我正在使用 selenium webdriver ， appium ＆ ios webkit debug proxy处理iPhone自动化 .

Configurations:
OS X Version 10.11.2
Appium 1.3.5
Xcode: 7.2
Device: iPhone 6[9.2]

我使用Xcode在iPhone中安装了safariLauncher应用程序 .

脚步：

  • 我通过终端启动了appium .

  • Cmd: Appium &

  • 然后启动了ios-webkit-debug-proxy .

  • Cmd: ./bin/ios-webkit-debug-proxy-launcher.js -c [device udid]:27753 -d

我每次启动任何测试用例执行之前都会启动appium和webkit服务器 . 只有第一个测试用例工作正常，第二个测试用例继续在appium日志中遇到以下错误：

code error: Failed to start an Appium session, err was: Error: Instruments crashed on startup
info: [debug] Error: Instruments crashed on startup
    at Instruments.onInstrumentsExit (/usr/local/lib/node_modules/appium/node_modules/appium-instruments/lib/instruments.js:389:31)
    at null.<anonymous> (/usr/local/lib/node_modules/appium/node_modules/appium-instruments/lib/instruments.js:308:12)

info: <-- POST /wd/hub/session 500 153251.340 ms - 182

请建议任何解决方案 .
