Running tests on the server

Since front end tests require a web browser, it's difficult to run tests within usual browser on servers that usually have not graphics installed. Fortunately there is a headless (without user interface) Google Chrome named puppeteer that could be used for running in-browser tests on the server side.

There is a pre-built docker image alekzonder/puppeteer and it could be easily used for unit tests, but it does not contain java so it cannot run e2e tests. We need to build custom docker image based on alekzonder/puppeteer with java support. Also we will upgrade puppeteer version to Chrome 75, install some dependencies globally to avoid installation each time test running. Note that we are using node:8 base image instead of node:8-slim as it's used in alekzonder/puppeteer. It's because java installation fails with node:8-slim. Additionally we will remove unnecessary tools.

Create a folder with file named Dockerfile:

Build the docker image (it could take several minutes):

docker build -t node-protractor .
