我正在尝试测试我编写的firestore安全规则，但每次我试图运行我的测试时，我都得到超时错误。
在运行测试之前，我使用以下命令启动firestore模拟器:
❯ npm run firebase:run:emulator
> warzywniax@0.0.0 firebase:run:emulator
> cd firebase && firebase emulators:start --project=warzywniax --import=./seed --export-on-exit

看起来一切正常。我的firestore模拟器托管在127.0.0.1:8080下并且通过我的web浏览器访问这个模拟器没有任何问题。
在我运行任何测试之前，我在setupFilesAfterEnvjest hook上运行一些设置脚本。整个设置脚本如下所示:
import { initializeTestEnvironment, RulesTestEnvironment } from '@firebase/rules-unit-testing';
import firebase from 'firebase/compat/';
export let testEnvironment: RulesTestEnvironment;
export let guestUserContext: firebase.firestore.Firestore;
beforeAll(async () => {
testEnvironment = await initializeTestEnvironment({
firestore: {
host: '127.0.0.1',
port: 8080,
},
projectId: 'warzywniax',
});
guestUserContext = testEnvironment.unauthenticatedContext().firestore();
console.info('TEST_ENV is ready:n', testEnvironment);
console.info('GUEST_USER is ready:n', guestUserContext);
});
然后尝试运行一些简单的测试，像这样:
import { assertSucceeds } from '@firebase/rules-unit-testing';
import { guestUserContext } from '../integration-setup';
describe('Offers collection tests', () => {
it('should allow to read offers for any user', async () => {
const testQuery = guestUserContext.collection('offers');
expect(await assertSucceeds(testQuery.get()));
});
});
返回以下错误:
FAIL test/integration/firebase/firestore.rules.spec.ts (5.234 s)
Offers collection tests
✕ should allow to read offers for any user (5001 ms)
● Offers collection tests › should allow to read offers for any user
thrown: "Exceeded timeout of 5000 ms for a test.
Add a timeout value to this test to increase the timeout, if this is a long-running test. See https://jestjs.io/docs/api#testname-fn-timeout.
我已经检查了收集是否有任何问题，但如果我记录testQuery，它看起来很好。
我也按照上面错误的建议，将超时时间延长到30s (--testTimeout=30000)。什么产生了奇怪的结果。我的测试通过了，但还是出现了这样的错误:

在我看来，什么应该使这个测试失败。你有什么想法可能是错误的，我该如何解决这个问题?
我遇到了这个问题。我有几个与Firebase规则相关的Jest测试，所有这些测试都由于超时而失败，而我所有的Firebase数据库规则测试都通过了。
经过大量的研究，我了解到的是，至少在我这边，这个问题与使用jsdom的测试环境有关。当我切换到Jest的默认测试环境，即node时，测试又开始通过了。
我找到的主要帮助是这个线程(原文如此)React native repo。https://github.com/facebook/react-native/issues/36342
整篇文章中最重要的一段是:这里的根本问题是RN的Jest环境现在只将react-native作为导出条件(而不是节点)导出，这意味着导出节点目标的包现在可能会以不同的方式解析。在firebase的情况下，它默认返回到ESM。老实说，这应该被标记为对Jest设置的突破性更改-抱歉。">
我希望这能帮助到别人。
我运行了您的设置，并且能够通过测试。检查这里的版本号，看看它是否是任何问题的原因。输出也可以以有意义的方式不同:
import { initializeTestEnvironment } from '@firebase/rules-unit-testing';
export let testEnvironment;
export let guestUserContext;
beforeEach(async () => {
testEnvironment = await initializeTestEnvironment({
firestore: {
host: '127.0.0.1',
port: 8080,
},
projectId: 'warzywniax',
});
guestUserContext = testEnvironment.unauthenticatedContext().firestore();
console.info('TEST_ENV is ready:n', testEnvironment);
console.info('GUEST_USER is ready:n', guestUserContext);
});
import { initializeTestEnvironment, assertSucceeds } from '@firebase/rules-unit-testing';
import { guestUserContext } from './lib.js';
describe('Offers collection tests', () => {
it('should allow to read offers for any user', async () => {
const testQuery = guestUserContext.collection('offers');
await assertSucceeds(testQuery.get());
});
});
