尝试使用模拟器测试 Firestore 安全规则时总是发生超时错误

Question

我尝试使用模拟器测试 Firestore 安全规则，但总是出现超时错误... 如果您有同样的现象或有解决办法，请告诉我。

测试结果

启动模拟器

% firebase serve --only firestore

运行测试

% yarn test
yarn run v1.19.2
$ jest
 FAIL  tests/firestore.test.ts (7.123s)
  Firestore Security Rule
    ✕ sample1 (5044ms)

  ● Firestore Security Rule › sample1

    : Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.Error:

环境

※Firestore 安全规则因样本而允许一切

■firestore.test.ts

import * as firebase from "@firebase/testing";
import * as fs from "fs";

const PROJECT_ID = "firestore-rule-test";
const RULES_PATH = "firestore.rules";

// Create Firestore app with auth
const createAuthApp = (auth?: object): firebase.firestore.Firestore => {
  return firebase
    .initializeTestApp({ projectId: RULES_PATH, auth: auth })
    .firestore();
};

const usersRef = (db: firebase.firestore.Firestore) => db.collection("user");

describe("Firestore Security Rule", () => {
  beforeAll(async () => {
    await firebase.loadFirestoreRules({
      projectId: PROJECT_ID,
      rules: fs.readFileSync(RULES_PATH, "utf8")
    });
  });

  afterEach(async () => {
    await firebase.clearFirestoreData({ projectId: PROJECT_ID });
  });

  afterAll(async () => {
    await Promise.all(firebase.apps().map(app => app.delete()));
  });

  test("sample1", async () => {
    const db = createAuthApp();
    const user = usersRef(db).doc("test");
    await firebase.assertSucceeds(user.set({ name: "John" }));
    await firebase.assertSucceeds(user.get());
  });
});;

Answer 1

在您的createAuthApp() 函数中，您正在使用RULES_PATH 的项目ID 初始化测试应用程序，但在您的测试中，您正在使用PROJECT_ID 的项目ID 加载安全规则。

变化

.initializeTestApp({ projectId: RULES_PATH, auth: auth })

到

.initializeTestApp({ projectId: PROJECT_ID, auth: auth })

应该可以解决您的问题。

如果它不能解决问题，您可以使用 --testTimeout=<number of ms> 将 Jest 超时更改为 5 秒以上，以便让测试有更多时间完成。

最后，为了清楚起见，考虑将createAuthApp 重命名为createFirestoreInstance，因为“创建身份验证”意味着与FirebaseAuth 类有关。
