Interesting, how can we recreate this failure? Is there a small example public repository that shows this behavior?

wichopy · 2017-11-17T18:48:01Z

My tests started running randomly but then this issue came up again. After looking into it more, I noticed the tests started working after changing the way I was defining env vars in my Jenkinsile. I made dynamic env vars with bash scripts grabbing the current branch name and date for naming reports that I am autogenerating.

When ran a simple cypress run with no extra arguments, my tests started running again.

With Jenkin's crazy idiosynchrasies I think I will find another way to get this information or just have simpler report titles... this caused too many headaches for me.

joelgrimberg · 2018-01-18T08:21:10Z

Just found out that I have the same problem. I will try to reproduce it in a public repo.

possibly related:
meetalva/alva#137

has somebody found a workaround?

wichopy · 2018-01-18T12:52:52Z

Funny enough I got this error again yesterday evening when we reset our build server. This time I notice this in the logs before the ‘BrowserWindow’ error came up.

_RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL

wichopy · 2018-01-18T12:59:34Z

I found this: https://issues.jenkins-ci.org/browse/JENKINS-23736

Last time I debugged this issue, I physically logged in on the machine and ran the cypress tests myself during debugging, and never logged off. I think this may be our answer, going to try it out when I get into work.

wichopy · 2018-01-23T17:08:42Z

No luck with having the account logged in. I was able to run cypress manually but the automated cypress command doesn't work.

wichopy · 2018-01-24T20:28:16Z

Seems like this error is specific to MacOS, ran on our Jenkins server running on Ubuntu and everything is working fine. Possible fix could be using Cypress's docker image?

Can you attempt to follow these directions? May be related to Jenkins permissions issues https://stackoverflow.com/a/21028195/5878476

Probably not related to permission, I did whatever this thread suggesting me but got no lucky.

I'm attempting to run some cypress tests on SemaphoreCI within their OSX environment and am encountering this issue as well.

OSX : 10.14.5

When running "cypress run", the following error shows:

After searching around, I haven't found a way to get this to work. So I resorted to installing Chrome, ie brew install caskroom/cask/google-chrome. This installed Chrome 75 as of this writing.

After installing Chrome into /Applications, I then run cypress run -b chrome, which it was able to run the test with the full log output here:

Warning: Cypress can only record videos when using the built in 'electron' browser.

You have set the browser to: 'chrome'

A video will not be recorded when using this browser.

So it appears that one is actually able to run the test, but it's just not able to run the test using electron chromium browser, but it's able to run it using the external Chrome app.

This now appears to be more of a Cypress issue more so than SemaphoreCI's OSX. It also appears that the errors are different between running under electron vs chrome.

bahmutov · 2019-07-12T14:08:51Z

Could be old Electron version issue, I wonder if Electron upgrade in #4355 or #4354 fixes this.

I will add Mac build to the Semaphore v2 CI project in https://github.com/cypress-io/cypress-example-kitchensink to see if we can recreate the problem - and to confirm that Electron upgrade fixes it when it is released

bahmutov · 2019-07-12T14:40:46Z

I have set up Mac CI build cypress-io/cypress-example-kitchensink#269, it is showing the problem, let's recheck after upgrading Electron version

jennifer-shehane · 2021-02-03T08:39:34Z

Since this issue hasn't had activity in a while, we'll close the issue until we can confirm this is still happening. Please comment if there is new information to provide concerning the original issue and we'd be happy to reopen.

And now strangely, after not working several times in a row, I just ran again and it worked.

Two possibilities come to mind:

It's totally random whether it fails or passes, as it's due to some race condition or intermittent issue.
One thing I did before running again this time is I open a Screen Sharing session to the Mac server and logged in (I was already logged in with SSH, so clearly that is not sufficient). I was logged out, I think because the server was rebooted recently. I wonder if for some reason the electron browser is dependent on some user being logged in to the GUI (not just SSH)?
