White box testing
White box testing
Testing for each program path, each loop ad conditions, input ranges, events fast occurring events and constraints ( memory , energy requirement and response times of function, routines and drivers).

Software validation
Software validation
Validation means that software must be according to the specifications and must show behavior as expected in all the events, condition's and times specified and all components must meet constraints ( memory, energy requirement, and response times of functions, routines and drivers).

Requirement analysis
Requirement analysis
The first step in the software development process. Firstly, general statements are made and then from these the technical concrete specification, are obtained. Later, the requirements from all software components, data , control and process specified are ascertained.

Object Oriented Development Model
Object Oriented Development Model
A process of developing software by first partitioning software into components and also using reusable components by adapting and the each component is composed of objects that are reusable. Reusing an object is by direct adoption, inheritance and overriding states and behavior.
