Getting Started (WIP)

A Basic Example

Suppose we want to create a class that checks if a number is a positive number or not.

Create a spec file spec/positive_spec.rb

require 'rast'

rast Positive do
  spec 'Is Positive Example' do
    execute { |number| subject.positive?(number) }
  end
end

Create a spec configuration spec/rast/positive_spec.yml

specs:
  Is Positive Exaple:
    variables: {number: [-1, 0, 1]}
    outcomes: {true: 1}

The class to test:

# positive.rb
class Positive
  def positive?(number)
    number > 0
  end
end

Running the test:

$ rspec -fd spec/examples/positive_spec.rb

Test result:

Positive: #positive?
  [false]=[number: -1]
  [false]=[number: 0]
  [true]=[number: 1]
