Pattern: Unneeded method definition

Issue: -

Description

This rule checks for useless method definitions, specifically: empty constructors and methods just delegating to super.

This rule is marked as unsafe as it can trigger false positives for cases when an empty constructor just overrides the parent constructor, which is bad anyway.

Examples

# bad
def initialize
  super
end

def method
  super
end

# good - with default arguments
def initialize(x = Object.new)
  super
end

# good
def initialize
  super
  initialize_internals
end

def method(*args)
  super(:extra_arg, *args)
end
