2. How to Dockerize WDIO

How to dockerize automation framework

Prerequisite: Docker installed on your laptop

1. Create Dockerfile - or simply use this one:

Note: you need to create Dockerfile with no extension(no .js no .anything) in the framework directory

FROM node:12
# Set up working directory
WORKDIR /app
# Install chrome and other dependencies
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list
RUN apt-get update -qq && apt-get install -y -qq --no-install-recommends \
   vim \
   python3-setuptools \
   python3-pip \
   google-chrome-stable \
   libnss3-dev \
   xvfb \
   openjdk-8-jdk \
   gcc libpq-dev \
   python3-dev python3-pip python3-venv python3-wheel \
 && apt-get clean \
 && rm -rf /var/lib/apt/lists/*
RUN pip3 install wheel

COPY . .
RUN mkdir ~/Downloads
RUN npm i
RUN npm rebuild node-sass

# Run all tests
CMD npm test

2. Create new docker image by running this command in a terminal:

 docker build .

3. Find id of your new docker image by running:

 docker images

4. Run your test inside docker container by specifying first 3 characters of your docker image id(b92 is an example):

 docker run -it b92

Bingo!

Now you know how to dockerize your test app.
