Testing a simple web application using Docker and Galen

This is a Docker tutorial for creating a docker image for the Galen framework, above is the vid and below you will find some of the steps followed.

Steps

Pre-reqs
- Have node.js installed (For using galen without docker)
- Have Java installed (For using galen without docker)
- And docker installed
Create tests using galen
Create docker container for the galen-cli container
Build, Run and experiment with your new containers

Create a Dockerfile for the galen-cli container

Include clean ubuntu container
- FROM ubuntu
Create default/working directory
- WORKDIR /workdir

Install Java

RUN apt-get update && \
    apt-get install -y curl && \
    apt-get install -y software-properties-common && \
    add-apt-repository ppa:openjdk-r/ppa && \
    apt-get update && \
    apt-get install -y openjdk-8-jdk && \
    rm -rf /var/lib/apt/lists/* && \
    rm -rf /var/cache/oracle-jdk8-installer

Install Node.js

RUN curl -sL https://deb.nodesource.com/setup_8.x | bash - && \
    apt-get install -y nodejs

Install Galen framework
- RUN npm install -g galenframework-cli --unsafe-perm=true
Declare the entrypoint
- ENTRYPOINT ["galen"]
Add default parameters to be passed to the galen framework
- CMD ["--help"]

Build & Run

Install Galen locally
- npm install -g galenframework-cli
Run Galen locally
- galen test tests/ --htmlreport reports
Build the container
- docker build -t galenframework .
Run the container
- docker run -it galenframework
Run the container against Browser Stack
- docker run -v $(pwd):/workdir -it galenframework test tests/ --htmlreport reports -Dgalen.browserFactory.selenium.runInGrid=true -Dgalen.browserFactory.selenium.grid.url=http://USERNAME:ACCESSKEY@hub.browserstack.com/wd/hub
Run the container against Sauce Labs
- docker run -v $(pwd):/workdir -it galenframework test tests/ --htmlreport reports -Dgalen.browserFactory.selenium.runInGrid=true -Dgalen.browserFactory.selenium.grid.url=http://USERNAME:ACCESSKEY@ondemand.saucelabs.com/wd/hub
