Generate RSpec subjects/lets using Rantly

[thedrow]

Is there a way to parametrize subjects/lets using Rantly?

[abargnesi]

You can return rantly data from rspec's let and subject methods for use in your tests.

let example

require 'rantly'

describe 'Rspec let with rantly' do
  let(:random_string) do
    Rantly { string }
  end

  it 'is a String' do
    expect(random_string).to be_a String
  end
end

subject example

require 'rantly'

describe 'Rspec subject with rantly' do
  subject do
    Rantly { integer }
  end

  it 'is a Number' do
    expect(subject).to be_an Integer
  end
end

I know I can, but I want to be able to run the tests multiple times. I managed to do it without the RSpec integration.

@thedrow Could you provide an example of what you have done outside of the rspec integration?

You can also run each property test based on the RANTLY_COUNT environment variable. See here.

I no longer have access to the code. I just copy/pasted the blocks around.
As far as I understand from the documentation Rantly { integer } will only generate one example.

In order to utilize the rspec integration you have to use:

property_of {
  integer
}.check { |i|
  assert(i.is_a?(Integer), "integer property did not return Integer type")
}
