排毒测试命令失败，出现网络请求错误 #2665

问题描述

我正在使用具有以下配置的排毒：

"react": "16.13.1","react-native": "0.63.4" "detox": "^18.6.2","jest": "^26.6.3","jest-circus": "^26.6.3"

detox build 命令运行完美，但 detox 测试失败并出现以下错误：

detox[13327] INFO:  [DetoxServer.js] server listening on localhost:59074...
detox[13327] INFO:  Example is assigned to emulator-17544 (Pixel_API_28_AOSP)

    DetoxRuntimeError: Failed to run application on the device

    HINT: Most likely,your tests have timed out and called detox.cleanup() while it was waiting for "ready" message (over WebSocket) from the instrumentation process.

detox[13326] ERROR: [cli.js] Error: Command Failed: jest --config e2e/config.json --testNamePattern '^((?!:ios:).)*$' --maxWorkers 1 e2e

我认为 device.launchApp() 存在一些问题，因为应用程序也没有启动！

我的第一个Test.e2e.js文件：

describe('Example',() => {
  beforeAll(async () => {
    await device.launchApp();
  });

  beforeEach(async () => {
    await device.reloadReactNative();
  });

  it('should have welcome screen',async () => {
    await expect(element(by.id('EditTextId'))).toBeVisible();
  });
});
