Install

gem install minitest-rails-capybara

This installs the following gems:

minitest
minitest-rails
minitest-capybara
capybara

Configure

Follow the instructions to configure minitest-rails. Then add minitest-rails-capybara to the :test group in Gemfile:

gem "minitest-rails"

group :test do
  gem "minitest-rails-capybara"
end

Add the following to your test_helper.rb file to the test directory.

require "minitest/rails/capybara"

Usage

Capybara is intended to be used for automating a browser to test your application’s features. This is different than the integration tests that Rails provides, so you must use the Capybara::Rails::TestCase for your feature tests.

To generate these feature tests, you can use the feature generator:

rails generate minitest:feature CanAccessHome

You can now use Capybara in your feature tests!

require "test_helper"

feature "Can Access Home" do
  scenario "has content" do
    visit root_path
    page.must_have_content "Home#index"
  end
end

Or you can opt-out of the Capybara’s spec DSL by providing the --no-spec option:

rails generate minitest:feature CanAccessHome --no-spec

Which will generate a feature test using the Capybara spec DSL:

require "test_helper"

class CanAccessHomeTest < Capybara::Rails::TestCase
  def test_homepage_has_content
    visit root_path
    assert page.has_content?("Home#index")
  end
end

An alternative way to specify using Capybara is to provide :capybara as a second argument to describe:

require "test_helper"

describe "Can Access Home", :capybara do
  it "has content" do
    visit root_path
    page.must_have_content "Home#index"
  end
end

While not recommended, you can add Capybara to your integration tests. To do this add the following to your test_helper.rb file:

class ActionDispatch::IntegrationTest
  include Capybara::DSL
  include Capybara::Assertions
end

Specifying drivers

Tests can specify drivers by setting the metadata.

feature "Can Access Home" do
  scenario "has content", js: true do
    visit root_path # Visited with JavaScript driver
    page.must_have_content "Home#index"
  end
end

Running Tests

To run your tests use the rails test that ship with rails.
