HI 求助啊,我目前遇到一个问题A new session could not be created. 无法联调测试,当我关闭或者打开模拟器都会出现这个错误,单独执行脚本就会报错。
adb 执行确实可以看到的手机

List of devices attached
192.168.56.101:5555 device

appium也监测到了我手机,但是为什么联调不成功呢,求大神解救啊。

以下是过程log,写了一个网上看到很简单的python测试计算器的脚本,但是出现了一个这么问题,查了好几天没有很好的解决办法。大家有人知道么?

log里面有这么一句:Requested a new session but one was in progress。 说明appium server正在处理上一个session。

2个方案:

  1. 这个问题说明你的appium server还在运行,此事你可以关掉你的appium,然后重新打开。
  2. 你可以在启动appium server的时候,指定override old session,这样就不会出现这个问题了。

#1楼 @hp_test 您好 我试了一下 还是不行?请问有还有其他方法么?与其他软件冲突么、

请先正确使用 markdown 。。。

另外,我相信你试了 @hp_test 的方法后日志不会和帖子正文一样。你先确认下是不是确实试了之后错误日志还是和正文一样?

正如@hp_tests所说的,应该是有session没有关闭。把appium server关闭再打开,只运行一次测试脚本应该没问题吧?能不能把测试脚本贴上来,大家都看看是哪里不对。

把sever重启

重启手机

直接关闭server即可。这是因为session已经建立,第二个又要建立

你好,想请教下,怎么能保证每次执行完关闭session呢,每次感觉只是调试运行下,结果下次运行就不行了,然后报UiAutomation not connected!
