Identifying code smells

Benjamin Bischoff

Are hidden 'bloaters' and 'change preventers' sabotaging your architecture? Learn to spot these foundational code smells to mitigate technical debt and write highly testable, scalable software.

#1 about 4 min

Defining code smells and identifying deeper system problems

Setting the scope of code smells as surface-level indicators of bad design helps teams communicate efficiently and maintain testable code.

#2 about 7 min

Identifying bloater smells like long methods and classes

Breaking down oversized components and replacing primitive obsessions with custom types improves code readability and validation.

#3 about 5 min

Spotting common object-oriented programming abusers in applications

Avoiding misused object-oriented mechanisms like excessive switch statements or passing down unneeded behavior ensures proper design structure.

#4 about 4 min

Handling change preventers that hinder ongoing software development

Removing divergent change and shotgun surgery problems makes scaling code architectures significantly easier.

#5 about 4 min

Removing dispensable code layers and unnecessary structural elements

Eliminating lazy classes, dead code, and speculative generality prevents codebases from accumulating useless complexity.

#6 about 4 min

Addressing couplers that create inappropriate intimacy between classes

Fixing feature envy, message chaining, and middleman classes reduces dangerous tight coupling between independent modules.

#7 about 1 min

Tackling code smells during routine peer code reviews

Integrating code smell identification directly into development workflows ensures persistent adherence to clean architecture principles.
