Difference between Agile Testing and V-Model Testing

1. Agile Testing : Agile Testing is the type of software testing that involves all members of the project team, special experts and testers. In agile testing work together, testing is not a different phase and testing is performed along with development phases that includes requirements, design, coding and generation of test cases. It takes place alongside the Software Development Life Cycle (SDLC). 2. V-Model Testing : V-Model testing is the type of software testing that takes place once the development process is fully complete or almost complete. In this, processes of development and testing are kept quite separate. It does not contain any iteration approach. It is less reliable as compared to agile testing. 
Difference between Agile Testing and V-Model Testing :

S.No.	AGILE TESTING	V-MODEL TESTING
1.	It takes place alongside the development phase.	It takes place after the full completion of development phase.
2.	In this, development team and testing team work together.	In v testing, development team and testing team work are separate.
3.	In this, acceptance testing is carried out after every iteration.	In this, acceptance testing is carried out only in the end.
4.	It approaches to achieve working product / application, at the end of each iteration.	It does not contain any iteration approach.
5.	It mandates customer interaction on a regular basis.	It does not mandates customer interaction on a regular basis.
6.	It is more suitable for the projects where requirements change rapidly.	It is suitable where requirement changes are almost none.
7.	In this, testing is not a separate phase.	In this, testing is a separate phase.
8.	It tests each module after its development.	It tests whole software together.
9.	Agile is an iterative and incremental software development approach that emphasizes on flexibility, customer satisfaction, and delivering a working product quickly.	V-Model is a linear sequential software development approach that emphasizes on the planning, testing, and verification stages.
10.	Agile testing is a continuous process that involves testing early and frequently throughout the development lifecycle.	V-Model testing is a methodical process that involves testing at every stage of the development lifecycle.
11.	Agile testing is more suited for complex projects where requirements are not fully defined and may change frequently.	V-Model testing is more suited for projects with clearly defined requirements and stable scope.
12.	Agile testing involves collaboration and communication among team members, customers, and stakeholders.	V-Model testing is more formal and involves strict adherence to the predefined process and documentation.
13.	Agile testing focuses on continuous improvement and feedback loops, with a goal of delivering a working product quickly.	V-Model testing focuses on ensuring that each stage of the development lifecycle is completed successfully before moving on to the next stage.
14.	Agile testing uses automated testing tools to ensure faster feedback and better quality.	V-Model testing uses a combination of manual and automated testing tools to ensure the software meets the defined requirements.
