Quality Report

Quality Score

The quality score is a mark out of 10 for code quality. It is a blend of the complexity and method length metrics.

Complexity

The complexity metric is a measure of how difficult your code is to read and understand. It is based on these principles:

• Each break in the linear flow of the code makes it harder to understand
• When these flow-breaking structures are nested they are even harder to understand

Flow-breaking structures are things like conditionals, loops and complex series of logical operators.

Full details of how this metric is calculated are contained in the Cognitive Complexity: A new way of measuring understandability white paper by G. Ann Campbell of SonarSource.

Method Length

The method length metric is a measure of how long each method is on average. It is based on the number of nodes in the method's Abstract Syntax Tree.

It is better for methods to be concise and to do one thing, so this metric penalises overly long methods.
