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"

Cyclomatic complexity for aggregate_totals is too high. [14/11]
Open

  def aggregate_totals(row, group, total, options)
    return if options.blank?

    options.each_key do |c|
      grouping = options[c][:grouping]

This cop checks that the cyclomatic complexity of methods is not higher than the configured maximum. The cyclomatic complexity is the number of linearly independent paths through a method. The algorithm counts decision points and adds one.

An if statement (or unless or ?:) increases the complexity by one. An else branch does not, since it doesn't add a decision point. The && operator (or keyword and) can be converted to a nested if statement, and ||/or is shorthand for a sequence of ifs, so they also add one. Loops can be said to have an exit condition, so they add one.

Avoid when branches without a body.
Open

        when :total, :count, :min, :max

This cop checks for the presence of when branches without a body.

Example:

# bad

case foo
when bar then 1
when baz then # nothing
end

Example:

# good

case foo
when bar then 1
when baz then 2
end
