OpenQA.Selenium.WebDriverException：未知错误：Chrome 无法启动：在 CodeFresh 上异常退出

Question

在 CodeFresh 中运行冒烟测试时，我们偶尔会收到此错误

[xUnit.net 00:02:41.43]       OpenQA.Selenium.WebDriverException : unknown error: Chrome failed to start: exited abnormally.

这在 10 次测试中平均发生 1 次，通常只是以下一种情况

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

在更罕见的情况下我们会得到这个

现在，当这种情况发生时，从这一点开始的所有场景都将失败 有没有人对造成这种情况的原因有任何想法。我不认为这是测试。

Answer 1

这意味着您在某处使用 send_keys(filepath) 并且该文件不存在于该路径中

看看你是否在某个地方使用这个

Answer 2

我已经解决了这个问题。自从添加了这一行之后就没有问题了。

options.AddArguments("--disable-dev-shm-usage");
