Unit testing verifies that the smallest entity can function correctly when isolated from the rest of the codes/units. A unit is the smallest entity which can independently exist, e.g.

These UTPs are executed to eliminate bugs at code level or unit level. In the V-Model, Unit Test Plans (UTPs) are developed during module design phase. The following are the typical phases of validation in the V-Model, though they may be known by other names.

In the V-model, each stage of verification phase has a corresponding stage in the validation phase. The unit test design is developed in this stage.

The low level design document or program specifications will contain a detailed functional logic of the module, in pseudocode: The designed system is broken up into smaller units or modules and each of them is explained so that the programmer can start coding directly. The module design phase can also be referred to as low-level design. The integration testing design is carried out in the particular phase. The baseline in selecting the architecture is that it should realize all which typically consists of the list of modules, brief functionality of each module, their interface relationships, dependencies, database tables, architecture diagrams, technology details etc. The phase of the design of computer architecture and software architecture can also be referred to as high-level design. The documents for system testing are prepared. Other technical documentation like entity diagrams, data dictionary will also be produced in this phase.

It may also hold example business scenarios, sample windows and reports to aid understanding. This document contains the general system organization, menu structures, data structures etc. The software specification document which serves as a blueprint for the development phase is generated. A resolution is found and the user requirement document is edited accordingly. If any of the requirements are not feasible, the user is informed of the issue. They figure out possibilities and techniques by which the user requirements can be implemented. Systems design is the phase where system engineers analyze and understand the business of the proposed system by studying the user requirements document. There are different methods for gathering requirements of both soft and hard methodologies including interviews, questionnaires, document analysis, observation, throw-away prototypes, use case and static and dynamic views with users. The user acceptance tests are designed in this phase. The users carefully review this document as this document would serve as the guideline for the system designers in the system design phase. It is used by business analysts to communicate their understanding of the system to the users. The user requirements document will typically describe the system's functional, interface, performance, data, security, etc. Usually, the users are interviewed and a document called the user requirements document is generated. However it does not determine how the software will be designed or built. This phase is concerned with establishing what the ideal system has to perform. In the requirements analysis phase, the first step in the verification process, the requirements of the system are collected by analyzing the needs of the user(s).
