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

Question

While running smoke tests in CodeFresh we occasionally get this error

[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.)

[xUnit.net 00:02:41.43]            at Live_Automation.Features.SmokeTestsOnLiveFeature.ScenarioStart()

This happens on average 1 test run in 10 and often it is just one scenario as below

Test Run Failed.
Total tests: 52
     Passed: 51
     Failed: 1

The failing test is random as is the time of day this may happen. The test suite is built around Visual Studio/C#/Selenium/Xunit

On an either rarer occasion we get this

[xUnit.net 00:03:26.88]       OpenQA.Selenium.WebDriverException : unknown error: session deleted because of page crash
[xUnit.net 00:03:26.88]       from unknown error: cannot determine loading status

Now when this happens all scenarios from this point will fail Has anyone got any ideas please about what is causing this. I do not think it is the tests.

Thanks in advance

Answer 1

it means somewhere you are using send_keys(filepath) and the file doesn't exists in that path

see if you are using this some where

Answer 2

I have resolved this issue. Since adding this line there have been no problems.

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