AsyncQueue 無法持久寫入：TypeError：無法讀取未定義的屬性（讀取“toString”）

Question

我正在嘗試為我的 Firestore 規則編寫單元測試。 它松散地基於https://github.com/firebase/quickstart-testing/blob/master/unit-test-security-rules/test/firestore.spec.js

並遵循https://firebase.google.com/docs/firestore/security/test-rules-emulator

它有 3 個測試用例，其中 2 個通過。 第三個測試是用戶無法刪除文檔，但deleteDoc似乎會引發錯誤。

這是我的測試代碼

import {assertFails, assertSucceeds} from "@firebase/rules-unit-testing";
import firebase = require("@firebase/rules-unit-testing");
import fs = require("fs");
import {setDoc, deleteDoc} from "firebase/firestore";

const PROJECT_ID = "firestore-emulator-example";


describe("Rules test", function() {
  let env: firebase.RulesTestEnvironment;

  before(async () => {
  // Load the rules file before the tests begin
    const rules = fs.readFileSync("../firestore.rules", "utf8");
    env = await firebase.initializeTestEnvironment(
        {
          projectId: PROJECT_ID,
          firestore: {rules},
        }
    );
  });

  beforeEach(async () => {
  // Clear the database between tests
    await env.clearFirestore();
  });

  it("require users to log in before creating a profile", async () => {
    const userId = "alice";
    const context = env.authenticatedContext(userId);
    await assertSucceeds(
        setDoc(
            context.firestore().doc(`/privateProfiles/${userId}`),
            {}
        )
    );
  });

  it("edit only your own profile", async () => {
    const alice = "alice";
    const bob = "bob";
    const aliceContext = env.authenticatedContext(alice);
    const bobContext = env.authenticatedContext(bob);
    await assertSucceeds(
        setDoc(
            aliceContext.firestore().doc(`/privateProfiles/${alice}`),
            {}
        )
    );
    await assertFails(
        setDoc(
            bobContext.firestore().doc(`/privateProfiles/${alice}`),
            {}
        )
    );
  });

  it("can't directly delete a profile", async () => {
    const alice = "alice";
    const aliceContext = env.authenticatedContext(alice);
    const db = aliceContext.firestore();
    await assertSucceeds(
        setDoc(
            db.doc(`/privateProfiles/${alice}`),
            {"smth": 1}
        )
    );
    await assertFails(
        deleteDoc(
            db.doc(`/privateProfiles/${alice}`)
        )
    );
  });
});

完整代碼位於https://github.com/GustekDev/db-unit-tests-example

使用firebase emulators:exec./test.sh從內部functions目錄運行測試。

我做錯了什么，還是 Firebase 中的錯誤？

Answer 1

該問題已通過更改解決

assertSucceeds(setDoc(alice.firestore(), '/users/alice'), { ... })

到

assertSucceeds(setDoc(doc(alice.firestore(), '/users/alice'), { ... }))
