rspec include matcher fails with equal arrays

Question

I'm testing the active scope of SystemCommission, I have the following test:

  expected = [active, no_starting, no_ending]
  expect(SystemCommission.active.map(&:id)).to include expected.map(&:id)

it fails with:

Failure/Error: expect(SystemCommission.active.map(&:id)).to include expected.map(&:id)
       expected [1, 2, 3] to include [1, 2, 3]

I had to use the ids because it wasn't matching the objects.

any clues?

Answer 1

The array [1, 2, 3] does not include [1, 2, 3]

To make that pass it would look something like: [1, 2, 3, [1, 2, 3]]

splat your array:

expect(SystemCommission.active.map(&:id)).to include *expected.map(&:id)
