What to test in Liechtenstein
Start with a local question. Keep the network, language, and delivery settings separate so the result tells you something useful.
Do not let the shop substitute Switzerland
For Liechtenstein checkout QA, choose Liechtenstein explicitly and inspect the destination carried into the order summary. A storefront may reuse Swiss content or currency formatting. That does not prove the selected address is supported, so preserve the country field with each result.
Compare Vaduz and another supported address
Use a Vaduz test address and another Liechtenstein address your service supports to exercise validation and delivery methods. Keep product and language unchanged. This is a useful local application test even when the proxy dashboard exposes only country selection.
Compare German-language markets carefully
For Liechtenstein, Switzerland, and Austria comparisons, retain the original currency and the storefront's selected country. Match the same seller and item where possible. Similar German descriptions should not cause the exporter to merge separate offers into a single regional price.
