Fixed two flaky admin acceptance races - #30369
Conversation
no ref The tier detail modal's Save commits two resources in sequence: the tier itself, then the checkout configuration. `handleSave` flips the button to "Saved" as soon as the tier write resolves, and only then does `onOk` call the checkout section's save. Two specs waited on "Saved" and read the checkout capture synchronously on the next line, so they asserted against a request that had not necessarily been issued yet. That race was the single largest source of admin acceptance failures on main: it accounted for every failing run sampled over the last two days, surfacing either as `Cannot read properties of undefined (reading 'tiers_checkout_config')` or `expected [] to have a length of 1`. Both now poll the capture, matching the sibling spec in the same file that already does. Reproduced by delaying the checkout write, which fails both specs with the exact CI errors and passes with this change.

WalkthroughThe membership acceptance tests now synchronize with asynchronous UI and API operations. Checkout tests poll until the chained configuration PUT request is recorded. The access settings helper waits until the dropdown option list is removed before returning. Suggested reviewers: Merge Risk: 🔵 Low · up to The PR only changes admin acceptance-test synchronization and should not affect product behavior. It is mergeable with owner awareness that the tier-save test explanation still needs a small wording clarification. 🚥 Pre-merge checks | ✅ 6✅ Passed checks (6 passed)
Full details: Type-Safe BoundariesExplanation PASS. The pull request changes only two acceptance test files. The custom check explicitly says never fail for tests. The changes add polling and DOM teardown waits; they do not introduce boundary-data consumption, ✨ Finishing Touches📝 Generate docstrings

386-387: LGTM!
no ref `choose()` clicked a select trigger, clicked an option, and returned. Choosing an option starts Radix's close but does not finish it: measured at the instant the helper returns, the option list is still mounted and the body still carries `pointer-events: none`. Everything the caller does next races that teardown. Losing the race fails in two ways, both silent at the point of the mistake. A click can be refused outright — Playwright waits for pointer events the body is suppressing and times out — or it can open a layer that the teardown then dismisses, so the next dropdown never opens and the failure only surfaces at the assertion that waits for its options. The second is what CI hit: "Matcher did not succeed in time" on the tier option after the tiers combobox was clicked open. `choose()` now waits for the dropdown to unmount, which also restores the body's pointer events. The same shape exists at roughly twenty other call sites across the suite, but not all of those dropdowns are single-select — the bulk-actions label picker stays open by design — so each needs classifying rather than a blanket sweep.

Two independent races in the admin acceptance suite, both of which made CI red
on main. Each was reproduced before fixing, and the full suite (70 files, 676
tests) passes locally with both changes.
Tier checkout: asserting on a chained write
The tier detail modal's Save commits two resources in sequence: the tier
itself, then the checkout configuration.
handleSaveflips the button to"Saved" as soon as the tier write resolves, and only then does
onOkcall thecheckout section's save. Two specs waited on "Saved" and read the checkout
capture synchronously on the next line, so they asserted against a request that
had not necessarily been issued yet.
This accounted for every admin acceptance failure sampled on main over two
days, surfacing as either
Cannot read properties of undefined (reading 'tiers_checkout_config')orexpected [] to have a length of 1. Both specsnow poll the capture, matching the sibling spec in the same file that already
does.
Reproduced by delaying the checkout write, which fails both specs with the
exact CI errors and passes with this change.
Access settings: interacting during a dropdown's teardown
choose()clicked a select trigger, clicked an option, and returned. Choosingan option starts Radix's close but does not finish it. Measured at the instant
the helper returned, the option list was still mounted (4 options) and the body
still carried
pointer-events: none.Losing that race fails in two ways, both silent at the point of the mistake: a
click is refused outright — Playwright waits for pointer events the body is
suppressing, which reproduces as a
locator.clicktimeout — or it opens alayer the teardown then dismisses, so the next dropdown never opens and the
failure only surfaces at the assertion waiting for its options. The second is
what CI hit, which is why it failed at the tier-option assertion rather than at
the click before it.
choose()now waits for the dropdown to unmount, which also restores thebody's pointer events (re-measured: 0 options,
pointerEvents: "").Follow-up, deliberately not in this PR
The same shape — pick an option, immediately touch the next control — exists at
roughly twenty other call sites across eleven files. It is not a mechanical
sweep: not all of those dropdowns are single-select, and the bulk-actions label
picker stays open by design, so waiting for unmount there would hang. Each site
needs classifying, ideally behind a shared harness gesture documented as
single-select only.
Also still open: one observed flake at
navigation-history.acceptance.test.tsxline 78, where
flushEffects()waits a fixed number of frames for the dirtyflag to reach the history blocker. It could not be reproduced locally, and the
obvious readiness probe is unusable because MSW's browser worker tears itself
down on
beforeunload.
