What is the relationship between defect density and code complexity?

What is the relationship between defect density and code complexity?

Defect density refers to the number of defects confirmed in software relative to the size of the software. Code complexity, on the other hand, measures how complicated the code is. Generally, as code complexity increases, defect density tends to increase as well.

Can you explain why more complex code leads to more defects?

Certainly! More complex code can be harder to understand and maintain, which increases the likelihood of errors during development. Additionally, complex interactions between different parts of the code can lead to unforeseen issues.

Are there any metrics to measure code complexity?

Yes, there are several metrics to measure code complexity, including Cyclomatic Complexity, Halstead Complexity, and Maintainability Index. Each of these provides insights into different aspects of code complexity.

How can I reduce code complexity?

You can reduce code complexity by following best practices such as refactoring, using design patterns, writing modular code, and ensuring proper documentation. Regular code reviews can also help identify complex areas that need simplification.
