Short answer
A complete Shopify shipping test covers configuration and customer experience. Verify each market, zone, profile, origin, rate condition, and carrier response; then repeat the same scenarios on the product page, cart, cart drawer, and checkout. Use a fixed test matrix so changes can be compared over time. Include unsupported destinations and failure states—not only successful orders—and record the expected result for every case.
Build a representative test matrix
Choose destinations that represent metro, regional, remote, international, and unsupported areas. Choose products that represent standard, heavy, oversized, special-profile, and multi-origin fulfilment. Combine them into single- and mixed-profile carts.
Test condition boundaries
Check the exact values below, at, and above every price and weight threshold. Include discount effects, currency context, free-shipping thresholds, zero-weight products, and the highest supported order value or weight.
Test every customer surface
Compare the product estimate, cart estimate, cart-drawer estimate, and final checkout result using the same address and cart. Differences can be legitimate, but they should be understood and explained.
Turn the matrix into regression testing
Repeat the matrix after changes to products, profiles, locations, markets, themes, carrier accounts, or shipping apps. Record the date, configuration version, expected rate, actual rate, and owner of each failure.

Questions
How many destinations should I test?
At minimum, test one representative address from every commercially important zone plus remote and unsupported cases.
Should a product-page estimate always equal checkout?
Not necessarily. Checkout has the full cart and address. The product page may estimate a single item with less complete context.
When should I rerun the checklist?
After changing markets, zones, profiles, locations, products, carrier settings, apps, or the storefront theme.
