The Sort Label Is Right, the Products Are Wrong: A Regional Proxy Test

A regional product page displays the translated equivalent of “price: low to high,” but the products stay in the opposite order. A screenshot confirms the label, not the selected machine value or the receiver's sort rule. An authorized residential-proxy comparison should trace the choice from the current option through the request to an independently expected product sequence. This is a controlled QA design, not a measured result or compatibility promise.

1. Define a small catalog with an independent answer

Use an owned staging catalog with three synthetic products: item A priced at 4 units, item B at 12 and item C at 7, all in the same currency and price basis. Agree with the owner that price_asc must return A,C,B and price_desc must return B,C,A. These are fixture values, not 98IP prices or observations of a live store.

Keep all three products available in every tested locale and region. Freeze inventory, promotions, filtering, tax basis and catalog version for the comparison. Use unique prices first so tied-price policy cannot conceal a reversed sort. Record expected IDs independently of the application's sorting code; visually increasing rounded prices alone are insufficient evidence.

Confirm whether the contract sorts numeric unit price, sale price, tax-inclusive price or another field. If a region genuinely has a different assortment or price basis, create a separate owner-approved expected sequence rather than calling every difference a proxy failure.

2. Separate translated labels from stable option values

For a native single-select control, inspect the current selected option, select.value and the option's explicit value. If an option has no value attribute, its text supplies the value; translating that text can therefore change the transmitted identifier. Prefer the owner's stable keys while localizing display labels. Do not send an option's list position as a permanent sort identity.

Read current state rather than assuming the HTML selected attribute still identifies the user's choice. That attribute defines the default selection; the live option.selected property represents current selection. Capture the UI state after the real user interaction and before submission or navigation changes it.

For a custom dropdown, identify its application state and the actual hidden or serialized field instead of assuming native select behavior. Do not treat a styled text box as proof of a native option value. Record the control type, field name and mapping contract, without promising the same implementation across browsers.

3. Run a reversible selection matrix

1. Load the frozen staging fixture through an approved baseline. Select the ascending option using its stable value through the real supported UI path; verify the localized label and current machine key agree.
2. Capture the outgoing request's actual sort parameter and the receiver's decoded value. Preserve a non-secret attempt ID, catalog/build version, method and path. A label change without the intended request is not a completed sort test.
3. Compare response product IDs with A,C,B, then compare rendered product IDs in order. Check all three IDs occur once and remain associated with their fixture prices.
4. Select descending and expect B,C,A; then switch back to ascending and expect A,C,B again. Wait for the specific request and render acknowledgement rather than a fixed arbitrary delay.
5. Repeat with keyboard operation supported by that control. On a separate authorized localized fixture, reorder the option list while preserving stable values; the ascending choice must keep its identity even at a new list position.
6. Repeat the matrix through the selected regional residential route, holding session policy and initial page state equivalent. Record actual egress, locale and build; compare one changed dimension at a time.

Do not change a native value only through a console assignment and claim that the normal application change path was tested. Exercise the real interaction, or explicitly label a separate programmatic test. If a request never finishes, record a transport or readiness limitation rather than accepting the last visible order.

4. Locate the first divergent boundary

• Label says ascending but live key is descending: inspect translated option mapping and component state.
• Live key is correct but the request sends a label or index: inspect serialization and mapping, especially after locale-specific option reordering.
• Request contains the correct stable key but the receiver decodes another value: inspect parameter naming, duplicate parameters and documented parsing with the owner.
• Receiver sees the correct key but response IDs are wrong: inspect server sort field, direction and frozen catalog assumptions.
• Response IDs are right but rendered order is wrong: inspect client-side re-sorting, stale state or an older response overwriting the latest selection.
• Only one route differs: compare region-specific deployments, cache keys and received request IDs before attributing the outcome to the IP.

Do not sort displayed prices as text to manufacture a passing screenshot. The fixture deliberately includes 4,7,12 so a string-based numeric mistake can become visible. Keep product IDs attached to the correct values throughout the request, response and rendering comparison.

5. Add edge cases only after the core passes

Then test two equal prices with the owner's documented tie-break rule, missing prices, an empty catalog and pagination. If ties have no stable contract, report that uncertainty instead of asserting an exact ID order. A first page with increasing values does not establish ordering or completeness across all pages; the paginated data integrity guide covers that separate acceptance boundary.

Keep a negative control: on an isolated synthetic test stub, intentionally map the ascending choice to the descending key. The independent expected-ID check should fail even if the label still looks correct. Restore the reviewed mapping and rerun both directions and the return switch. This demonstrates that acceptance checks the outcome rather than echoing the UI's own value.

Retain fixture/version IDs, expected and observed sequences, current selected key, redacted request/receiver values and render acknowledgement. Avoid real customer data, cookies, authorization headers and proxy credentials. Do not submit orders, create leads or generate real ad interactions as part of this catalog test.

6. Use 98IP for the controlled regional route

When authorized catalog testing needs a residential network perspective, review the 98IP residential proxy product page and API configuration documentation, and use the method and parameters supported by your account. Keep the route's session policy stable during the ascending/descending/return sequence and check actual usage.

A proxy supplies the network path. It cannot repair translated enum keys, text-based price sorting or a stale component, and it does not guarantee a target's sort results or browser compatibility. Limit synthetic traffic and respect site authorization.

• Sort field, price basis and stable ascending/descending keys are owner-approved.
• Expected ID order is independent of application code and identical across equivalent fixtures.
• Current selection, serialized key and receiver value agree despite translated or reordered options.
• Response and rendered IDs match, with no lost, duplicated or reassigned products.
• Both directions and the return switch pass; a deliberately wrong mapping is detected.
• Region, locale, egress, catalog version and unresolved edge cases are recorded honestly.

Does the correct translated label prove the right sort? No. Verify the stable key and product-ID sequence.

Can I select the second option in every language? List position may change. Test the approved stable value and actual UI path.

Will changing the proxy fix a reversed order? It does not fix a mapping or comparator. Investigate route differences with controlled request and deployment evidence.
