An ecommerce web or mobile application has four important elements in its structure, and they are:
Category / Product Type Pages – The product page consists of options such as product size, color, and type. There is sorting feature to filter out products based on price, model, size, etc. There is also “Add to Cart” or “Add to Wishlist” feature present in the category pages.
Product Description Page – Consists of product title, description, product images, related products, Add to Cart feature, Product comparison, additional product info, etc.
Shopping Cart – Products list view, removing product from the list, cash on delivery option, Select delivery option, card payment, pay now option, etc.
Before you conduct functionality testing, we need to understand the ecommerce website or application very well. The above mentioned features are commonly found on all ecommerce applications, yet most of them are customized as per business requirements.
2) Testing Ecommerce Application Workflow

You need to check whether the payment is processed correctly, by using all kinds of payment methods such as net banking, Credit/Debit card, PayPal, etc. You can check all these using dummy accounts and demo debit/credit card numbers. Also, you need to check whether the orders are cancelled, and the payment ID sent back.
Check whether the invoice and emails generated after the payment process are sent.
You need to also ensure the refund process, email, and refund receipt all are working properly.
