Cyclomatic Complexity

Checks the complexity of methods using McCabe simplified cyclomatic complexity check. Complexity levels can be customised using thresholds property.

Configuration

{
    "type": "CyclomaticComplexity",
    "props": {
        "thresholds": [
            {
                "severity": "INFO",
                "complexity": 6
            },
            {
                "severity": "WARNING",
                "complexity": 11
            },
            {
                "severity": "ERROR",
                "complexity": 21
            }
        ]
    }
}

In general, for function level complexity:

The following function has a complexity score of 8.

public function test() {
    var a = 1;
    if (a == 1) {
        for (i in 0 ... 10) {
            for (j in 0 ... 100) {
                if (i == 5) {
                    if (j == 50) {
                        trace(j);
                    }
                }
            }
        }
    }

    switch (a) {
        case 1:
            trace(1);
        case 2:
            trace(2);
        default:
            trace("default");
    }
}

Function "test" is too complex (score: 8)
