A 10-minute WooCommerce test to run after plugin updates

A checkout page can look fine after a plugin update while the underlying order process is broken. The article recommends testing whether one controlled order passes through every connected system, not just whether the page loads. The suggested steps include adding a product to the cart from a private browser window, submitting the form with a required field empty to check error handling, and verifying totals including tax, shipping, discounts, and fees. They also advise using a test payment method and confirming that exactly one order is created, stock is updated, and emails and webhooks fire. Each test should be logged with its date, versions, route, order ID, and expected versus actual results.
