# Setup for headless browser tests with minitest and capybara-webkit.
You need to install selenium-webdriver and capybara-webkit as gem. Capybara-webkit requires two system libraries **qt** and **xvfb**. To install execute:
`apt-get install libqtwebkit-dev`<br>
`apt-get install xvfb`
as sudo. This works for Debian Wheezy.
# Install the gems:
`gem install selenium-webdriver`<br>
`gem install capybara-webkit`
To run the headless browser you have to execute:
`DISPLAY=localhost:1.0 xvfb-run ruby TEST.rb`<br>
or you integrate it to your test.
For the following example `export 'DISPLAY=localhost:1.0'` is already in ~/.bashrc.
# Example test:
`
require 'rubygems'
require 'minitest/autorun'
require 'capybara/dsl'
require 'capybara-webkit'
Capybara.default_driver = :selenium
Capybara.default_wait_time = 20
Capybara.javascript_driver = :webkit
Capybara.run_server = false
Capybara.app_host = 'https://services.in-silico.ch'
class LazarWebTest < MiniTest::Test
include Capybara::DSL
def test_00_start
`Xvfb :1 -screen 0 1024x768x16 2>/dev/null &`
sleep 2
end
def test_01_visit
visit('/')
puts page.source
end
def test_99_kill
`pidof Xvfb|xargs kill`
end
end
`
