From 9da2674fa0a6a7a1c124b3db9cbb46beb4e3d261 Mon Sep 17 00:00:00 2001 From: gsxdsm Date: Thu, 30 Jul 2026 09:34:42 -0700 Subject: [PATCH] =?UTF-8?q?fix(tests):=202=20TaskCard=20reds=20=E2=80=94?= =?UTF-8?q?=20the=20assertions=20pinned=20a=20jsdom=20detail,=20not=20the?= =?UTF-8?q?=20CSS=20(#2782)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## What was red Both failures in the dashboard `app:components-b` lane. **Neither is a style regression** — the CSS is byte-unchanged and correct in both cases. ## Root cause: a jsdom upgrade, not a CSS change jsdom does not substitute `var()`. What it does *instead* changed under us in **4819c2634 (jsdom 27.4.0 → 29.1.1)**: | | jsdom 27 | jsdom 29 | |---|---|---| | unresolvable shorthand (`padding`) | echoes raw text `var(--space-xs) var(--space-sm)` | computes to `"0"` | | single-value longhand (`gap`) | echoes | still echoes | Tests asserting the **echoed string** were pinning a jsdom implementation detail. The bump turned them red with nothing changed in the product. ### 1. `renders a promote action when onPromote is provided` `expected 'var(--space-xs) var(--space-sm)', received '0'`. `.card-promote-action` still declares exactly that padding (`TaskCard.css:1129`). ### 2. `FN-4511 keeps GitHub badge and timer chip geometry in parity` `expected '1px' to be 'medium'`. The chips **are** in parity: - badge: `border: 1px solid transparent` - timer chip: `border: var(--btn-border-width) solid transparent` - `--btn-border-width: 1px` (`styles.css:183`) Here jsdom **discards** the unresolvable width rather than echoing it, so `borderTopWidth` falls back to the initial value `medium`. The existing `|| "1px"` fallbacks could not save it — `medium` is a non-empty string, so it was the fallback that never ran, not the value that was missing. ## The fix Both assertions now read the **declared** value from the mounted stylesheet's CSSOM and resolve a single `var()` against `:root`. That is stable across jsdom versions and is what the assertions always meant. Via the CSSOM rather than a regex over the CSS text **on purpose**: a hand-rolled matcher over grouped selectors silently matches the wrong rule and still reports success. Everything jsdom *can* resolve (font-size, line-height, gap, padding parity) stays asserted against computed style. ## Evidence `components-b`: **1688/1688** (was 2 failed). Mutation-proved — both fail as they should: | mutation | result | |---|---| | timer chip border `1px → 2px` | `expected '2px' to be '1px'` | | promote padding tokens changed | `expected 'var(--space-sm) var(--space-lg)' to be 'var(--space-xs) var(--space-sm)'` | **My first border mutation passed**, which would have read as a vacuous guard. It had patched the wrong one of five identical `border: var(--btn-border-width)` lines in the file. Re-run against `TaskCard.css:1094` it fails correctly. Recorded because the mutation, not the guard, was the thing that was wrong — a passing mutation is a claim that needs checking too. `pnpm lint` clean. Test-only — no production file or CSS touched (mutations reverted; `git diff` clean). ## Ownership `packages/dashboard/app` belongs to the **batch-dashboard-app** owner (u12) under the mega-batch split. This is fix-forward on a red rather than a conversion, confined to one test file, and touches no production code — it should not conflict with the batch. ## Not fixed here The `app:app` lane has **10 pre-existing failures** in `App.test.tsx` (deep-link handling, board branch filters, FN-5817 mobile shell). They were masked by this lane failing first — the runner skips remaining lanes after the first failure, so they only became visible once components-b went green.
