The V model describes the relationship between each phase of the software development cycle, and the testing phase. Our expert explains this methodology.
The shape of the V-model is very similar to the letter V. The validation and verification phases are represented by the left-hand sides.
WHEN TO USE A VMODEL
When the requirements and understanding of the software's functionality are clearly understood and defined at the beginning, a V-model can be a valuable tool in delivering high-quality software.
Communication and coordination can become difficult when working in large teams. The V model helps to ensure that everyone has a clear understanding about the project's goals and clearly defines the testing requirements for each stage.

V-Model Verification Phases
Verification is the process of verifying that product development processes meet requirements.
The verification phase includes several steps: system analysis, business requirement analysis, and software architecture design. Some of these steps include module design and coding.
The team will review the product requirements of the customer during the business requirement analysis phase.
System analysis involves the interpretation and analysis of business requirements by system engineers. This is accomplished by reviewing the user requirements document.
This is the stage where the team selects the software architecture. This stage is determined by the brief functionality and list of modules. It considers dependencies and table tables as well as architecture diagrams and technology details.
Module design is the stage where the development team disassembles the system and designs each module. This stage is also known as low-level design.
Now we can get to coding. Based upon product design and specifications, the development team selects a programming language. Code will be reviewed multiple times to ensure it is effective.

V-Model Validation Phases
Validation is testing and dynamic analysis to ensure the product meets customers' expectations.
During the unit testing stage, the team creates and executes unit test plans. These plans are used for finding errors in code and units.
Integration testing is the execution of integration tests plans that were developed during the architectural design phase. This is done to verify that groups, which were created and tested independently, can coexist and communicate with each other.
System testing is the execution of system tests plans that were developed during system design. These plans are prepared by client's business teams.
Acceptance testing is part of the V-model's business requirements analysis section. This involves testing the software product in a user environment to identify compatibility issues.
Principles for the V-Model
Quality assurance and testing are key principles in the V-model.
INTEGRATE TESTING THRU DEVELOPMENT
Testing shouldn't be done at the end. Testing should be part of every stage of the development process from requirements gathering to deployment.
PARALLEL TESTING WITH DEVELOPMENT
Each stage of development comes with its own testing phase. To support testing, activities are planned in parallel to development activities.
PREVENT DEFECTS
The V model emphasizes the importance of preventing and not fixing defects once they are found.
CONCISE AND DEVELOP CLEAR REQUIREMENTS
Clear, concise requirements are key to the V-model. Without a clear understanding of what the software does, it is difficult to develop effective tests and build high quality software.
COMBINE DEVELOPMENT & TESTING
The V_model doesn't distinguish between development and testing. It is important that developers and testers work together to ensure software conforms to quality standards.
Many advantages have the V-Model
Quality: The V-model increases the quality of software development. This is why there are less bugs and better software.
Reduced risks: The V model offers a clear path to development that facilitates risk management.
Increased efficiency: Collaboration among stakeholders and teams is encouraged by the V model. This allows for more efficient development, testing, and production.
Improved Communication
Test Enhancement: The V model puts a lot of emphasis on testing during the development process.
Documentation enhancement: The V-model requires detailed documentation at every stage of development. This allows for better code maintenance and record-keeping.
