the existing mapping and
lookup behavior while removing all toLowerCase-based normalization.
In `@apps/cowswap-e2e-tests/src/tests/market-orders.spec.ts`:
- Around line 1660-1662: Update the getByText call in the confirmationModal
interaction to use an exact rendered-text pattern for the PRE label and its
count, avoiding substring matches while preserving the click target.

- mockTokenLogos: normalize addresses with getAddressKey (@cowprotocol/cow-sdk) instead of toLowerCase(), per repo coding guidelines. - Await context.route() in all four new mock helpers (mockTokenLogos, mockHookLogo, mockHooksSimulation, mockBridgeSupportedTokens) and their call sites, so a request fired right after setup can't race past registration. - CS-136: merge into the persisted redux_localstorage_simple_user state instead of overwriting it, so earlier-written user fields survive the reload. - CS-131: tighten the "PRE" tag matcher to the full rendered pattern instead of a bare substring, avoiding a possible strict-mode match. - Move the repeated generated-class "Trading mode" dropdown locator out of the three tests and into SwapPage as a shared, named locator.
