How would you write Rspec code for Enumerable#any?

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

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.

Sorry, typo:

expect(a.any?{|i| b.include i}).to be_true

Hi Arup,

From:

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…
