For example, Cyclomatic Complexity is adept at spotting methods containing a high degree
of conditional logic, which, conseqently, can be replaced with polymorphism as elaborated
in Martin Fowler's seminal work, Refactoring with the Replace Conditional with Polymorphism
pattern. Additionally, excessively deep hierarchy trees create problematic testing targets, which
can be broken out into separate objects with Fowler's Replace Inheritance with Delegation and
Collapse Hierarchy patterns. Fan-In and Fan-Out are quite effective at pinpointing brittle code,
which can be refactored into a more stable state with a plethora of patterns including
Extract Hierarchy and Extract Class. The knowledge of how to effectively spot smelly code and
replace it with proven patterns will ultimately lead to a more stable, maintainable and elegant code base.
