Code complexity
Code complexity
It is the cyclomatic complexity, also known as McCabe metric. Whenever the control flow of a function splits, the complexity counter gets incremented by one. Each function has a minimum complexity of 1.
Or. A measurement of the intricacy of a program module based on the number of repetitive cycles or loops that are made in the program logic. It is used as a general measure of complexity for software quality control as well as to determine the number of testing procedures.
Why care?
- How many outcomes for a given piece of code?
- Outcomes create behaviors. Each is a possible regression.
How is it calculated?
public void process(Car myCar){ // +1 if(myCar.isNotMine()){ // +1 return; // +1 } car.paint("red"); car.changeWheel(); while(car.hasGazol() && car.getDriver().isNotStressed()){ // +2 car.drive(); } return; }
How to track this on Sonar?
Each project has a complexity analysis tool. ie: kettle-core.
