Software QA/Testing
Glossary and Technical FAQs

Q1. What is verification?
A: Verification ensures the product is designed to deliver all functionality to the customer; it typically involves reviews and meetings to evaluate documents, plans, code, requirements and specifications; this can be done with checklists, issues lists, walkthroughs and inspection meetings. You CAN learn to doverification, with little or no outside help. Get CAN get free information. Click on a link!
Q2. What is validation?
A: Validation ensures that functionality, as defined in requirements, is the intended behavior of the product; validation typically involves actual testing and takes place after verifications are completed.
Q3. What is a walkthrough?
A: A walkthrough is an informal meeting forevaluation or informational purposes. A walkthrough is also a process at an abstract level. It's the process of inspecting software code by following paths through the code (as determined by input conditions and choices made along the way). The purpose of code walkthroughs is to ensure the code fits the purpose. Walkthroughs also offer opportunities to assess an individual's or team's competency.
Q4. Whatis an inspection?
A: An inspection is a formal meeting, more formalized than a walkthrough and typically consists of 3-10 people including a moderator, reader (the author of whatever is being reviewed) and a recorder (to make notes in the document). The subject of the inspection is typically a document, such as a requirements document or a test plan. The purpose of an inspection is to findproblems and see what is missing, not to fix anything. The result of the meeting should be documented in a written report. Attendees should prepare for this type of meeting by reading through the document, before the meeting starts; most problems are found during this preparation. Preparation for inspections is difficult, but is one of the most cost-effective methods of ensuring quality, since bugprevention is more cost effective than bug detection.
Q5. What is quality?
A: Quality software is software that is reasonably bug-free, delivered on time and within budget, meets requirements and expectations and is maintainable. However, quality is a subjective term. Quality depends on who the customer is and their overall influence in the scheme of things. Customers of a software developmentproject include end-users, customer acceptance test engineers, testers, customer contract officers, customer management, the development organization's management, test engineers, testers, salespeople, software engineers, stockholders and accountants. Each type of customer will have his or her own slant on quality. The accounting department might define quality in terms of profits, while an end-usermight define quality as user friendly and bug free.
Q6. What is good code?
A: A good code is code that works, is free of bugs and is readable and maintainable. Organizations usually have coding standards all developers should adhere to, but every programmer and software engineer has different ideas about what is best and what are too many or too few rules. We need to keep in mind that excessiveuse of rules can stifle both productivity and creativity. Peer reviews and code analysis tools can be used to check for problems and enforce standards.
Q7. What is good design?
A: Design could mean to many things, but often refers to functional design or internal design. Good functional design is indicated by software functionality can be traced back to customer and end-user requirements. Goodinternal design is indicated by software code whose overall structure is clear, understandable, easily modifiable and maintainable; is robust with sufficient error handling and status logging capability; and works correctly when implemented.
Q8. What is software life cycle?
A: Software life cycle begins when a software product is first conceived and ends when it is no longer in use. It includes...
