fix(e2e): column-visibility coverage + decouple testPrefix from auth (#1966, #1969)

[steilerDev]

Summary

• E2E coverage: ReportContentEditor column-visibility toggles #1966 — Added Scenario 24 to reportWizardEditableContent.spec.ts: asserts all 7 column checkboxes present (budget-overview), count = component-defined column count, toggling fires no PATCH /api/users/me/preferences, runs at all three viewport projects
• E2E fixtures: decouple testPrefix from authenticatedPage in e2e/fixtures/auth.ts #1969 — Removed unused authenticatedPage dependency from testPrefix fixture in e2e/fixtures/auth.ts; all 69 testPrefix consumers also request auth explicitly via page (grep-audited)

Fixes #1966
Fixes #1969

Test plan

• E2E shards green (Scenario 24 coverage verified in shard containing reportWizardEditableContent.spec.ts)
• Shard redistribution triaged if any shard reddens

AC4 testPrefix consumer audit

All 69 spec files using testPrefix also request page or authenticatedPage explicitly — no test silently gains or loses an auth context.

VERDICT: CHANGES_REQUIRED

Reviewed both changed files against the Wiki Architecture page conventions, the e2e/ fixture contract, and the component source (client/src/components/reports/ReportContentEditor.tsx). No production code, schema, API contract, or shared types are touched — so no Schema.md / API-Contract.md / ADR updates are owed by this PR, and there is nothing here that diverges from documented architecture.

#1969 is sound. I independently re-ran the consumer audit: 72 files under e2e/tests/ reference testPrefix, and zero of them request testPrefix without also destructuring page or authenticatedPage. Since the desktop/tablet/mobile projects all set storageState: 'test-results/.auth/admin.json' at the project level, page is authenticated independently of the fixture, so dropping the dependency cannot silently strip auth from any test. The change is a correct decoupling. (The PR body says 69 consumers, I count 72 — the delta is docstring mentions, immaterial.)

#1966 has a critical defect that makes AC3 assert nothing, plus an unmet AC4. Details below.

---

CRITICAL — AC3 is vacuous: ${API} interpolates an object, so the route never matches

e2e/tests/budget/reportWizardEditableContent.spec.ts:2336

await page.route(`${API}/users/me/preferences`, (route) => {

API (e2e/fixtures/testData.ts:39) is an object literal, not a string. This template interpolates to the literal glob pattern:

[object Object]/users/me/preferences

which can never match any request. prefPatches is therefore unconditionally empty, and expect(prefPatches).toHaveLength(0) passes forever — including in the exact scenario AC3 exists to catch. If someone later wires hiddenColumns through to preferencesApi.updatePreference(), this test stays green.

This is the "assertion that passes on nothing" class of defect: the guard is a negative assertion, so a broken matcher is indistinguishable from success. Worth noting the same file already does this correctly twice — lines 969 and 998 use `**${API.paperlessStatus}` / `**${API.paperlessDocuments}` (property access, ** prefix). The new line follows neither half of the convention.

Fix: add the endpoint to the API map and use the file's existing pattern.

In e2e/fixtures/testData.ts, alongside profile: '/api/users/me':

  preferences: '/api/users/me/preferences',

then:

await page.route(`**${API.preferences}`, (route) => {

Please also confirm the fix is real rather than assumed — temporarily assert toHaveLength(1) after a page.request.patch('/api/users/me/preferences', …), or log the captured URLs once, so the matcher is proven to fire before you invert it back to 0. A negative assertion is only worth its matcher.

---

HIGH — AC4 is not met: the test is desktop-only, and the docstring claims the opposite

The tablet and mobile projects are gated by grep: /@responsive/ (e2e/playwright.config.ts:91,100). Scenario 24 carries no tag — the six responsive tests already in this file each pass { tag: '@responsive' } (lines 1133, 1208, 1547, 1813, 2038). So Scenario 24 runs on desktop only, and AC4 ("runs at all three configured viewports") is unsatisfied.

The Scenario 24 docstring states the reverse, and goes further:

AC4: coverage runs at all three configured viewports (desktop / tablet / mobile) … the mobile path is exercised by the mobile-viewport project.

