standard_assert

standard_assert is a Standard Library-like library for assertions in Ruby.
It is aimed at encouraging us to use assertion methods anywhere; Not only testing but also production.

Installation

Add this line to your application's Gemfile:

gem 'standard_assert'

And then execute:

$ bundle

Usage

Use Assert module with extend or include in classes or modules where you want to use assertion methods:

require 'standard_assert'

module MyMath
  extend ::Assert

  module_function

  def abs(num)
    assert_instance_of([::Float, ::Integer, ::Rational], num)
    num.positive? ? num : -num
  end
end

MyMath.abs('42')
#=> AssertionError: <"42"> was expected to be instance_of?
#   [<Float>, <Integer>, <Rational>] but was
#   <String>.
