minitest-capybara

Capybara matchers support for minitest unit & spec

Why?

Capybara has good support for RSpec.

If you want to use it with minitest, you can of course write:

assert page.has_content?("Hello")

but:

it's kinda ugly
you don't have meaningfull error messages.

With this project minitest gets all the good stuff.

Rails integration

Check out minitest-rails-capybara

Usage

See example app: https://github.com/wojtekmach/minitest-capybara-example

Add to Gemfile:

# Gemfile
group :test do
  gem "minitest-capybara"
end

# features/my_feature.rb
require 'test_helper'

feature "My Super Feature" do
  given(:lion) { ... }

  background do
    visit "/feature"
  end

  scenario "this awesome feature" do
    page.must_have_content("Awesome Feature")
  end
end

Or if you prefer to create seperate test class for acceptance tests.

# test/test_helper.rb
require "capybara/rails"

# for just minitest/unit
class AcceptanceTest < Minitest::Test
  include Capybara::DSL
  include Capybara::Assertions

  def teardown
    Capybara.reset_session!
    Capybara.use_default_driver
  end
end

# for minitest/spec
class AcceptanceSpec < Minitest::Spec
  include Capybara::DSL
  include Capybara::Assertions

  def teardown
    Capybara.reset_session!
    Capybara.use_default_driver
  end
end

and you can use it like this:

# test/acceptance/home_test.rb
require "test_helper"

class HomeTest < AcceptanceSpec
  it "home test" do
    visit "/"

    assert_content "Homepage"
    page.must_have_content "Homepage"

    within ".login" do
      refute_content "Signed in as"
      page.wont_have_content "Signed in as"
    end

    assert_link "Sign in"
    assert_link find(".login"), "Sign in"
    find(".login").must_have_link("Sign in")

    assert_selector 'li:first', text: "Item 1"
    page.must_have_selector 'li:first', text: "Item 1"
  end
end

Capybara drivers

Switching drivers is easy with minitest-metadata:

require 'minitest-metadata'

class AcceptanceSpec
  before do
    if metadata[:js]
      Capybara.current_driver = Capybara.javascript_driver
    else
      Capybara.current_driver = Capybara.default_driver
    end
  end
end

class HomeTest < AcceptanceSpec
  it "home with ajax", js: true do
    visit "/"
    page.must_have_content "AJAX enabled..."
  end
end
