Why Test Ecommerce Websites?

• Rigorous testing ensures positive User Experience, which is a competitive edge in such a crowded field.
• Retail E-commerce sales is projected to grow considerably in the next few years.
• E-commerce website performance is a direct contributor to conversion rate, and performance testing reveals areas of low performance (high loading speed, poor responsiveness, etc.) to improve.
• Users visit E-commerce websites from a wide variety of devices, browsers, and OS, calling for robust cross-browser testing.

Types of Testing For Ecommerce Websites

No matter what website you are testing, these are always the testing types that you should consider when developing your test plan document.

• Functional Testing: this involves testing individual functions of the E-commerce website to ensure they work correctly according to the defined requirements. All components of an E-commerce site, such as product search, shopping cart, and payment processing, should undergo functional testing.
• Integration Testing: integration testing is simply checking if 2 or more components are working together as expected. E-commerce websites require a lot of communication and data transferring from 1 component to another. That’s not to mention the integrations between the site with external third-party plugins/services. 
• Visual Testing: the quality of product images does impact the final buying decision of customers, and a visually buggy product page (overlapping text, missing images, blurry images, etc.) is enough to drop their trust. Visual testing helps testers identify those pitfalls and make timely changes.
• API Testing: considered as a subset of integration testing, API testing ensures that the API used on the website is working properly, transferring and retrieving the right data, and its usage is monitored closely.
• Performance Testing: considered as a non-functional testing type, performance testing does not check if the feature works, but rather if the feature works at the required speed, efficiency, and reliability.
