Solution

I tried to keep the solution in its simplest form. It's basically a file and a test file. I added the
Gemfile at the end for convenience.

The instructions only said that it must work for the same kind of carrousel, which is very specific
since other image searches show a different type of carrousel.

My focus was to reproduce the same result as the expected-array.json file and without making any
http requests. And of course the test suite which I want to elaborate a little:

• I think every test should have only 1 expect.
• Every test must have a clear goal, with only 1 scenario.

I think it is better appreciated in the following section:

let(:artwork_with_empty_extensions) { result["artworks"].select{|a| a["name"]=="Sunflowers"}.first}
describe 'extensions' do
    it "must be an Array, if present" do
        expect(artwork["extensions"]).to be_an Array
    end

    it "can't contain empty Strings" do
        expect(artwork["extensions"]).not_to include("")
    end

    it "should not be present if value is empty" do
        expect(artwork_with_empty_extensions).not_to include("extensions")
    end
end

There was an scenario where the extensions are not set, in the expected results the extensions were
not present, so I provided a specific scenario to the test so it can be properly tested.

To test

Just run

bundle install
ruby test.rb
