ruby on rails - Visit method not found in my rspec

Question

My java web application is running on tomcat at http://localhost:8080/

Writing my first spec, home_spec:

require 'spec_helper'


describe "home" do

    it "should render the home page" do
       visit "/"

       page.should have_content("hello world")
    end

end

And running:

rspec

I get:

F

Failures:

  1) home should render the home page
     Failure/Error: visit "/"
     NoMethodError:
       undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1:0x242870b7>
     # ./spec/home/home_spec.rb:7:in `(root)'

Finished in 0.012 seconds
1 example, 1 failure

Failed examples:

rspec ./spec/home/home_spec.rb:6 # home should render the home page

Shouldn't this work because I have included capybara in the spec_helper?

How will it know to visit the correct url? what if my url is localhost:3030 or localhost:8080?

My gemfile:

source 'http://rubygems.org'

gem "activerecord"
gem "rspec"
gem "capybara"
gem "activerecord-jdbcmysql-adapter"

My spec_helper:

require 'capybara/rspec'

Regarding to rspec issues (https://github.com/rspec/rspec-rails/issues/360)

you should put

config.include Capybara::DSL

in spec_helper.rb, inside the config block.
