How would you write Rspec code for Enumerable#any? ?

Like :

a = [1,2,43,54,6]
b = [6,77,11]
a.any? { |i| b.include i } # => true

Regards,
Arup Rakshit

it "checks if any a are included in b" do
  a = [1,2,43,54,6]
  b = [6,77,11]
  expect(a.any?{|i| b.include i}.to be_true
end

Here is a simple example:
----

cat enum_spec.rb

require 'rspec'

RSpec.describe "Test enumerable" do
  it "returns 'true'" do
    a = [1,2,43,54,6]
    b = [6,77,11]
    expect(a.any? { |i| b.include? i}).to eq(true)
  end

  it "returns 'false'" do
    a = [1,2,43,54]
    b = [6,77,11]
    expect(a.any? { |i| b.include? i}).to eq(false)
  end
end

rspec enum_spec.rb

..

However, 'minitest'[1] is also very good testing framework with the additional '+' that it comes with ruby by default. I've used both minitest and rspec. I didn't notice any differences between the two at core level. Rspec has a wide variety of additional gems and strong community. Maybe more advanced users would like to point out some differences between the two and when to use one over the other.

Hi All,

Thanks for your help. It works. But I though Rspec have some inbuilt method like _match_array_ kind of. Anyway it works.

Hi Arup,

From:
- File: README — Documentation for rspec-expectations (3.12.3)
- https://www.relishapp.com/rspec/rspec-expectations/v/3-0/docs/built-in-matchers

Collection membership
expect(actual).to include(expected)
expect(actual).to start_with(expected)
expect(actual).to end_with(expected)

Match Array
expect(actual).to match_array(expected)

Look at "contain_exactly" also...
