问题描述
在 CodeFresh 中运行冒烟测试时，我们偶尔会遇到此错误
[xUnit.net 00:02:41.43] OpenQA.Selenium.WebDriverException : unkNown error: Chrome Failed to start: exited abnormally.
[xUnit.net 00:02:41.43] (unkNown error: DevToolsActivePort file doesn't exist)
[xUnit.net 00:02:41.43] (The process started from chrome location /usr/bin/google-chrome is no longer running,so ChromeDriver is assuming that Chrome has crashed.)

这种情况平均每 10 次测试运行 1 次，通常只有一种情况，如下所示
Test Run Failed.
Total tests: 52
Passed: 51
Failed: 1
失败的测试是随机的，这可能发生在一天中的时间。 测试套件围绕 Visual Studio/C#/Selenium/Xunit 构建
在极少数情况下，我们会得到这个

现在发生这种情况时，所有场景都将失败 有没有人对导致这种情况的原因有任何想法。我不认为这是测试。
