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"

    Missing top-level class documentation comment.
    Open

    class SignedUpTeam < ApplicationRecord
    Severity: Minor
    Found in app/models/signed_up_team.rb by rubocop

    This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, or constant definitions.

    The documentation requirement is annulled if the class or module has a "#:nodoc:" comment next to it. Likewise, "#:nodoc: all" does the same for all its children.

    Example:

    # bad
class Person
  # ...
end

# good
# Description/Explanation of Person class
class Person
  # ...
end

    Use a guard clause instead of wrapping the code inside a conditional expression.
