Implementing them as +described would waste effort or introduce a needless change. + +### Item 2 is NOT an override problem — `[test].environment` is not a real bun option + +The brief asks to "confirm the root sets `environment = "happy-dom"` and packages/ui overrides it". +That is not what happens. **Bun 1.4.2 has no `[test].environment` key at all** — it is silently +ignored, not overridden. Proven with a minimal repro outside the repo: + +``` +/tmp/bftest/bunfig.toml -> [test]\nenvironment = "happy-dom" +/tmp/bftest/a.test.ts -> expect(typeof document).toBe("object") +$ bun test => 0 pass / 1 fail ("document is not defined") +``` + +So the root `bunfig.toml` line has **never** provided a DOM. `packages/ui/bunfig.toml` is +correct and is the only thing that works (via `preload` → `GlobalRegistrator.register()`), which +is why `cd packages/ui && bun test` gets a DOM but a root-level run does not. Bun reads the +bunfig next to the CWD, not one per test file — so a root run never sees `packages/ui/bunfig.toml`. +The fix is to give the **root** a `preload`, not to re-declare an environment that does nothing. + +### Item 4 — the DataTable stale closure does NOT fail; no fix required + +`sorts descending on second click (stale closure test)` **already passes**, 3/3 tests green, +confirmed stable over 5 consecutive runs. The failures you saw for `DataTable.test.tsx` were +100% the missing-DOM error from item 2, not the sort logic. + +Why the "bug" is latent rather than active: `fireEvent.click` wraps each click in its own +`act()`, so React flushes the state update and re-renders between the two clicks. `handleSort` +is therefore re-created with a fresh `sortDir` before the second click reads it. The closure is +only stale for two clicks dispatched inside a *single* batch, which no test does. + +`setSortDir(prev => prev === "asc" ? "desc" : "asc")` at `DataTable.tsx:34` is still the +correct-by-construction form and I'd take it in review, but it is **out of scope** under +"fix only what tests require". Flagging as Info, not actioning. + +### Item 5 — the root cause is zero-padding, not field ordering + +`date.ts:1-11` claims explicit field order "overrides locale ordering — produces M/D/YYYY". +That comment is wrong. Measured on this runtime: + +``` +en-AU {month:"numeric", day:"numeric", year:"numeric"} -> 15/06/2024 | 01/03/2024 (current) +en-AU {day:"numeric", month:"numeric", year:"numeric"} -> 15/06/2024 | 01/03/2024 (identical!) +``` + +`Intl` ignores the order you list the option keys in — `en-AU` is already day-first, so +test 1 (`/^15/`) passes today. Reordering the keys changes **nothing** and does not fix test 2. + +The real problem: ICU's `en-AU` short-date pattern is `dd/MM/y`, so `day:"numeric"` is coerced +to 2-digit `01`, failing `/^1/`. The suggested `dateStyle:"short"` *would* pass both assertions +(`1/3/24`) but silently truncates the year to 2 digits — a regression for a date formatter, and +it also contradicts `formatDateTime`, which keeps a 4-digit-year style. Hence the +`formatToParts` fix below, which strips the day's leading zero and keeps `DD/MM/YYYY` intact. + +--- + +## The 5 fixes + +### 1. `apps/web/src/lib/api.ts` — broken import + re-export (2 lines) + +Fixes `api module > imports without error` and `useSearchDebounce is exported`, plus TS2305. +The hook's real current name is **`useDebounce`** (`packages/utils/src/hooks/useDebounce.ts:10`, +exported at `packages/utils/src/index.ts:1`). `useThrottle` no longer exists anywhere. + +- **Line 11:** `import { useThrottle } from "@e2e/utils"` → `import { useDebounce } from "@e2e/utils"` +- **Line 32:** `export { useThrottle as useSearchDebounce }` → `export { useDebounce as useSearchDebounce }` + +Keep the `useSearchDebounce` public alias — `api.test.ts:13` asserts that exact name. + +### 2. `bunfig.toml` (root) — replace the no-op `environment` with a `preload` + +Fixes all 6 `ReferenceError: document is not defined` failures. bunfig is config, not a test file. + +```toml +[test] +preload = ["./packages/ui/test/setup.ts"] +``` + +`packages/ui/test/setup.ts` is already correct (registers happy-dom globals) — no change needed +there. Leave `packages/ui/bunfig.toml` as-is so `cd packages/ui && bun test` keeps working +(verified: 6 pass). This also makes the bare `bun test` invocation work without relying on the +`--preload` flag that `package.json`'s script passes. + +### 3. `packages/ui/src/components/Button/Button.tsx` — apply `aria-label` to the element + +Two tests need this. `Button.test.tsx:18` requires the passed label to reach the DOM; +`Button.test.tsx:28` requires a non-null `aria-label` even when **none is passed**. The prop is +destructured as `ariaLabel` (line 35) but never rendered — the `
