Are collection matchers work with objects? about spectator HOT 2 CLOSED

You're probably looking for match_array instead of contain_exactly.

contain_exactly expects a list of arguments, that is, they aren't already in a list. match_array expects a list as the argument.

The difference:

values = [1, 2, 3]
expect(values).to contain_exactly(1, 2, 3) # Not an array
expect(values).to match_array([1, 2, 3]) # Already an array

from spectator.

Ahah, that was dumb of me, I forgot that I needed to pass an argument list 😅. Now it works like a charm:

it "contains valid nodes" do
  expect(described_class.new(nodes).to_a).to contain_exactly(*nodes)
end
