metric quite similar to Relational Operator Coverage but it is much more general. It reports whether test cases occur which would expose the use of wrong operators and also wrong operands. It works by reporting coverage of conditions derived by substituting (mutating) the program's expressions with alternate operators, such as "-" substituted for "+", and with alternate variables substituted.
White Box Test Design Technique:
White Box Test Design Technique is a documented procedure to derive and select test cases based on an analysis of the internal structure of a component or system.
White-Box Testing is based on an analysis of internal workings and structure of a piece of software. It is a testing technique which assumes that the path of the logic in a program unit or component is known. It usually consists of testing paths, branch by branch, to produce predictable results. This technique is usually used during tests executed by the development team, such as Unit or Component testing.
Waterfall Model is a sequential software development model (a process for the creation of software) in which development is seen as flowing steadily downwards (like a waterfall) through the phases of requirements analysis, design, implementation, testing (validation), integration, and maintenance. To follow the waterfall model, one proceeds from one phase to the next in a purely sequential manner. In traditional waterfall model, testing comes at the fag end of the development process. No testing is done during requirements gathering phase, design phase and development phase.
Workflow Testing is scripted end-to-end testing which duplicates specific workflows which are expected to be utilized by the end-user.
Wide Band Delphi:
Wide Band Delphi is an expert based test estimation technique that aims at making an accurate estimation using the collective wisdom of the team members.