That is doubly incorrect, and the second half matters because naively adding the tag will make the test fail at mobile. Both layouts are always in the DOM and CSS-gated (ReportContentEditor.module.css:286-292):

@media (max-width: 767px) {
  .table { display: none; }
  .mobileCardList { display: flex; }
}

At the iPhone 13 viewport (390px) the <table> is display: none, which removes it from the accessibility tree, so getByRole('columnheader', { name: 'Vendor' }) resolves to 0 elements regardless of toggle state. toHaveCount(0) would pass vacuously and toHaveCount(1) would fail. Tablet (iPad gen 7, 810px) is above the breakpoint and would use the table path fine. Scenario 1b in this same file already documents this dual-layout behavior — it is the established constraint here.

Pick one, explicitly:

• (a) Add { tag: '@responsive' } and make the column-removal assertion layout-aware — at mobile, assert the card caption (content.labels.vendor inside .mobileCardRow) disappears instead of the columnheader. The toggle-group assertions (AC1/AC2) are layout-independent and can stay shared.
• (b) Leave it desktop-only and correct the docstring to say so, then raise the mobile-card gap with the product-owner rather than describing coverage that does not exist.

I have no preference between them on architecture grounds — but the docstring must match what the runner actually executes. A docstring asserting coverage the config excludes is worse than no docstring, because it stops the next person from looking.

---

HIGH — lint is not clean: this PR introduces an ESLint error

npx eslint e2e/fixtures/auth.ts on this branch:

28:12  error  Unexpected empty object pattern  no-empty-pattern

CLAUDE.md's Local Validation Policy requires npm run lint to report zero warnings or errors before handback. CI's static-analysis job runs npm audit signatures, typecheck, and Stylelint but not ESLint, so this will not be caught by the gate — which is precisely why the local policy exists.

The empty pattern is genuinely required: Playwright derives a fixture's dependency list by parsing the destructuring pattern of the first parameter, and rejects a non-destructured argument, so {} is the only way to declare zero dependencies. Suppress it narrowly with the reason attached:

  testPrefix: [
    // eslint-disable-next-line no-empty-pattern -- Playwright infers fixture deps from this
    // destructuring pattern; `{}` is the supported way to declare none.
    async ({}, use, testInfo: TestInfo) => {

---

MEDIUM — the test name claims two behaviors it never asserts

'Column toggles show/hide <th> and <td> cells, reset on remount, and never write preferences'

The body asserts neither <td> cells (only getByRole('columnheader'), i.e. <th>) nor reset on remount (there is no navigation away from and back to step 5, and no other remount trigger). Neither is required by AC1-AC4, so the cheap fix is to trim the title to what it does — e.g. 'Column toggles hide the column header and never write preferences'. A title naming uncovered behavior is a coverage illusion for the next reader; if the remount-reset behavior is worth guarding, add the step-4-and-back round trip and assert all seven checkboxes return to checked.

---

Informational (non-blocking)

• OVERVIEW_COLUMN_COUNT guard is weaker than its comment claims. The comment says a future column addition "fails this test instead of silently going uncovered" — true only for someone who adds a column to the component without touching this local array. Since OVERVIEW_COLUMNS is a hand-copied duplicate of the component's list, a developer updating both keeps it green. Still the right call for E2E (importing client internals into a spec is worse), but consider softening the comment so it does not over-promise.
• Label strings verified correct. All seven hardcoded labels match sourceReports.table.* in client/src/i18n/en/budget.json (vendor/invoiceNumber/date/status/invoiceAmount/allocatedAmount/usage → Vendor/Invoice No./Date/Status/Invoice Amount/Allocated Amount/Usage), and aria-label matches sourceReports.editable.columnVisibilityLabel = Show/hide columns. The content.isOverview 7-vs-6 claim also checks out against the column-list construction at ReportContentEditor.tsx:315-322.
• Conditional-rendering claim verified. ReportContentEditor.tsx:235 is {show('vendor') && <th>…}, so the element really is removed rather than CSS-hidden — the toHaveCount(0) approach is correct for the desktop path.

---

The two blocking items are the ${API} matcher (CRITICAL) and the AC4 / docstring mismatch (HIGH); the lint error is a one-line fix. Everything else is verified good, and #1969 needs no changes. Happy to re-review once the route pattern is proven to fire.

VERDICT: CHANGES_REQUIRED

Round-2 re-review of 9e4b0e57. Three of the four round-1 findings are correctly and completely fixed. One blocking gap remains — and it is one I got wrong in round 1, so let me correct myself first.

