I want to suggest
const headersCopy = res.getHeaders();
// eslint-disable-next-line no-restricted-properties
const expected = {
'x-test-header': 'testing',
'x-test-header2': 'testing',
'set-cookie': cookies,
'x-test-array-header': arrayValues
};
Object.setPrototypeOf(expected, null)
assert.deepStrictEqual(headersCopy, expected);And a question, why is headersCopy.__proto__ === undifined?
Also headersCopy.hasOwnPropert === undifined so the API is wrong it says the return value is an Object

headersCopy.__proto__ === undifined?
Because, as you noted, headersCopy has a null prototype, and therefore the __proto__ getter inherited from Object.prototype is missing.
Also

It’s still an object, it just doesn’t inherit from Object.prototype; if you have suggestions on how to improve the docs for this, sure.

In my books it's not an Object if headersCopy instanceof Object === false 🤷♂️

test-http-mutable-headers uses assert.deepEqual() in three places but appears to only needs it in two of them. Replace one with assert.deepStrictEqual() and remove linting exception.

This does not land cleanly in LTS. Please feel free to manually backport. Please also feel free to replace the backport request label with do-not-land if it shouldn't land |

@MylesBorins If #10805 gets backported, I can backport this after that lands. |
