Seamdriven

Seamdriven is a software development methodology that emphasizes the importance of seams in software design. A seam is defined as a place where you can alter behavior in your program without editing in that place. This concept was popularized by Michael Feathers in his book "Working Effectively with Legacy Code." The primary goal of seamdriven development is to create software that is more adaptable and easier to maintain, especially in the context of legacy systems.

In seamdriven development, developers focus on identifying and utilizing seams to make changes to the software without having to extensively rewrite or refactor existing code. This approach is particularly useful when dealing with large, complex systems where making changes directly can be risky and time-consuming. By leveraging seams, developers can introduce new features, fix bugs, or adapt the software to new requirements more efficiently.

The methodology encourages the use of techniques such as dependency injection, interface-based programming, and aspect-oriented programming to create seams that allow for flexible and modular code. This not only improves the maintainability of the software but also enhances its testability, as seams can be used to isolate and test individual components more effectively.

Overall, seamdriven development is a practical approach to managing the complexities of software development, particularly in legacy systems. By focusing on seams, developers can create more robust and adaptable software that can better withstand the challenges of evolving requirements and technological changes.
