Use with testcafe docker image

I am curious if there is any way to include this library when running testcafe from within docker?

I have attempted to create a new docker image based off testcafe/testcafe, but ran into permissions-related issues when attempting to install testcafe-react-selectors via npm from within my new Dockerfile.

Another approach I made that I really am not entirely keen on involved essentially copying the Dockerfile from the testcafe github and adding multiple steps to basically ADD the testcafe release tar.gz, install gulp, build testcafe, copy the required directories to /opt/testcafe within the image and then finally install testcafe-react-selectors seperately. Not fun.

It’s entirely possible I’m missing something amazingly simple, but I would appreciate any advice you could give about being able to completely contain both testcafe and this library within a single-entrypoint docker image.

Thanks!

EDIT - Just to give you an example of the truly horrible hoops I jumped through…

FROM alpine:edge

RUN apk --no-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing/ add \
  nodejs nodejs-npm chromium firefox xwininfo xvfb dbus eudev ttf-freefont fluxbox

I had to slightly edit @sobolevn solution to add the /usr/lib/node_modules to NODE_PATH. If not, I was running in the following error :

ERROR Cannot prepare tests due to an error.

Error: Cannot find module 'testcafe'
    at Object.<anonymous> (/opt/testcafe/node_modules/testcafe-react-selectors/lib/index.js:8:17)

My resulting Dockerfile is the following :

FROM testcafe/testcafe

USER root

ENV NODE_PATH=/opt:/usr/lib/node_modules:/opt/testcafe/node_modules

# Installing custom dependencies:
RUN cd /opt/testcafe && npm install \
  testcafe-react-selectors

@lgriotti The cd command should change the current directory to the directory containing your package.json.
