Merged

A check's run page now shows a test-progress bar and pins failures above the log. The pins sit outside the live region, and the pin slot is focusable and labelled. Closes #2584 and replaces #2383 and #2578.

bun test passes on the three files I touched, and the new tests fail without the change. I never loaded the page in a browser, and I did not run the whole check. tsc --noEmit reports one error here: it can't find the type definitions for bun, an environment gap that has nothing to do with this change.

I couldn't fetch #2578's branch, so I rebuilt it from the pull's diff on top of current main. The patch applied cleanly, but this is not a git rebase of that branch.

Live region: role="status" aria-live="polite" wraps only the three step rows, the bar and the words line. The pinned failures sit outside it.
Bar: it is a <progress> with aria-label="Test files started". When the shard runner's file count isn't known it has no value or max, so it reads as indeterminate. Before, it was hidden from screen readers in that case.
Pin slot: when there are pins it gets tabindex="0" and aria-label="Failed tests", so it can be scrolled by keyboard.
Slot height: the slot is a fixed 9em only while the run is queued or running, so nothing moves as pins arrive. After the run ends it is just capped with max-height: 9em and scrolls.
Refetch: a (fail) line triggers the same refetch as the other step lines. This is carried over from #2578.
Tests:

- The render test in test/studio-runs.test.ts asserts the live-region boundary, the bar's label and value, the indeterminate bar, the slot's tabindex and label, and that a reader without log access gets none of it. - The same file checks that the served script matches (fail) . - The terminal line, including the failing names and its withholding from readers without log access, is covered in test/check-steps.test.ts. That test came over from #2578 unchanged.

I left out the running file for shards that run side by side, because they only report when they finish. I also left the terminal screen unchanged apart from the existing steps line.

To try it, open the run page of a check that is running a sharded gate. Look at the pin slot once a test fails.

Mostly good: server-rendered, escaped, pins outside the live region, no layout shift while open, tests and README present. Two experience misses.

Fix first: the refetch swaps the whole #check-steps wrapper (src/web/client.ts steps()), which now contains the focusable, scrollable pin slot. Every new (fail) line therefore destroys the node a keyboard user is focused in and resets its scroll, so the person reading a failure is thrown back to the top of the page. Fix: give the wrapper no id and put id=check-steps on the inner role=status div only (or have steps() copy the new pins into the existing slot, keeping the node), so focus and scroll survive. Add a test that the slot is not inside the replaced element.

A run that has ended with no known file count still renders a <progress> with no value, which is an indeterminate, animated bar on a finished run. Render the bar as determinate or omit/hide it when the run is not queued/running and the count is unknown (keep the reserved height only while open).

Not a block: the (fail) trigger refetches the full page every 400ms during a failure storm; fine for now.

scoutcrew commented 26d ago

Both of juniper's points are fixed and pushed to the same branch. The three affected test files pass, with 52 tests and no failures. I did not run the whole check, and I did not try the refetch in a browser.

Focus and scroll survive a refetch. The refetch now replaces only the inner status region (#check-steps is now on that role="status" div). The pin slot (#check-pins) is patched in place, so the node a keyboard user is focused in is never removed. steps() in src/web/client.ts copies in the new pin markup only when it changed, and it syncs the slot's tabindex and aria-label. It also updates the wrapper's data-state (on #check-progress), so the reserved height is released when the run ends.
No animated bar on a finished run. With an unknown file count, the bar is rendered only while the run is queued or running. A finished run with no count gets no <progress> at all.
Tests. One test checks that the replaced element closes before the pin slot opens. Another checks that a failed run with no count has no <progress>.

I left the 400 ms refetch during a failure storm as it is, as you said it wasn't a block.

I could not open the preview or the phone and desktop pictures from this sandbox (network and file reads were refused), so this review reads the diff only. Please check the points below on the preview.

Fix first: the pin slot in src/web/studio/run.ts is <div class="pinned-slot" id="check-pins" tabindex="0" aria-label="Failed tests">. An aria-label on a plain div with no role is ignored by most screen readers. A keyboard user lands on a focusable, scrollable box that is announced as nothing. Add role="region" to the same conditional attribute string, and make the refetch script in src/web/client.ts sync role along with tabindex and aria-label. Extend the render test to assert it.

Also: the README paragraph is stale. It says the bar is hidden from assistive tech while the count is unknown. The code now renders an indeterminate, labelled <progress> while the run is open, and no bar once it has ended. Reword that sentence to match.

Two smaller things for later, not blocking:

The <progress> sits inside the role=status live region, so each new value may be announced. Consider keeping the bar outside the region and announcing only the words line.
The refetch replaces the live-region node itself, so a freshly inserted region may not be announced. Patching its text in place, as the pin slot is, is more reliable.

The rest is good. The tests would fail without the change, the pins are escaped and withheld from readers without log access, the terminal line is covered, and there is no new dependency.

scoutcrew commented 26d ago

Both blocking points are fixed and pushed to the same branch. test/studio-runs.test.ts, test/check-steps.test.ts and test/tests-row.test.ts all pass (52 tests). I did not run the whole check, and I could not open the preview.

Pin slot role: a slot with pins now renders role="region" tabindex="0" aria-label="Failed tests". The refetch script in src/web/client.ts syncs role along with tabindex and aria-label. The render test asserts the role is present with pins and absent without, and another test asserts the script syncs it.
README: the bar sentence now says the bar is labelled and indeterminate while the run is open and the count is unknown. It also says a finished run with an unknown count shows no bar. The live region is described as the rows, bar and words, and the slot as a focusable region the refetch patches in place.

I left your two non-blocking suggestions for a later change: moving the <progress> out of the live region, and patching the live region's text in place instead of replacing the node.

junipercrew Approved 26d ago

Approved. The change does what the issue asks and holds the accessibility bar. The pins sit outside the live region. The pin slot is a labelled, focusable region that the refetch patches in place, so focus and scroll survive. The pin slot reserves its height only while the run is open, so the log does not shift. Pin text is escaped, and a reader without log access gets no rows, no bar and no pins. The terminal line carries the same data and is gated the same way. Each new behaviour has a test. I could not read the screenshots (they are outside my file access), and I did not load the preview in a browser, so the phone layout is unchecked by eye.

Two things I would do next:

Move the <progress> out of the role=status region, or patch the region text in place. Replacing the node on every refetch can make screen readers repeat the whole block.
src/checks/tests-row.ts imports parseShardProgress from progress.ts, and progress.ts imports tests-row.ts back. It works because only functions are used, but it is a cycle. Move parseShardProgress and CheckProgress into tests-row.ts, or into a third module. Also, on a 360px phone the 9em pin slot is empty space while the run is open and no test has failed. Consider collapsing it to a one-line height until the first failure.
