test(design): work out the brand match's type match once per page kind Each test ran the font match on the same synthetic pixels, most of them on a fresh worker, and the matches measure full-size screenshots in plain JS, so on a shared CI runner the file passed its 20s cap under load. The type match is now memoised per page kind (brand-fonts.test.ts covers the worker) and the file allows 60s a test. --- .../design/ai/__tests__/brand-match.test.ts | 19 ++++++++++++++++++- 1 file changed, 18 insertions(+), 1 deletion(-) diff --git a/apps/web/src/lib/server/domains/design/ai/__tests__/brand-match.test.ts b/apps/web/src/lib/server/domains/design/ai/__tests__/brand-match.test.ts index 5f25cc87cd..b33b5dba38 100644 --- a/apps/web/src/lib/server/domains/design/ai/__tests__/brand-match.test.ts +++ b/apps/web/src/lib/server/domains/design/ai/__tests__/brand-match.test.ts @@ -28,9 +28,14 @@ import type { HeroAnswer } from '../hero-family' import type { VoiceAnswer, WordsAnswer } from '../words-family' import type { WordsPick } from '../words-pick' import { colourName, followUps } from '../brand-reply' -import { matchType } from '../brand-fonts' +import { matchType, type TypeMatches } from '../brand-fonts' import { BUDGET } from '../brand-match' +// Each match measures full-size screenshots in plain JS (about 2s of CPU a run +// here, several times that on a shared CI runner), so the default 20s cap +// fails on load rather than on behaviour. +vi.setConfig({ testTimeout: 60_000 }) + type Fill = [number, number, number] const W = 1200 const H = 800 @@ -201,6 +206,13 @@ const ALLOWS = { checkCss: () => 'no CSS', } +/** + * The type match for each kind of page, worked out once: it is the same CPU + * work on the same pixels in every test (brand-fonts.test.ts covers the + * worker that runs it in production). + */ +const typeMatches = new Map() + function setup( over: Partial = {}, thin = false, @@ -230,6 +242,11 @@ function setup( order.push(request.family) return answerOf(request.family) as T }) as unknown as BrandMatchDeps['family'], + matchType: async (shot) => { + const key = JSON.stringify([thin, secondLine, ground]) + if (!typeMatches.has(key)) typeMatches.set(key, matchType(shot)) + return typeMatches.get(key)! + }, storeLogo: vi.fn(async () => 'header-logos/2026/11/logo.png'), fallback: vi.fn(async () => ({ ok: true as const,