---

Correction to my round-1 review (my error)

In round 1 I classified the misleading test title as MEDIUM and wrote: "Neither [<td> cells nor remount reset] is required by AC1-AC4, so the cheap fix is to trim the title." That was wrong. #1966 AC1 reads:

unticks one column; asserts the corresponding <th> and every matching <td> are absent from the DOM; re-ticks it; asserts both return.

The <td> assertion is explicitly required (bolded in the AC itself). Trimming the title made the title honest, but it resolved the finding in the direction that drops a required assertion rather than adding it. "Reset on remount" was correctly dropped — that one really is not in any AC. My apologies for sending you down the wrong path on the other half.

BLOCKING — AC1: the <td> half of the show/hide assertion is still missing

e2e/tests/budget/reportWizardEditableContent.spec.ts:2360-2374 asserts only getByRole('columnheader'). The component removes the body cell on the same condition (ReportContentEditor.tsx:251 → {show('vendor') && <td>{row.vendor}</td>}), so a regression that kept the header logic but broke the body logic (or vice versa) passes today.

Fix spec — add a cell locator alongside the existing header locator. Seeded vendor name is ${testPrefix} Toggle Vendor, one row is seeded, and there is no text-transform on .table td (verified at ReportContentEditor.module.css:149-153), so the accessible name is the raw vendor string:

const vendorHeader = page.getByRole('columnheader', { name: 'Vendor', exact: true });
const vendorCells = page.getByRole('cell', { name: `${testPrefix} Toggle Vendor`, exact: true });

// baseline (doubles as the locator's own positive control — same discipline as the route guard)
await expect(vendorHeader).toHaveCount(1);
await expect(vendorCells).toHaveCount(1);

await columnGroup.getByLabel('Vendor').uncheck();
await expect(vendorHeader).toHaveCount(0);
await expect(vendorCells).toHaveCount(0);   // AC1: "and every matching <td>"

await columnGroup.getByLabel('Vendor').check();
await expect(vendorHeader).toHaveCount(1);
await expect(vendorCells).toHaveCount(1);   // AC1: "asserts both return"

role="cell" maps to <td> only, and the .mobileCardList is display: none at desktop (:279), so the card-layout copy of the vendor value is out of the accessibility tree and cannot inflate the count. Please assert the baseline toHaveCount(1) before unchecking rather than only after re-checking — a toHaveCount(0) against a locator that never resolves is the same vacuous-negative trap as the round-1 ${API} bug.

Then extend the title to match, e.g. 'Column toggles show/hide column headers and cells (desktop) and never write to /api/users/me/preferences'.

---

Round-1 findings verified fixed

1. CRITICAL — AC3 route matcher: fixed, and the positive control is sound. I traced the ordering explicitly: the page.route handler runs in the Node process and pushes to prefPatches before calling route.continue(), so the in-page await fetch(...) cannot resolve until after the push has happened. expect(prefPatches).toHaveLength(1) is therefore deterministic, not racy. '**/api/users/me/preferences' matches the full URL (** spans http://host:port), and the method() === 'PATCH' filter targets the real persistence call — preferencesApi.ts:19 is the only writer and it is a PATCH to exactly that path. Resetting with prefPatches.length = 0 before the toggles is right.

Worth recording why this instrument was the correct choice: page.evaluate(fetch) issues the request from the browser context, which page.route intercepts. page.request.patch() would have gone through APIRequestContext, which page.route does not intercept — the positive control would have failed and sent you chasing a phantom. Good call.

2. HIGH — ESLint no-empty-pattern: fixed and verified live. npx eslint e2e/fixtures/auth.ts e2e/tests/budget/reportWizardEditableContent.spec.ts --max-warnings=0 is clean on this branch, and --report-unused-disable-directives reports nothing — so the directive is actually suppressing a real error, not dead weight. The rationale in the comment is accurate (Playwright parses the destructuring pattern to build the fixture dependency graph and rejects a non-destructured first parameter, so {} is the only way to declare zero deps).

For the record, in case this reads as a conflict with #1969's "Do not resolve this by renaming _ap or adding an eslint suppression": it isn't. The fixture-graph edge — the thing that issue is about — was genuinely removed. The suppression is a downstream consequence of removing it, not a substitute for removing it. AC1 of #1969 is satisfied.

3. HIGH — AC4 docstring: fixed. The new text is factually correct: no @responsive tag ⇒ desktop-only, and ReportContentEditor.module.css:286-289 is indeed @media (max-width: 767px) { .table { display: none } }, which drops the table from the accessibility tree at the 390px mobile project. AC4 permits the documented-exclusion route ("a code comment in the spec states which viewports are excluded and why"), so this satisfies it. See the note below on one sentence in it.

