Is my site ready to launch? What should I check?

Test your website before launch in three passes. First, walk through the key flows end to end as if you were a customer: sign-up, ordering and a test payment. Second, open it on a real phone and in two different browsers. Third, review the text, links, forms and error messages. Write down every problem with steps to reproduce, and fix whatever stops a customer from finishing first.

Test payments in the test mode your payment gateway provides, with the test cards published in its official documentation, and never use a real card or give one to any tool. Try a successful payment, a declined one, a cancellation halfway through and a refund, and confirm that the order status in your system matches what really happened. Then make one small real payment yourself before opening.

Testing an Arabic site goes beyond reading the text. Check that the whole layout is mirrored: menus, arrows, icons and column order. Check that numbers, phone numbers, emails and prices keep their correct order, that text mixed with English does not scramble, that forms accept Arabic input, and that search finds words with different letter forms. Then try the English version to confirm switching languages breaks nothing.

Run tests on three occasions: before every release or update, however small; after every fix, to confirm the bug is gone and nothing new appeared; and on a regular schedule even when you changed nothing, because outside services such as payments and messaging can change without telling you. A site that sells every day deserves a quick daily check and a full weekly one.
