Cognitive Complexity

Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

A method's cognitive complexity is based on a few simple rules:

  • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
  • Code is considered more complex for each "break in the linear flow of the code"
  • Code is considered more complex when "flow breaking structures are nested"

The NPath complexity of a method is the number of acyclic execution paths through that method. A threshold of 200 is generally considered the point where measures should be taken to reduce complexity.

Example:

class Foo {
      function bar() {
          // lots of complicated code
      }
  }

The method normalizeAttributes() has a Cyclomatic Complexity of 22. The configured cyclomatic complexity threshold is 10.

Complexity is determined by the number of decision points in a method plus one for the method entry. The decision points are 'if', 'while', 'for', and 'case labels'. Generally, 1-4 is low complexity, 5-7 indicates moderate complexity, 8-10 is high complexity, and 11+ is very high complexity.

Example:

// Cyclomatic Complexity = 11
  class Foo {
  1   public function example() {
  2       if ($a == $b) {
  3           if ($a1 == $b1) {
                  fiddle();
  4           } elseif ($a2 == $b2) {
                  fiddle();
              } else {
                  fiddle();
              }
  5       } elseif ($c == $d) {
  6           while ($c == $d) {
                  fiddle();
              }
  7        } elseif ($e == $f) {
  8           for ($n = 0; $n < $h; $n++) {
                  fiddle();
              }
          } else {
              switch ($z) {
  9               case 1:
                      fiddle();
                      break;

                  default:
                      fiddle();
                      break;
