Creating an encrypted secret with libsodium in a Jest unit test fails: TypeError: unexpected type, use Uint8Array

Question

我想为 GitHub API 存储库秘密端点编码一个秘密。代码直接来自 docs:

const sodium = require('tweetsodium');

const key = "base64-encoded-public-key";
const value = "plain-text-secret";

// Convert the message and key to Uint8Array's (Buffer implements that interface)
const messageBytes = Buffer.from(value);
const keyBytes = Buffer.from(key, 'base64');

// Encrypt using LibSodium.
const encryptedBytes = sodium.seal(messageBytes, keyBytes);

// Base64 the encrypted secret
const encrypted = Buffer.from(encryptedBytes).toString('base64');

console.log(encrypted);

我使用 Jest 运行对此代码进行单元测试。使用 Jest，我得到一个 TypeError: unexpected type, use Uint8Array 错误。没有开玩笑，代码运行正常。

我想对我的代码进行单元测试。我怎样才能让它在 Jest 中运行？

这个GitHub issue解释错误：

As mentioned here, this looks like the testing framework has its own Buffer implementation that is not based on Uint8Array. All functions in TweetNaCl-js expect arguments to be Uint8Arrays and it checks for it here: https://github.com/dchest/tweetnacl-js/blob/master/nacl-fast.js#L2150

这显然是 jest 框架中的一个已知错误。你可以通过 jest-environment-uint8array 依赖并添加测试环境来解决它 package.json:

  "jest": {
    "testEnvironment": "jest-environment-uint8array",
    "testTimeout": 10000
  },
