Understanding Symptoms of Bad Code in Software Development
The symptoms of bad code - Robert C. Martin (Uncle Bob) 🔗
Symptoms of Bad Code
Identifying the symptoms of bad code can significantly affect software development efficiency. Key symptoms include:
- Rigidity: Making a change in one part of the code requires extensive modifications in many other areas, leading to a slow development process.
- Fragility: Making a small change can cause unexpected failures in unrelated parts of the code, resulting in unpredictable behavior and loss of confidence from managers and customers.
- Coupling: Strong dependencies between modules make it difficult to reuse code, as desirable parts are often intertwined with undesirable components, leading to inefficiency and complexity.
These issues highlight the importance of managing code dependencies to maintain quality and promote agile development.
What is rigidity in code?
Rigidity refers to a situation where a small change in the code necessitates widespread modifications in other areas, making the process cumbersome and time-consuming.
How does fragility manifest in software?
Fragility occurs when a minor change leads to failures in unrelated parts of the code, causing unpredictable behavior and raising concerns among managers and customers.
What is coupling in the context of bad code?
Coupling describes the degree to which different modules depend on one another. High coupling can result in difficulties in reusing code and maintaining the system, as changes in one module can affect many others.