---

Non-blocking (address if convenient; not gating)

• MEDIUM — the path is hardcoded three times instead of going into the API map. My round-1 fix spec asked for preferences: '/api/users/me/preferences' in e2e/fixtures/testData.ts and `**${API.preferences}` at the call site; the shipped fix hardcodes the literal in the route glob, again in the page.evaluate fetch, and again in two assertion messages. The glob is correct and now provably fires, so this is style — but note the memory entry this same PR adds states "The repo convention is `**${API.<key>}` (property access + ** prefix)", so the code and the documented convention now disagree with each other. Either follow the convention or soften the memory note.

• LOW — one docstring sentence overstates neighbouring coverage. "The mobile card layout is tested in other scenarios that carry @responsive" is true of the layout in general (Scenario 1b), but no scenario covers column toggling at mobile. And the mobile path is not toggle-free: ReportContentEditor.tsx:338-410 gates every card row on the same show() predicate, so AC4's suggested rationale ("the mobile card list exposes no column toggles") does not actually hold for this component. Suggest naming the gap precisely — "the mobile card layout's toggle behaviour is not covered; the exclusion is a limitation of the columnheader locator, not an absence of toggles" — and filing a follow-up for .mobileCardRow caption assertions under @responsive. Not a blocker: AC4 asks for an explicit statement, and you have one.

• INFORMATIONAL — E2E fixtures: decouple testPrefix from authenticatedPage in e2e/fixtures/auth.ts #1969 AC2 has a premise error; flagging for product-owner, no action for you. AC2 asks for "a test that reads testPrefix in two different tests in the same file and confirms the values differ." That is unsatisfiable by construction: the value is E2E-<3-char-project><workerIndex>, so two tests in the same file running on the same worker get identical values. Despite { scope: 'test' }, the value is worker-scoped in substance. The uniqueness guarantee that actually exists (and that AC2 presumably means to protect) is across workers and projects, which is what prevents shared-DB collisions. @product-owner — please amend the AC text rather than have anyone design around it; the fixture's behaviour is unchanged by this PR and is correct. AC3's literal wording ("a spec that uses testPrefix and does not use authenticatedPage") is satisfied by Scenario 24.

• Merge precondition, not a code change: AC5 on both issues is still open. Both E2E coverage: ReportContentEditor column-visibility toggles #1966 AC5 and E2E fixtures: decouple testPrefix from authenticatedPage in e2e/fixtures/auth.ts #1969 AC5 require the full E2E suite result to be reported and any red shard triaged as caused-by-this-change vs. pre-existing-latent, with evidence, in a PR comment — explicitly "re-running until green does not satisfy this criterion." All 16 shards are in_progress on 9e4b0e57 as I write this, and the test-plan checkboxes in the PR body are unticked. This is a known-live hazard for this specific change: adding one test to this file moves worker hashes and redistributes shard membership (that is the whole reason E2E coverage: ReportContentEditor column-visibility toggles #1966 was deferred out of PR fix(reports): improve report PDF UX — paragraph breaks, inline meta, inline notes, column toggles #1959 in the first place). Please post the triage comment before merge, and cross-reference E2E hazard: cross-file shared-admin preference writes can silently flip a running test's state #1957 if a cross-file hazard surfaces.

Verified clean, no action

• No production code, schema, API contract, shared types, migrations, or Dockerfile touched — no Schema.md / API-Contract.md / ADR updates are owed by this PR, and nothing here diverges from the documented architecture.
• .claude/agent-memory/product-architect/recurring-patterns.md: content is accurate against the sources I re-checked (API is an object map; tablet/mobile projects both grep: /@responsive/; the dual-layout CSS gate; CI's static-analysis runs no ESLint — in fact on this PR Static Analysis is skipped entirely by Detect Changes, since only e2e/ and .claude/ changed, which makes the local lint policy the only thing standing between this branch and a lint regression). Cross-agent write into my memory file is fine and sanctioned by CLAUDE.md's Agent Memory Maintenance rule. Only the API.<key> convention line needs reconciling with the code, per the MEDIUM above.
• OVERVIEW_COLUMNS / count-parity guard: unchanged and still the right trade-off for an E2E spec.

One <td> assertion block and I'm happy — everything else on the review is closed out. Re-request when pushed.

