What to test in France
Start with a local question. Keep the network, language, and delivery settings separate so the result tells you something useful.
A French IP is only one part of a French storefront
Use a France route to inspect a site's response to a French network origin, then set the storefront language and delivery country explicitly. Keep the seller, product variant, and basket unchanged. A French-language page can serve several markets, so save the selected market with the result.
Compare Paris and Lyon without changing the exit
For a France checkout test, enter a Paris delivery postcode, capture the available methods and total, then repeat with Lyon. This tests the shop's delivery rules. Run an overseas destination as its own scenario when relevant; a country-level exit does not establish a city's location or delivery eligibility.
Make French search observations comparable
For France SEO monitoring, retain accents in the query and record browser language, device, and the search engine's displayed location. Repeat the same settings for a Belgium comparison if useful. If only the query language changes, label it as a language test rather than a network-country comparison.
