Web (Word Wide Web)

Web (World Wide Web) refers to the vast system of interconnected documents and resources, accessed via the internet using web browsers. It encompasses the web pages, applications, and services that are part of the internet and forms the basis for much of the modern software, particularly web-based applications and services. Web testing, or testing of applications running on the web, ensures that these resources and applications function correctly, are secure, and provide a seamless user experience across different platforms and devices.

Key Aspects of Web Testing:

1. Web-Based Applications:
   • Software accessed via browsers, using technologies like HTML, CSS, JavaScript, and server-side scripting.
   • Examples include e-commerce sites, social media platforms, and cloud-based tools.
2. Web Testing Types:
   • Functional Testing: Validates application features like navigation and user authentication.
   • Usability Testing: Ensures intuitive design and smooth user experience.
   • Compatibility Testing: Checks functionality across browsers, devices, and operating systems.
   • Performance Testing: Assesses load handling, speed, and scalability.
   • Security Testing: Detects vulnerabilities like XSS and SQL injection.
   • Accessibility Testing: Ensures compliance with accessibility standards.
   • Regression Testing: Verifies updates haven’t broken existing features.
3. Responsive and Cross-Browser Testing:
   • Confirms consistent behavior across browsers and devices, including mobile, tablet, and desktop.
4. Performance and Security:
   • Tools like Google Lighthouse or JMeter evaluate speed and server response.
   • Security checks focus on common threats and compliance with standards like OWASP.
