How do you change the testing default driver for a Cucumber test in Capybara?

Question

In the documentation provided by Capybara, you can change the default_driver on a specific test group:

describe 'some stuff which requires js', :js => true do
  it 'will use the default js driver'
  it 'will switch to one specific driver', :driver => :selenium
end

What if I wanted to do this for a specific cucumber test group? How would I add those parameters?

When /^I do something$/  do
  fill_in "a_text_box", :with => "stuff"
  fill_in "another_text_box", :with => "another_thing"
end

Thanks!

Answer 1

In cucumber, I've done this in two steps:

In /features/support/env.rb, place the following line:

Capybara.javascript_driver = :webkit

Then in the cucumber feature, just before the specific scenario, add @javascript just before the scenario -- like this:

@javascript
Scenario: Successful sign in - with no flash message if using current firefox
When I'm using a current version of Firefox
When I visit the practitioner home page with "[email protected]"'s token
Then I should be signed in as practitioner "Jane Doe"
And I should be on the practitioner activities welcome page
And I should not see a flash message warning me I have an unsupported browser

This tells cucumber to use the javascript driver when it runs that particular scenario.

This is how I've done this using Capybara Webkit -- I'm sure other drivers are similar.

Capybara.current_driver = :webkit # temporarily select different driver
#... tests ...
Capybara.use_default_driver       # switch back to default driver
