sudo apt-get install xvfb. Then save folowing code in
headless file, make it executable and put it on
$PATH, I prefere to put it in
~/bin - reload console.
if [ $(pidof -x Xvfb| wc -w) -eq 0 ]; then
Xvfb -ac -screen scrn 1024x768x24 :5.0 > /dev/null 2>&1 &
Now just go to your project and run your test like
headless rspec spec/ or
headless bundle exec rake.
Idea is simple, any command prefixed with
headless is executed into another (5.0) virtual window, so capybara will open a real Firefox browser, but it will not be visible in main (0.0) window.