[steilerDev]

[product-architect] Round 3 re-review of 4cf5a735 (+ 94eda208).

VERDICT: APPROVED

The round-2 BLOCKING finding is resolved correctly. Verification of the three specific questions:

1. Is the <td> locator correct? — Yes, verified against the render path

ReportContentEditor.tsx:251 renders {show('vendor') && <td>{row.vendor}</td>}, and row.vendor is populated at client/src/lib/reportContent/buildReportContent.ts:200 as vendor: invoice.vendorName, which the server derives from a join on the vendors table (server/src/services/invoiceService.ts:272 — vendorName: vendors.name). The test seeds the vendor as ${testPrefix} Toggle Vendor, so the cell's text content — and therefore its accessible name — is exactly that string. exact: true matches.

Two things I specifically checked and cleared:

• text-transform hazard. getByRole(..., { name }) computes the accessible name from DOM text, which is unaffected by CSS text-transform. This is the safe direction of that trap (the failure mode is innerText-based assertions, not accname ones).
• Table semantics. role=cell requires the <td> to be exposed in the accessibility tree, which a display: block table can strip. .table is a plain border-collapse: collapse table (ReportContentEditor.module.css:122), and all 16 E2E shards passed on 3def4a81 with the getByRole('columnheader', { name: 'Vendor' }) assertion already in place — proving the table's semantics reach the a11y tree at desktop. cell rests on the same exposure as columnheader.

2. Is the baseline toHaveCount(1) safe from .mobileCardList inflation? — Yes, doubly

• The mobile card layout renders the vendor value as <span className={styles.mobileCardValue}> (ReportContentEditor.tsx:341), not a table cell. A <span> has no cell role, so it can never match getByRole('cell') at any viewport.
• Independently, .mobileCardList { display: none } at desktop (ReportContentEditor.module.css:279-280; display: flex only inside the max-width: 767px block), so it is out of the accessibility tree anyway.

I also checked the other inflation candidate: the Usage <td> interpolates row.vendor into the EditableField ariaLabel. Per the accname spec, an embedded control inside a name-from-content traversal contributes its value, not its label — and even if it leaked, the full interpolated string is not equal to the bare vendor name, so exact: true excludes it. Only one invoice is seeded, so exactly one body row exists.

Worth noting for the record: the assertion fails loudly rather than vacuously in every mis-scoping scenario. If the locator matched nothing, the new baseline toHaveCount(1) fails; if it matched extra elements, both the baseline and the toHaveCount(0) fail. That is exactly the property the round-2 finding was asking for.

3. Remaining findings — all non-blocking

LOW — new line is not Prettier-formatted (introduced by 4cf5a735). npx prettier --check e2e/tests/budget/reportWizardEditableContent.spec.ts fails, and the sole deviation is the line added by this commit (101 chars; Prettier wants the options object broken across three lines). CLAUDE.md's Local Validation Policy requires npm run format before handback. Not CI-visible here — Detect Changes skips Static Analysis entirely on e2e/+.claude/-only PRs, and CI runs no Prettier check regardless — so this will merge unformatted unless fixed. Please fix before merge with a scoped command (a repo-wide npm run format drags in ~17 files of unrelated drift):

npx prettier --write e2e/tests/budget/reportWizardEditableContent.spec.ts

LOW (carried over) — Scenario 24 docstring is now incomplete. The AC4 paragraph still explains the desktop-only scoping purely in terms of getByRole('columnheader'). The rationale now also covers the cell assertion — and in fact holds more strongly, since the whole table (headers and cells) is display: none at mobile. Optional one-line touch-up whenever the file is next edited.

MEDIUM (carried over, acknowledged) — '**/api/users/me/preferences' hardcoded 3×. Still a follow-up, not a blocker.

Not mine to resolve — AC2 premise error in #1969. testPrefix resolves to E2E-<project><workerIndex>, which is identical for two tests in the same worker despite { scope: 'test' }, so AC2's "values differ" premise cannot hold as written. Correctly routed to product-owner for amendment rather than designed around.

Merge precondition

E2E shards were still in flight at review time (Quality Gates in progress; Static Analysis, Test, Trailer Check, Coverage Report all legitimately skipped by Detect Changes). Since E2E Gates is a main-only required check, the shard covering reportWizardEditableContent.spec.ts will not block this beta merge — but it is the deliverable of this PR, so confirm that shard is green before merging rather than relying on Quality Gates alone.
