为什么在对 firebase 安全规则进行单元测试时出现“未实施”错误？

Question

我正在编写 firebase 存储安全规则，并使用“@firebase/rules-unit-testing”对它们进行单元测试。运行测试时，出现以下错误：

Not Implemented

      at node_modules/@firebase/rules-unit-testing/src/impl/rules.ts:64:11
      at step (node_modules/@firebase/rules-unit-testing/dist/index.cjs.js:74:23)
      at Object.next (node_modules/@firebase/rules-unit-testing/dist/index.cjs.js:55:53)
      at fulfilled (node_modules/@firebase/rules-unit-testing/dist/index.cjs.js:45:58)
      at tryCallOne (node_modules/promise/lib/core.js:37:12)
      at node_modules/promise/lib/core.js:123:15
      at flush (node_modules/asap/raw.js:50:29)

我目前唯一的单元测试应该是确认用户不能删除文件。

这是我的代码：

import {
  assertFails,
  assertSucceeds,
  initializeTestEnvironment,
  RulesTestEnvironment,
} from "@firebase/rules-unit-testing";
import {
  deleteObject,
  ref,
  uploadBytes,
} from "firebase/storage";
import * as fs from "fs";
const PROJECT_ID = "iurn-973d0";
let testEnv: RulesTestEnvironment;

describe("Firebase storage security rules", () => {
  beforeAll(async () => {
    testEnv = await initializeTestEnvironment({
      projectId: PROJECT_ID,
      firestore: {
        rules: fs.readFileSync(__dirname + "/../storage.rules", "utf-8"),
        host: "127.0.0.1",
        port: 9199,
      },
    });
  });
  beforeEach(async () => {
    if(!testEnv) return
    testEnv.clearStorage();
  });

  it("DOES NOT allow deletion", async () => {
    if(!testEnv) return
    const storage = testEnv.authenticatedContext("user123").storage();
    await testEnv.withSecurityRulesDisabled(async (context) => {
      await uploadBytes(ref(context.storage(), "hi.jpg"), require("../assets/images/placeholder.png"))
    })
    expect(assertFails(deleteObject(ref(storage, "hi.jpg")))).resolves.toBeTruthy()
  })

  afterAll(async () => {
    if(!testEnv) return
    testEnv.cleanup();
  });
});

“未实施”错误很可能是由于“@firebase/rules-unit-testing”库与您正在使用的 Firebase SDK 之间的版本不匹配引起的。

确保您使用的是与您的 Firebase SDK 版本兼容的最新版本的“@firebase/rules-unit-testing”。您可以在“@firebase/rules-unit-testing”文档中查看兼容性矩阵。

如果您已经确定版本兼容，请尝试将您的 Firebase SDK 和“@firebase/rules-unit-testing”库更新到最新版本。

此外，您可以尝试在代码中添加一些调试日志记录，以查看错误发生的位置。你也可以尝试在单元测试环境之外运行你的代码，看看你是否得到同样的错误。
