ruby on rails - run selenium without opening a browser in cucumber -

i have question using selenium in cucumber.

here cucumber features:

@selenium @javascript   scenario: create forum     given have site named "hairclub" , logged in admin     when on "admin" page 

to run, use command:

cucumber features/forum.feature 

it works fine; opens browser (as can see @selenium @javascript tag). looks good.

i want run same cucumber script not open browser; imagine if scenario grows take while run browser. want both capability run browser open , without browser opening. there command can pass terminal overwrite @selenium @javascript?

you can't run selenium without browser, because selenium works controlling browser.

however, can run cucumber features without using selenium.

if scenario doesn't require javascript can use mechanize:

capybara.default_driver = :mechanize 

if need test javascript, thoughtbot have released helpful gem: https://github.com/thoughtbot/capybara-webkit
