排毒：等待网络请求完成超时答案

【问题标题】：Detox: Waiting for network requests to finish timeout排毒：等待网络请求完成超时

【问题描述】：

我正在尝试设置 detox 在我的应用程序上运行 e2e 测试（react native + expokit）。正如我在https://github.com/wix/Detox/issues/1627 中提到的，我的测试一直超时

Waiting for network requests to finish.: (
    "http://10.4.12.38:19001/symbolicate",
    "http://10.4.12.38:19001/symbolicate",
    "http://10.4.12.38:19001/symbolicate",
    "http://10.4.12.38:19001/symbolicate",
    "http://10.4.12.38:19001/onchange"
)

我已将这些网址添加到detoxURLBlacklistRegex，但它并不能解决问题。正如我在https://github.com/wix/Detox/issues/1627 中所说的，我认为禁用实时重新加载会使测试通过，但并非总是如此——有时会，有时会超时。这是我的init.js：

const detox = require('detox');
const adapter = require('detox/runners/jest/adapter');
const specReporter = require('detox/runners/jest/specReporter');

const config = require('../package.json').detox;

// Set the default timeout
jest.setTimeout(30000);
jasmine.getEnv().addReporter(adapter);

// This takes care of generating status logs on a per-spec basis. By default, jest only reports at file-level.
// This is strictly optional.
jasmine.getEnv().addReporter(specReporter);

beforeAll(async () => {
  await detox.init(config, {
    launchApp: false,
  });
  await device.launchApp({
    permissions: { notifications: 'YES' },
    launchArgs: {
      detoxPrintBusyIdleResources: 'YES',
      detoxURLBlacklistRegex:
        '.*://10.4.12.38.*',
    },
  });
});

beforeEach(async () => {
  await adapter.beforeEach();
});

afterAll(async () => {
  await adapter.afterAll();
  await detox.cleanup();
});

这是踪迹：

That might be the reason why the test "Example should show hello screen after tap" has timed out.

【问题讨论】：

你解决了吗？我也有同样的问题。

【解决方案1】：

您是否尝试过转义特殊字符？它在 detox docs 中说，我们可以通过提供 正则表达式 来跳过某些 URL，从而在首选端点上禁用 EarlGrey's network synchronization mechanism 机制。

例如，

  beforeAll(async () => {
    await device.setURLBlacklist([
      '.*10\.4\.12\.38.*'
    ]);
  });

至少对我来说是这样 - 如果可行，请告诉我。
