TL;DR: Avoid Accidental complexity and bureaucracy
Problems
- Accidental Complexity
- Readability
- Bijection Fault
Solutions
- Asign the responsibilities to real-world objects using the MAPPER
Context
A "red tape" code smell could relate to unnecessary complexity, bureaucracy, or excessive configuration that makes the codebase harder to understand or maintain.
Sample Code
Wrong
class VotingSystem:
def __init__(self, config):
self.config = config
def validate_voter(self, voter_id):
if self.config['voter_verification_enabled']:
# Code to verify the voter's identity goes here
def cast_vote(self, voter_id, candidate):
if self.config['voting_enabled']:
# Code to record the vote goes here
def generate_vote_report(self):
if self.config['generate_report']:
# Code to generate a voting report goes here
def audit_voting_system(self):
if self.config['audit_enabled']:
# Code to perform an audit of the voting system goes here
# ... other voting-related methods ...
# Usage
config = {
'voter_verification_enabled': True,
'voting_enabled': False,
'generate_report': False,
'audit_enabled': True
}
voting_system = VotingSystem(config)
# Voter validation, voting, report generation,
# and auditing are handled based on the configuration.
Right
class VoterVerification:
def verify_voter(self, voter_id):
# Code to verify the voter's identity goes here
class VotingMachine:
def cast_vote(self, voter_id, candidate):
# Code to record the vote goes here
class VoteReporter:
def generate_report(self):
# Code to generate a voting report goes here
class VotingAuditor:
def audit_voting_system(self):
# Code to perform an audit of the voting system goes here
# Usage
voter_verification = VoterVerification()
voting_machine = VotingMachine()
vote_reporter = VoteReporter()
voting_auditor = VotingAuditor()
# Voter verification, vote casting, report generation,
# and auditing are handled separately.

Some tools can guess you are bloating your objects with unnecessary responsibilities.

Conclusion
The red tape code smell is evident as developers need to navigate the complex configuration to determine which features are active.
This not only adds unnecessary complexity but also increases the likelihood of misconfigurations that could impact the integrity of your system.
