Currently Rails/Validation does not cover the validation helper validates_comparison_of.

Expected behavior

For a model with the following validations:

  validates_presence_of :start_at, :end_at
  validates_comparison_of :end_at, greater_than: :start_at

Both validation helpers raise an error if Rails/Validation is Enabled.

Actual behavior

Only validates_presence_of triggers an error.

Steps to reproduce the problem

Add the old-style attribute validation macro for comparison to a model.

  validates_comparison_of :end_at, greater_than: :start_at

Run rubocop.
