Understanding the Difference between Waterfall Model and Agile Model in Software Testing

When it comes to software testing methodologies, the difference between the waterfall model and agile model lies in their approach to development and testing processes.

Waterfall Model:

The waterfall model follows a linear and sequential approach to software development and testing. In this model, each phase of the development cycle, including requirements gathering, design, implementation, testing, and deployment, is completed one after the other. Testing is usually done at the end of the development cycle in the waterfall model.

Agile Model:

On the other hand, the agile model is based on iterative and incremental development. It emphasizes collaboration, flexibility, and quick feedback loops. In the agile model, software development and testing are done in short cycles known as sprints. Testing is an integral part of each sprint, ensuring that quality assurance is maintained throughout the development process.

In summary, the key difference between the waterfall model and agile model in software testing is their approach to development and testing processes. While the waterfall model is linear and sequential, the agile model is iterative and flexible, with testing being an ongoing and integral part of the development cycle.
