ruby on rails - Capybara: undefined method 'visit'

Question

When running my specs with rspec & capybara, it can't find capybara's visit method. Is there another initialization step I need to do?

$bundle exec rspec spec
/home/brian/projects/expense_track/expense_track/spec/requests/homepage_spec.rb:6:in `block (2 levels) in <top (required)>': undefined method `visit' for #<Class:0xb6572b8> (NoMethodError)

Gemfile:

group :test, :development do
  gem "rspec-rails"
  gem "capybara"
end

top of my spec_helper.rb:

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)

require 'rspec/rails'
require 'capybara/rspec'
require 'rspec/autorun'

homepage_spec.rb:

require 'spec_helper'

describe "The home page" do

  context "home page exists" do
    visit "/"
    page.should have_content("elephants")
  end
end

Just ran into this issue myself.

So the reason for this is there has been a somewhat undocumented change in Capybara. Capybara now makes the assumption that anything using it needs to be in the spec/features folder and it will make the proper assumptions. Anything left in the spec/requests folder will no longer work. Though there are workarounds.

For a context block you can add the parameter :type => :feature and this will fix that issue or you can change the name of a describe method at the beginning of a spec to feature and this should change it as well.

They announced this change in their Google group: https://groups.google.com/forum/?fromgroups=#!topic/ruby-capybara/5KfxezI-U0Q

Notably, we changed the :type that Capybara assumes your specs run under in RSpec to :feature (previously it was :request). The latest release of spec/features. Alternatively you can use the Capybara Feature DSL (feature instead of describe), which should work without any additional tweaking. If you see errors like undefined method visit, then you're probably encountering this issue. If you're including modules into :request specs, you will probably need to change that to :feature.

This was further discussed in the github issue: https://github.com/jnicklas/capybara/issues/814
