Agile Model: Agile Model is the software development model in which the development and testing process carries on simultaneously. In this model, both development-related processes and testing-related processes are parallel. This model provides the facility for more interaction between the development team, testing team, and end-users.
V-Model: V-Model is the software development model in which testing takes place once the development process is fully complete or almost complete. The V-Model development and testing process are kept quite separate. It is not as reliable as the Agile Model.
Difference between Agile Model and V-Model:
S. No. | Agile Model | V-Model |
---|---|---|
1. | It is a software development model in which development and testing are concurrent. | It is also a software development model but development and testing are not concurrent. |
2. | It consists of different sprints. | It has two phases-Verification and Validation. |
3. | Testing is easy as compared to V-model. | Testing is hard as compared to the Agile model. |
4. | It consists of total of five phases. | It consists of five verification and five validation phases. |
5. | Communication is easy between end users, the development team, and the testing team. | The development team and testing team don’t interact much with end users. |
6. | Developers and testers are dependent on each other. | Developers and testers are independent. |
7. | It is iterative. | It is not iterative. |
8. | It is incremental. | It is not incremental. |
9. | It is suitable for small or large projects where the work needs to be completed iteratively. | It is suitable for large projects where the work needs to be completed sequentially. |
10. | In Agile model, the coding and testing phase gains more focus than the design phase. | In V-model, the design phase gains more focus than the implementation phase. |
11. | In agile model, working software is available early as compared to V-model. | In V-model, working software takes time in comparison to the agile model. |
12. | It is a proactive model. | It is a reactive model. |
13. | It is more flexible compared to V-model. | This model is less flexible and more rigid compared to the agile model. |
14. | Relatively less testing cycle time than V-model because testing is done in parallel with the development. | Testing cycle time is more than the agile model. |
