我正在使用 WebDriverIO 和 Appium 运行测试套件来自动化 Android 应用程序测试。我的测试套件在第一次执行时成功运行，但在第二次执行时，我收到“Appium 在超时前退出”错误。第三次执行运行良好，但第四次执行再次出现同样的错误。
这是我对 package.json 的开发依赖
"devDependencies": {
"@wdio/appium-service": "^8.8.8",
"@wdio/cli": "^8.8.8",
"@wdio/local-runner": "^8.8.8",
"@wdio/mocha-framework": "^8.8.7",
"@wdio/spec-reporter": "^8.8.7",
"appium": "^2.0.0-beta.66",
"appium-uiautomator2-driver": "^2.23.0"
},
这是我从 wdio.const.js 获得的功能：
capabilities: [
{
platformName: 'Android',
'appium:platformVersion': '13.0',
'appium:deviceName': 'Pixel_3a_API_33_x86_64',
'appium:automationName': 'UIAutomator2',
'appium:app': `${join(
process.cwd(),
'./app/android/ApiDemos-debug.apk'
)}`,
},
],
这里是完整的错误：

我不确定为什么每次运行测试套件时都会出现此错误。可能是什么原因导致此问题？我该如何解决？
我删除并重新安装了node_modules和package-lock.json文件。但这没有用。我还想指出，当我使用本地安装的 appium 包时，我遇到了同样的错误。
你找出问题所在了吗？
