Xamarin.UITest 2.2.4启动会话在第一次测试中失败 [英] Xamarin.UITest 2.2.4 start session failed on the first test
本文介绍了Xamarin.UITest 2.2.4启动会话在第一次测试中失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
由于我的macOS使我更新到XCode 9.3，因此必须将Xamarin.UITest从2.2.2升级到2.2.4.
Since my macOS made me update to XCode 9.3 I had to upgrade Xamarin.UITest from 2.2.2 to 2.2.4.
问题是，当我运行所有测试时，第一个测试每次都会失败，并附有错误.我认为这不是测试问题，因为所有测试都可以在具有XCode 9.2和Xamarin.UITest 2.2.2的macOS上正确运行.另外，如果我删除该测试，那么下一个将成为第一个测试的测试将失败，并出现相同的错误.
The problem is that when I run all my tests, every single time the first one fails with the error attached. I think is not a test issue because all tests run correctly on a macOS with XCode 9.2 and Xamarin.UITest 2.2.2. Also if I delete that test, then the next one that is going to be the first one fails with the same error.
有人可以帮助我吗?提前非常感谢您！
Can anyone help me, please? Thank you so much in advance!
