Website QA Checklist

Website QA Checklist

A website is often the first interaction customers have with a business. Whether it is an eCommerce store, SaaS platform, corporate website, or online service, users expect a website to be fast, secure, responsive, and easy to use. A structured Website QA Checklist helps testing teams identify defects before they affect customers and ensures that every important part of the website is validated before release.

011. Functionality Testing

Functional testing verifies that the website works according to business requirements. Testers should verify homepage functionality, registration, login, logout, search, navigation, buttons, forms, file uploads, and error messages. Both valid and invalid inputs should be tested to ensure the application handles different user actions correctly.

022. UI and Usability Testing

A website should provide a consistent and user-friendly experience. Check page layouts, fonts, buttons, images, icons, menus, pop-ups, forms, and loading indicators. Testers should also ensure that important information is easy to find and that there are no overlapping or incorrectly aligned elements.

033. Navigation and Link Testing

Broken links can negatively affect user experience. Verify navigation menus, footer links, internal links, external links, breadcrumbs, CTA buttons, and redirects. Invalid URLs should display the appropriate error page, while valid links should take users to the intended destination.

044. Form Testing

Forms are essential for registration, login, contact requests, subscriptions, and transactions. Verify required fields, optional fields, email validation, phone numbers, character limits, special characters, error messages, and successful submissions. Duplicate submissions and invalid inputs should also be tested.

055. Cross-Browser and Device Testing

Websites should work consistently across major browsers and devices. Test on Chrome, Firefox, Edge, and Safari, along with desktops, tablets, and smartphones. Validate responsive layouts, touch interactions, menus, images, text readability, and device orientation.

066. Performance Testing

Performance testing verifies that a website remains responsive under different workloads. Check page load time, server response time, API response time, concurrent users, CPU usage, memory usage, database performance, scalability, and behavior during peak traffic. Performance and load testing can help identify bottlenecks before production.

077. Security Testing

Security testing helps protect websites and user information. Verify HTTPS, authentication, authorization, session management, cookies, input validation, SQL injection protection, XSS protection, CSRF protection, and access controls. Sensitive information should never be unnecessarily exposed.

088. API and Accessibility Testing

Modern websites often depend on APIs, so testers should validate status codes, authentication, request and response data, error handling, response time, and data consistency. Accessibility testing should cover keyboard navigation, focus indicators, image alternative text, color contrast, headings, forms, and screen-reader compatibility.

099. SEO and Content Testing

QA teams should also verify page titles, headings, URLs, internal links, image alt text, redirects, XML sitemap availability, and robots.txt configuration. Content should be accurate, readable, and free from spelling, grammatical, or placeholder errors.
