CircleCI - error while loading shared libraries

[udos]

when I try to run cypress tests in CircleCI via npm run cy:run, the following error is thrown:

npm run cy:run

> trail-scout@1.0.0 cy:run /home/circleci/project
> cypress run

It looks like this is your first time using Cypress: 3.1.3

[12:33:54]  Verifying Cypress can run /home/circleci/.cache/Cypress/3.1.3/Cypress [started]
[12:33:54]  Verifying Cypress can run /home/circleci/.cache/Cypress/3.1.3/Cypress [failed]
Cypress failed to start.

This is usually caused by a missing library or dependency.

The error below should indicate which dependency is missing.

If you are using Docker, we provide containers with all required dependencies installed.

/home/circleci/.cache/Cypress/3.1.3/Cypress/Cypress: error while loading shared libraries: libXtst.so.6: cannot open shared object file: No such file or directory
----------

Platform: linux (Debian - 9.5)
Cypress Version: 3.1.3

as a workaround I install the missing dependencies manually (before I run cypress tests):

sudo apt-get update
sudo apt-get install libxtst6 libgconf-2-4 libnss3 libasound2

Cypress provide docker images for circle with all deps

@YOU54F, I tried that before. same error.

[bahmutov]

@udos please provide your full circleci file. We run literally hundreds of projects on Circle, and we recommend using Cypress docker images https://github.com/cypress-io/cypress-docker-images as a base, because they have all OS dependencies installed already.

The simplest way to run Cypress on Circle is via Cypress orb, see here: https://github.com/cypress-io/circleci-orb

@bahmutov, I tried orbs after I got "inspired" :) by your presentation https://www.youtube.com/watch?v=J-xbNtKgXfY (but I got stuck and switched to the old school way of doing it).

my .circleci/config.yml to get cypress doing something on circleci is this

@udos so it seems to me Cypress tests run in image circleci/python:3.6.6-stretch-node right? which does not have Cypress OS dependencies ...

[udos]

@bahmutov yes. I need python to start django server to run cypress tests.

[bahmutov]

@udos I am afraid there is no getting around it then - you need the Cypress OS dependencies http://on.cypress.io/continuous-integration#Dependencies in the image that actually runs Cypress tests. Maybe there is a way in Circle to run your server in one image (the image with Python), and run Cypress tests in another image (cypress/base:8 in your case), but I don't know how one would configure this

[udos]

@bahmutov, no worries. I was about to propose you what you wrote ;) note: maybe as a CircleCI partner they could add this dependendencies to images they provide (to make cypress integration easier).

last (related) question: in this case orbs don't help either. they simplify things only for node.js based projects. correct?

[bahmutov]

Yes, we will propose adding these dependencies to Circle full images

And yes, orbs are not going to help with cases when you need different environments in Circle, or at least I don't know if they can help here

[udos]

thanks. no worries. cypress is a great tool!

@bahmutov it seems Cypress prepared images for python/ruby/XXX + headless browser based testing. I am able to run cypress based e2e tests with circleci/{lang}:{version}-node-browsers type of an image.

Example: circleci/python:3.8-node-browsers

[bahmutov]

Excellent but these are circleci prepared images not by cypress

Hello folks, sorry for hijacking this ticket, but is there any documentation available in 2020, about which docker image should I import (I'm not using orbs because of internal reasons) in order to run tests?

Use-case: git clone repo, npm install, then cypress run. I have tried various combinations and installing some ubuntu video dependencies, but there all stuck to

Cypress failed to start.

This is usually caused by a missing library or dependency.

The error below should indicate which dependency is missing.

Any help will be really appreciated!

[gimpiron]

hey @tillias have you try this one? https://docs.cypress.io/guides/guides/continuous-integration.html#Docker

[bahmutov]

@tillias you can always inspect our base Docker images to see what Linux libraries we install to have Cypress working https://github.com/cypress-io/cypress-docker-images/tree/master/base

[tillias]

Hello folks, many thanks for the response,

I'm using cypress/browsers:node12.14.1-chrome83-ff77 since November 2020, not sure if it latest, but it simply works:

https://github.com/tillias/microservice-catalog/blob/master/.circleci/config.yml

[bahmutov]

You can find the list of Docker images with pre-installed browsers in our repo https://github.com/cypress-io/cypress-docker-images/tree/master/browsers#cypressbrowsers
