Software engineering

A place to change behaviour without editing there

In software engineering a seam is a place where you can alter a program's behaviour without editing in that place. Michael Feathers coined the term in Working Effectively with Legacy Code for the points (an interface, a subclass, a link-time or object substitution) at which different code can be slipped in, most often to pull a stubborn, tangled module under test without rewriting it. The referent is an abstraction boundary in a codebase, a lever for change, and has nothing physical in common with a bed of coal or a line of stitching beyond the shared image of a joint you can work along.[1]

Unit
The enabling point at which behaviour can be substituted, and its enabling mechanism
Recovery means
Not applicable
Measured by
Identified by locating substitution points (interfaces, seams for test doubles) and the enabling point that controls each
