A regional storefront opens its market selector, but a keyboard user cannot finish choosing a country or return to the page. A screenshot of the visible dialog misses this failure. Test the actual focus path through opening, delayed options, cancellation and confirmed selection.
This guide proposes an authorized website QA procedure, not a claim that a particular browser, proxy or site has passed accessibility certification. A regional route selects the network context; keyboard usability must be checked in the application itself.
1. Define the market-selection workflow
Use an owned staging page with a known market, supported locale and harmless test profile. Write down the opening control, initial choice, selection mechanism, cancel action and expected destination after confirmation. Decide which action actually commits the new market.
The W3C APG modal-dialog pattern describes focus entering the dialog, Tab and Shift+Tab staying within it, Escape closing it and focus returning to the invoker or a logical replacement. Use that pattern when the component is genuinely modal; a nonmodal popover needs its own interaction contract.
A market switch may replace the document or route instead of closing in place. Specify the expected focus destination for that navigation separately. Do not fail an intentional page transition merely because the old trigger no longer exists, but do not accept focus disappearing without a usable continuation.
2. Establish a keyboard-only control run
- Start from a clean test profile and record the active market, locale, browser build and viewport.
- Reach the market trigger by keyboard, noting its visible focus indicator and accessible identity.
- Open it using the control's documented key and record the active element immediately afterward.
- Traverse all operable controls in both directions. Record the first and last focus stops and whether background controls become reachable while the modal is active.
- Cancel without changing the market. Confirm the documented return target and unchanged market state.
Use actual keyboard interaction for acceptance. Directly assigning focus or changing the selected value in a test script can help diagnose a component, but bypasses the path a user needs. Record those diagnostic actions separately.
A visible focus ring alone is insufficient if it marks a hidden or covered control. Check that the focused control is visible and can perform its declared action at the tested viewport.
3. Hold option loading at a known point
On an owned test system, delay the option response with a controlled fixture rather than relying on a proxy to be randomly slow. Open the selector before releasing the response. Record where focus starts, what can be operated while loading and how cancellation behaves.
Release the matching response and verify that focus remains on a usable element. A rerender can remove the focused node even though the dialog looks unchanged. Check the actual active element and the next keyboard action after the new options appear.
Repeat with a documented empty result and a recoverable load error. The user must have a working continuation under the agreed design, such as retry or cancellation. Do not mark the case passed just because an error message became visible.
4. Verify selection and commit separately
Choose a harmless supported market with the keyboard interaction appropriate to the actual widget. A native select, a radio group and a custom listbox have different internal key behavior; do not impose a universal arrow-key rule from the surrounding dialog.
Record the selected option before confirmation, then activate the commit action once. Check the resulting market identifier, relevant page state and focus destination. If confirmation navigates, wait for that destination's readiness signal and inspect its continuation rather than a detached element from the old page.
Reopen the selector and verify its chosen value reflects the committed market. In a separate reset case, change the candidate option and cancel; confirm the old market remains according to the documented cancel contract. Similar visible labels must be distinguished by stable option identity.
5. Test replacement, reopening and long labels
Use an owned fixture where the header rerenders or the original trigger is replaced before closure. Verify the planned logical return target still exists and is usable. A selector that stores only an obsolete element reference can strand focus after a regional layout update.
Open and close the dialog a small fixed number of times, then press the activation key once. Confirm only one dialog and one market commit occur. Duplicate listeners can make a reopened selector appear to work while submitting the action twice.
Test a supported locale with longer option text at the agreed narrow viewport. Traverse and commit again, checking that the focused option and action remain visible. Keep the market and data fixture fixed so this case isolates the layout change.
6. Compare regional routes with the same fixture
The 98IP dynamic residential IP page is relevant when choosing access for authorized regional website checks. Use the API configuration page to confirm current access and account options. A regional proxy does not guarantee which dialog variant or language the site chooses; record those application inputs.
- Open and cancel: keyboard entry and usable return target.
- Forward and backward traversal: no unintended background focus.
- Controlled delayed options: focus survives the matching update.
- Empty or error state: a working declared continuation remains.
- Confirm versus cancel: market state follows the separate contracts.
- Replacement and reopening: no lost focus or duplicate commit.
These cases are unexecuted. For each route, use an independently reset profile with the same browser, fixture, market and viewport. Log the key sequence, active-element identity, option-response case ID, selected and committed market, return target and first mismatch. Redact secrets and retain synthetic profiles only.
FAQ and release checklist
Does a visible dialog prove it is usable? No. It must support the tested opening, navigation, action and exit sequence.
Does one keyboard run prove full accessibility? No. Report this bounded workflow result. Assistive-technology and other accessibility checks remain separate work.
- Modal versus nonmodal behavior is declared.
- Opening, loading, selection and closure have observable focus destinations.
- Cancellation and confirmation use separate reset cases.
- Dynamic updates do not remove the user's continuation.
- Actual keys, not only programmatic state changes, are tested.
- Only authorized test profiles are used, with no orders, payment or unsupported certification claim.
