Short Description
Protractor headless test execution environment
Full Description

Dockerfile for Protractor test execution
This image contains a fully configured environment for running Protractor tests
under Chromium and Firefox browsers.

Installed software
Xvfb The headless X server, for running browsers inside Docker
node.js The runtime platform for running JavaScript on the server side, including Protractor tests
npm Node.js package manager used to install Protractor and any specific node.js modules the tests may need
Selenium webdriver Browser instrumentation agent used by Protractor to execute the tests
Java 8 SE Needed by Selenium
Chromium The OSS core part of Google Chrome browser
Firefox Firefox browser
Protractor An end-to-end test framework for web applications
Supervisor Process controll system used to manage Xvfb and Selenium background processes needed by Protractor
In order to run tests from a CI system, execute the following:

docker run --rm -v <test project location>:/project caltha/protractor
The container will terminate automatically after the tests are completed. The output of supervisord visible on the console is not interesting in most circumstances. You should check target/supervsor.out file to see the output of Protractor. Dispalying the file in an Unix terminal using cat is recommended over opening it using an editor because the file contains ANSI escape sequences.

If you want to run the tests interactively you can launch the container and enter into it:

CONTAINER=$(docker run -d -v <test project location>:/project --env MANUAL=yes caltha/protractor)
docker exec -ti $CONTAINER sudo -i -u node bash
When inside the container you can run the tests at the console by simply invoking protractor. When things don't work as expected, you should check Selenium WebDrover output in /var/log/supervisor/webdriver-err.log. When you are done, you terminate the Protractor container with docker kill $CONTAINER

CI systems integration
An example project included in the source repository show how jasmine-reporters module can be used to generate JUnit-style test reports that can be used by Jenkins and other tools to display test results or fail the build if test failures are detected.
