对 2 个测试文件运行“排毒测试”时出现“错误：无法连接”

问题描述

我已经在我的 React Native 项目上安装了 Detox，它似乎运行良好，直到我添加了第二个测试文件。显然，在运行第一个文件的测试后，它出于某些原因更改了侦听端口，因此无法连接到新设备。

这是我的文件和终端日志：

e2e/test.e2e.js（第一个测试文件）

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

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

  it('should show hello screen after tap',async () => {
    await expect(element(by.text('AVC Diag'))).toBeVisible();
  });
});

e2e/test2.e2e.js（第二个测试文件）

describe('E',() => {
    beforeAll(async () => {
      await device.launchApp();
    });
  
    beforeEach(async () => {
      await device.reloadReactNative();
    });
  
    it('qwe',async () => {
      await expect(element(by.text('AVC Diag'))).toBeVisible();
    });
  });

e2e/config.json

{
    "testEnvironment": "./environment","testRunner": "jest-circus/runner","testTimeout": 120000,"testRegex": "\\.e2e\\.js$","reporters": ["detox/runners/jest/streamlineReporter"],"verbose": true
}

谁能帮我解决这个问题？使用我最好的朋友谷歌没有找到任何线索...
