@nice-labs/chai-bytes

A Chai plugin providing equalBytes assertions for comparing byte arrays (such as Uint8Array).

Forked from

Usage

``typescript
import { expect, assert, use } from 'chai'
import { chaiBytes } from 'chai-bytes'

use(chaiBytes)

const bytes = Uint8Array.of(0x01, 0x02, 0x03, 0x04, 0x05)

// BDD style
expect(bytes).to.equalBytes('0102030405')

// Assert style
assert.equalBytes(bytes, [0x01, 0x02, 0x03, 0x04, 0x05], 'should match bytes')
`

Supported Expected Values

The equalBytes assertion accepts:

- Hex strings: e.g., 'C0FFEE'
- Arrays: e.g., [1, 2, 3]
- Array-like objects: Any object with a length property and numeric indices (including Uint8Array)

If the expected value is not one of these, a TypeError` is thrown.
