V-MODEL : is a method that includes testing and validation alongside each development phase.It creates a structure like the letter 'V,' which includes various phases
PHASES OF V-MODEL :
REQUIREMENT ANALYSIS : Requirement needs to be cured from the customer's perspective. These phases include proper communication with the customer to understand their requirements. we use an acceptance test design planning which is done at the time of business requirement it will be used as an input for acceptance testing.
SYSTEM DESIGN : structure of the software is planned out. The team develops both the high-level design and detailed design.
ARCHITECTURAL DESIGN : Specifications are comprehended and designed. Usually, several technical approaches are put out, and the ultimate choice is made after considering both the technical and financial viability.
MODULE DESIGN : The comprehensive internal design for every system module. Compatibility between the design and other external systems as well as other modules in the system architecture is crucial. Unit tests are a crucial component of any development process since they assist in identifying and eradicating the majority of mistakes and flaws at an early stage.
CODING PHASE : Developers write the code based on the design created in the previous phase.The Coding step involves writing the code for the system modules that were created during the Design phase. The system and architectural requirements are used to determine which programming language is most appropriate.
