运行 Firebase 函数测试时“路径”中的类型错误

Question

我正在为谷歌云功能编写测试，该功能会将一些信息写入 Firestore 数据库。 测试使用firebase-functions-test和 jest。 我正在编写的函数在部署时成功运行，但是当我尝试运行测试时，我得到：

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type object

      at GrpcClient.loadProto (node_modules/google-gax/src/grpc.ts:182:23)
      at new FirestoreClient (node_modules/@google-cloud/firestore/build/src/v1/firestore_client.js:113:32)
      at ClientPool.Firestore._clientPool.pool_1.ClientPool [as clientFactory] (node_modules/@google-cloud/firestore/build/src/index.js:319:26)
      at ClientPool.acquire (node_modules/@google-cloud/firestore/build/src/pool.js:81:35)
      at ClientPool.run (node_modules/@google-cloud/firestore/build/src/pool.js:155:29)
      at Firestore.request (node_modules/@google-cloud/firestore/build/src/index.js:885:33)
      at WriteBatch.commit_ (node_modules/@google-cloud/firestore/build/src/write-batch.js:450:14)

我的功能：

const admin = require('firebase-admin');
const functions = require('firebase-functions');
const db = admin.firestore();

const saveCheckup = functions.pubsub.topic('save-test').onPublish((message) => {
  const {url, ...dataToSave} = message.attributes;

  let current = db.collection('current').doc(url);
  current.set(dataToSave, {merge: true})

  return true;
});

module.exports = saveCheckup;

我的测试：

import * as admin from 'firebase-admin';

const testEnv = require('firebase-functions-test')(
  {
    databaseURL: "https://my-project.firebaseio.com",
    projectId: 'my-project',
    storageBucket: 'my-project.appspot.com'
  }, "./my-project-firebase-adminsdk.json"
);


describe('saveCheckup', () => {
  let adminStub, saveCheckup;

  beforeAll(() => {
    adminStub = jest.spyOn(admin, "initializeApp");
    saveCheckup = require('../functions/save_checkup');
  });

  afterAll(() => {
    adminStub.mockRestore();
    testEnv.cleanup();
    admin.database().ref("current").remove();
  });

  it("should save the user", async () => {
    const wrapped = testEnv.wrap(saveCheckup);

    await wrapped({attributes: {
      date: "test date",
      url: "testurl",
      status: "200"
    }});

    const record = await admin.database().ref('/current/testurl').once('value');
    expect(record.val()).toHaveProperty("status", "200");
  })
});

更新：我们无法解决这个问题，最终只是为 firestore 编写离线测试。

您发布的错误输出显示错误位于 Google Firebase 节点模块文件中。 它甚至显示行和字符位置：

at new FirestoreClient (node_modules/.../v1/firestore_client.js:113:32)
//                                             Error location here ^

如果您尝试在本地部署，请阅读以下内容： https : //firebase.google.com/docs/hosting/deploying并根据您的情况按照说明进行操作。

在根目录添加一个“jest.config.js”，将以下代码保存到文件中

module.exports = {
    testPathIgnorePatterns: ['lib/', 'node_modules/'],
    moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'json', 'node'],
    testEnvironment: 'node'
};
