Integration tests

This code uses Watai framework for integration testing.

Install integration tests environment

To run the tests with Watai, we need the Java JRE and a Selenium standalone server.

Install Java JRE

Check if a Java Runtime Environment (JRE) is already installed on your environment with:

java -version
# Expected answer example: java version "1.8.0_40"

If you get an error, download Java last JRE version on the Oracle website.

Install Selenium

Download the standalone Selenium server on the official website.

Your download result is a Java .jar file (e.g., selenium-server-standalone-3.4.0.jar)

Move this file to the desired directory. In this example, we will save it to: /opt/local/lib/selenium

And register the jar full path in $SELENIUM environment variable:

export SELENIUM=/opt/local/lib/selenium/selenium-server-standalone-3.4.0.jar

To test your installation, run:

java -jar $SELENIUM
# Expected answer example:
# 15:26:11.981 INFO - Selenium build info: version: '3.4.0', revision: 'unknown'
# 15:26:11.982 INFO - Launching a standalone Selenium Server
# (...)
# 15:26:12.323 INFO - Selenium Server is up and running

Then, end it with Ctrl-C.

Select testing browser

To run the integration tests locally, you need a testing browser. Default configuration in this project uses Chrome browser.

If you have Chrome, install chromedriver as follows:

sudo npm install --global chromedriver

This will add a chromedriver to your global environment. Its installation directory (e.g., /usr/local/lib/node_modules/chromedriver) will be used in the next step.

If you don't have Chrome, update the browser name in tests/integration/config.js. E.g., for firefox:

    browser: 'firefox',

And this doesn't need further driver installation.

Link Chromedriver & Selenium

Go in the Selenium directory and add a (symbolic) link to the chrome driver:

cd `dirname $SELENIUM`
sudo ln -s /usr/local/lib/node_modules/chromedriver/lib/chromedriver/chromedriver chromedriver

Run tests

Every step is runned in a new terminal window.

  1. Terminal window #1: in fr.openfisca.org directory, run the web site in developement mode
npm run dev
# Expected answer example:
# DONE  Compiled successfully in 2276ms                                3:25:21 PM
# > Ready on http://localhost:3000
  1. Terminal window #2: run the selenium server
java -jar $SELENIUM
# Expected answer example:
# 15:26:11.981 INFO - Selenium build info: version: '3.4.0', revision: 'unknown'
# 15:26:11.982 INFO - Launching a standalone Selenium Server
# (...)
# 15:26:12.323 INFO - Selenium Server is up and running
  1. Terminal window #3: in fr.openfisca.org directory, run the integration tests (this step opens Chrome browser)
npm run test:integration
# Expected answer example:
# (...)
# ⨁  fr.openfisca.org
# ✔  L'en-tête doit présenter ce que fait OpenFisca.
# ✔  La page d'accueil doit indiquer les informations de documentation.

Tracking

fr.openfisca.org uses Matomo (formerly Piwik) to track visits. The tracking is configured in piwik.config.json. Change the information there if you are running a seperate Piwik or Matomo instance.
