Testing question (No.6)

Q: What is a test scenario?
A: The terms “test scenario” and “test case” are often used synonymously.
Test scenarios are test cases, or test scripts, and the sequence in which they are to be executed.
Test scenarios are test cases that ensure that business process flows are tested from end to end.
Test scenarios are independent tests, or a series of tests, that follow each other, where each of them dependent upon the output of the previous one.
Test scenarios are prepared by reviewing functional requirements, and preparing logical groups of functions that can be further broken into test procedures.
Test scenarios are designed to represent both typical and unusual situations that may occur in the application.
Test engineers define unit test requirements and unit test scenarios. Test engineers also execute unit test scenarios.
It is the test team that, with assistance of developers and clients, develops test scenarios for integration and system testing.
Test scenarios are executed through the use of test procedures or scripts.
Test procedures or scripts define a series of steps necessary to perform one or more test scenarios.
Test procedures or scripts may cover multiple test scenarios.

Q: 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, walk-throughs and inspection meetings. You CAN learn to do verification, with little or no outside help. Get CAN get free information. Click on a link!

Q: 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.

Q: What is a walk-through?
A: A walk-through is an informal meeting for evaluation or informational purposes. A walk-through 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 walk-throughs is to ensure the code fits the purpose.
Walk-throughs also offer opportunities to assess an individual’s or team’s competency.

Q: 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 excessive use of rules can stifle both productivity and creativity. Peer reviews and code analysis tools can be used to check for problems and enforce standards.

Q: 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. Good internal 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.

Q: 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 phases like initial concept, requirements analysis, functional design, internal design, documentation planning, test planning, coding, document preparation, integration, testing, maintenance, updates, re-testing and phase-out.
