Feature specs

Feature specs are high-level tests meant to exercise slices of functionality through an application. They should drive the application only via its external interface, usually web pages.

Feature specs are marked by type: :feature or if you have set config.infer_spec_type_from_file_location! by placing them in spec/features.

Feature specs require the Capybara gem, version 2.13.0 or later. Refer to the capybara API documentation for more information on the methods and matchers that can be used in feature specs. Capybara is intended to simulate browser requests with HTTP. It will primarily send HTML content.

The feature and scenario DSL correspond to describe and it, respectively. These methods are simply aliases that allow feature specs to read more as customer and acceptance tests. When capybara is required it sets type: :feature automatically for you.

Specify creating a Widget by driving the application with capybara

Given a file named “spec/features/widgetmanagementspec.rb” with:

require "rails_helper"

RSpec.feature "Widget management", type: :feature do
  scenario "User creates a new widget" do
    visit "/widgets/new"

    click_button "Create Widget"

    expect(page).to have_text("Widget was successfully created.")
  end
end

When I run rspec spec/features/widget_management_spec.rb

Then the example should pass.
