import test from 'node:test'
import printAdjacent from 'print-adjacent'

test('Make sure one object is the same as another', () => {
  assert.deepStrictEqual(
    object1,
    object2,
    printAdjacent(
      ['EXPECTED', JSON.stringify(object2, null, 2)],
      ['ACTUAL', JSON.stringify(object1, null, 2)],
    ),
  )
})
