Cypress test runner hangs immediately on running cypress open

[jenkshields]

Current behavior:

When running yarn run cypress open, the Cypress Test Runner opens but immediately hangs. There is no output in the terminal, unless I force quit Cypress, when it logs The Test Runner unexpectedly exited via a exit event with signal SIGKILL (which is to be expected).

Manually opening the globally installed app works fine.

Note! I ran into #6377 when installing, and worked around by installing rjxs and rxjs-compat - unsure if that could be related.

Desired behavior:

Cypress Test Runner should open normally.

Test code to reproduce

No tests are written - I've tried this both in a project without a cypress folder, and in one which has the folder filled with test examples with the same result.

Versions

Cypress 4.0.1
Mac OS Catalina 10.15.3 Beta (19D62e)
Firefox Nightly 74.0a1
yarn v2

Hi, same happened to me. For me the problem arouse when I changed my build routine from 'npm run build' to 'yarn build'. I kinda think the problem is the location of the build output, it changed, or the cypress files cannot be found etc. It does not work with 'npx cypress open' either.

F**k these package managers man, I sometimes feel I spend more time figuring out what went wrong again with my packages than with coding... So much of making your life easier.

UPDATE: I had no trouble at install, and there is no log message at force quitting for me.

I would like to update this issue with some details.

Cypress package version: 4.0.2
Cypress binary version: 4.0.2
OS: GNU/Linux 5.3.0-28-generic x86_64

Firstly, Cypress hangs only on yarn cypress open or yarn cypress version
After a couple of minutes, the Cypress window (when running yarn cypress open) is starting but it doesn't have any content, just grey background.
I've tried to run cypress with the command
$ DEBUG=cypress:* yarn cypress open

Full debug output is here https://pastebin.com/BD98wtPE
Here's some errors that are shown even when the debug variable is unset.

Also, when I try to click electron menus I get something like this (links do work, however)

Running into the same issue with yarn v2. Highly suspect it's yarn v2 Plug'n'Play related.

It looks like more details and some workaround (which didn't work for me, though) were provided in another issue
#6377

[maxime1992]

This is happening to me as well and I'm completely stuck ⚠️.
Cypress doesn't work locally at all, no matter how hard I try.

I'm not using yarn 2 so probably not coming from there:

yarn --version
1.21.1

Here's what I tried so far:

Cypress 3.6.0

• rm -rf node_modules && yarn ➡️ 🔴
• yarn run cypress cache clear && rm -rf node_modules && yarn ➡️ 🔴

Cypress 4.4.0

• rm -rf node_modules && yarn ➡️ 🔴
• yarn run cypress cache clear && rm -rf node_modules && yarn ➡️ 🔴

No matter what, I'm always stuck on that screen:

After some time, the only error that showed up in the console was that:

$ cypress open --project ./apps/public-site-e2e
It looks like this is your first time using Cypress: 4.4.0

  ✔  Verified Cypress! /home/maxime/.cache/Cypress/4.4.0/Cypress

Opening Cypress...

I don't think that's relevant but sharing in case.

EDIT: I also tried to reboot the computer in case... Same issue

[DanielCambray]

Same issue here since yesterday. It was working fine until then. I don't know what to do...

[maxime1992]

@brian-mann sorry for the ping but it feels like quite a huge issue. We're unable to run cypress at all. I'm still blocked and unable to work on any tests. Something which is quite worrying too: I tried cypress on another Linux machine where it was working fine on few days ago and it's broken too 🤷. On the contrary, my colleagues running it on Mac don't have any issue.

[DanielCambray]

Indeed, still not working here. I've tried many things, change node version, npm, yarn. Still the same issue.

I have managed to find an alternative, it's not perfect, far less stable, but at least I can run some tests. You can try to launch Cypress with docker. It works on ubuntu :

docker run -it \
  -v $PWD:/e2e \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  -v /var/run/dbus/system_bus_socket:/var/run/dbus/system_bus_socket \
  -w /e2e \
  -e DISPLAY=unix${DISPLAY} \
  --network=host \
  --entrypoint cypress \
  cypress/included:4.4.0 open --project .

[maxime1992]

So painful :( But thanks for sharing the solution @DanielCambray

[curvaton]

Hi,

I went through the same problem today. I have Ubuntu 18.04. On my side it appears it came from Chromium. I uninstalled it and now everything is back to normal. I found this solution remembering that this morning I had a notification that Chromium had been updated.

[maxime1992]

Oh my... 😱 @curvaton thanks! I didn't have to reinstall chromium-browser but just remove it.

What's going on... No idea! I still have chromium after "removing" it and now cypress does work 🤷

To be clear I just ran

sudo apt remove --purge chromium-browser

[lujoamel4]

I tried all of these solutions. However, it didn't work until I have installed cypress@4.4.1.

[flotwig]

@maxime1992 it sounds like you're running into this bug: #7020 - try cypress@4.4.1

[jennifer-shehane]

Hey everyone, recently there was an issue where Cypress would hang during opening in Ubuntu due to their changing how Chromium is installed. This was a priority fix for us, which is why we released a patch fix ahead of schedule as 4.4.1. Please upgrade to this version.

These recent comments appear to be unrelated to the original issue that was opened - which involve cypress open not working in Yarn 2. Closing this issue with yarn 2 as duplicate of #6377
