What is Web Testing?

• Web testing is the name given to software testing that focuses on web applications. 
• Complete testing of a web-based system before going live can help address issues before the system is revealed to the public.
• Issues such as the security of the web application, the basic functionality of the site, its accessibility to handicapped users and fully able users, as well as readiness for expected traffic and number of users and the ability to survive a massive spike in user traffic, both of which are related to load testing.

Web security testing

• Web security testing tells us whether Web based applications requirements are met when they are subjected to malicious input data.

Verification and Validation.

Verification and Validation is independent procedures that are used together for checking that a product, service, or system meets requirements and specifications and that it fulfills its intended purpose.

 

Verification:

• Verification is the process of checking or testing items, including software, for conformance and consistency by evaluating the results against pre-specified requirements.
• Verification: "Are we building the product right"
• The software should conform to its specification.
• It is intended to check that a product service, or system meets a set of initial design requirements, specifications, and regulations.

Validation:

• Validation looks at the system correctness – i.e. is the process of checking that what has been specified is what the user actually wanted.
• Validation: “Are we building the right product?”
• The software should do what the user really requires.
• It is intended to check that development and verification procedures for a product, service, or system result in a product, service, or system that meets initial requirements, specifications, and regulations.
