[🐛 Bug]: Selenium 4.15 with C# - Exception in Parallel Test Execution "OpenQA.Selenium.NoSuchDriverException : Unable to obtain chrome using Selenium Manager" #13342

dcdraper · 2023-12-20T22:39:04Z

What happened?

The failures are intermittent and do not happen in each run.

The tests fail with selenium-manager.exe exception "Unable to obtain chrome using Selenium Manager" and error message "The process cannot access the file because it is being used by another process. (os error 32)"

We are using a .runsettings file and setting NumberOfTestWorkers to 8. Only about three tests fail at the beginning of each run. It seems that once chrome is installed by one of the early tests/threads that the issue no longer presents.

Version 4.15 is the first and only version we have tried using to manage chrome and chromedriver.

As a workaround we are running the command "selenium-manager.exe --browser chrome --debug" on the test agent in the pipeline after building the solution and before the tests start running.

How can we reproduce the issue?

.runsettings file:
<?xml version="1.0" encoding="utf-8" ?> <RunSettings> <!-- Parameters used by tests at run time --> <TestRunParameters> <Parameter name="environment" value="DEV" /> <Parameter name="browser" value="CH_HEADLESS_MODE" /> <Parameter name="gridExecution" value="false" /> <Parameter name="includeScreenshotsInReport" value="true" /> <Parameter name="generateFileWithFailedTests" value="true" /> <Parameter name="loglevel" value="INFO" /> </TestRunParameters> <NUnit> <NumberOfTestWorkers>8</NumberOfTestWorkers> </NUnit> </RunSettings>

4.16.0 is out since a couple of weeks.

Can you please check that version?

dcdraper · 2023-12-27T19:56:21Z

@diemol I cannot use 4.16.x due to issue #13261 which is not fixed until version 4.17. Do you know when to expect that version to be available?

titusfortner · 2023-12-28T04:22:29Z

We're trying to release when Google releases chrome, so we're shooting for - https://chromiumdash.appspot.com/schedule

You can try to use nightly, the last built should work... Hmm, looks like I messed up the nightly build with one of the recent changes, though, I guess I need to figure that out.

titusfortner · 2023-12-28T16:52:30Z

And I just noticed this is C# not Java, so no nightly. Also, I think this may be related to #12425 ?

tripplite · 2024-01-04T18:23:31Z

You aren't alone. We started experiencing similar, if not the same issue as of stable version 4.16.1. We tried 4.16.2 as well and the issue is not resolved. We rolled back to 4.15.0 and all is well. Essentially, we have a .NET project (C#) which runs tests via Azure DevOps CI/CD in parallel across multiple agents. Have been using Selenium for some time and this is seemingly our first trouble.

4.15.0 - Example of log output from initial SmokeTest run via DevOps agent:

We might try and see if the workaround mentioned "selenium-manager.exe --browser chrome --debug" will work for us but we will likely stay on 4.15.0 for the time being.

tripplite · 2024-01-26T13:38:43Z

Heads up - we have upgraded and tested 4.17.0 version and thus far, it appears to be working.

titusfortner · 2024-01-26T13:42:05Z

Excellent. I'll close this, then. We can re-open if we determine this bug is still present

dcdraper · 2024-01-26T18:54:05Z

@titusfortner
We are still seeing the errors with Selenium 4.17. We run 8 in parallel but on one agent, not across agents like @tripplite.
The workaround to run "selenium-manager.exe --debug --browser chrome" before the tests start still seems to work for us.
