Using Seams to Enable Testability and Expand Capabilities

Seams are strategic points in code where behavior can be modified without altering the existing implementation. They are crucial for introducing changes safely, enabling testing, and incrementally refactoring legacy systems. This course explores functional and object seams and their role in improving code maintainability in Scala.
