Problem running inside docker container

[fredcido]

Hello all, I am trying to run the tests inside a docker container, following the steps, using the following configuration:

FROM node:14

RUN apt-get update -y && apt-get install -y xvfb
ENV DISPLAY=':99'
RUN Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
RUN npm test

However, the tests hang, with no error message at all, I can't even get a clue on what's going on:

npm test

> [email protected] test /app
> jest "--selectProjects" "e2e" "--verbose"

Running one project: e2e

Test Suites: 0 of 5 total
Tests:       0 total
Snapshots:   0 total
Time:        422 s

Any hint on what's going on? I can't see any log messages

With the same setup as above, i do get the error:

events.js:292
 throw er; // Unhandled 'error' event
 ^

}

maybe new version 0.1.12 solved it.

jest-electron does not throw error if some library is missing. I managed to solve this by installing the system libraries needed to run Electron headless and running "npm test" with "xvfb-run":

FROM node:14

COPY . /usr/src/app
WORKDIR /usr/src/app

ENV JEST_ELECTRON_STARTUP_ARGS='--no-sandbox'

RUN apt-get update && apt-get install -y  \
    libnss3  \
    libatk1.0-0  \
    libatk-bridge2.0-0  \
    libgbm1  \
    libgtk-3-0  \
    libasound2  \
    xvfb

RUN npm ci

CMD xvfb-run npm test
