A very short manual named How to run OpenStack Horizon integration tests or How to run Selenuim tests without GUI

Didn’t google “how to run horizon integration tests” unswer in 10 seconds. Making note how to do it.

My development environment usually looks like: macbook + VM with Ubuntu Server or CentOS without GUI. I try to run all tests inside VMs. In case of Selenium tests, I need some preparation for it:

  1. $ sudo apt-get install firefox
    this command will install FireFox. Selenium has WebDriver for it out of the box
  2. $ sudo apt-get install xvfb
    install Virtual Frame Buffer for X Server (https://en.wikipedia.org/wiki/Xvfb)
  3. Run tests:
    • Simple way for OpenStack Horizon:
      ./run_tests.sh –integration –selenium-headless
    • Hard way for any project:
      • Start xvfb:
        $ sudo Xvfb :10 -ac
      • Start headless FireFox:
        DISPLAY=:10 firefox
      • run tests
