Cypress: Couldn't get heroku CI working

[uooq]

Overview: I've created a very simple test spec that I wanted to get running in a CI-enabled Heroku pipeline. However, it seems to fail due to some xvfb configuration issues.

I tried different flavors of buildpacks and chrome and electron both.

When missing a dependency I would get an error message on the heroku dyno about the missing dependency (e.g. xvfb, etc). However, once all the dependencies were installed, I then got this message;

~ $ ./node_modules/.bin/cypress run
It looks like this is your first time using Cypress: 1.1.0

[04:28:22]  Verifying Cypress can run /app/node_modules/cypress/dist/Cypress [started]
[04:28:22]  Verifying Cypress can run /app/node_modules/cypress/dist/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 using Docker, we provide containers with all required dependencies installed.

Platform: linux (Ubuntu Linux - 14.04)
Cypress Version: 1.1.0

on the advice of @brian-mann via your Gitter chat, I tried this command:
./node_modules/cypress/dist/Cypress/Cypress

However that produced no console output whatsoever.

Here's the heroku configuration I wound up with (after trying various buildpacks):

stack: cedar-14 (per heroku xvfb doesn't work with the new stack)
buildpack: https://github.com/heroku/heroku-buildpack-apt
Then I configured the Aptfile with these dependencies

xvfb
libgtk2.0-0
libnotify-dev
libgconf-2-4
libnss3
libxss1
libasound2

(copied out of your instructions).

I'm giving up on getting this running on heroku, but if you're having trouble recreating the situation, I could probably get something set up for you pretty quickly (the code part is trivial-- basically a hello world test.)

Hmm, can Heroku run based on a Docker image? We have cypress/base with dependencies, and it is very weird that Cypress running by itself produces no error output at all.

Resurrecting this because I just ran into this issue.

Here's my failed output:

@bahumtov I think Heroku supports Docker, not sure how to set it up though.

I'm not wed to Heroku though, is there a CI that Cypress recommends?

[bahmutov]

We are extensively using Circle, cannot recommend it high enough.

Our Drone CI threw the same error.

Any updates here?

I have not tried yet but I feel like these Nightmare set up instructions might actually help: https://github.com/oscarmorrison/nightmare-heroku. I'll give it a go soon if I can find a little bit of time. The problem, it is still relying on Cedar-14 that is deprecated and going away in early 2019, and using deprecated or unsupported build packs so not a good long-term solution.

I ended up using Codeship Basic, happy to share the details of the setup if needed. In the meantime I contacted Heroku supports to get their feedback on this.

EDIT: thx to Heroku support I found this: https://github.com/chap/cypress-heroku-ci

[bahmutov]

We have example project tested on Heroku CI, here is the app.json file https://github.com/cypress-io/cypress-example-kitchensink/blob/master/basic/app.json (Cypress v3.1.2)

[arshdeeptinna]

Any plan of updating cypress to work with heroku-18 as cedar-14 will go away in april

[bahmutov]

@arshdeeptinna please open a new issue, since this seems unrelated to the original issue

[bahmutov]

@arshdeeptinna I have looked around in https://github.com/cypress-io/cypress-example-kitchensink/issues/213 and could not find any modern Heroku buildpack with heroku-18 XVFB install. I don't want to write one, and suggest using "real" CI instead - something that can use our cypress-docker-images Docker image to have all OS dependencies.
