Using Capybara with RSpec<\/strong><\/h1>\n

\"Using<\/a><\/p>\n

 <\/p>\n

Load RSpec 2.x support by adding the following line (typically to your spec_helper.rb file):<\/p>\n

require ‘capybara\/rspec’<\/p>\n

If you are using Rails, put your Capybara specs in spec\/features.<\/p>\n

If you are not using Rails, tag all the example groups in which you want to use Capybara with :type => :feature.<\/p>\n

You can now write your specs like so:<\/p>\n

describe “the signin process”, :type => :feature do<\/p>\n

before :each do<\/p>\n

User.make(:email => ‘user@example.com’, :password => ‘password’)<\/p>\n

end<\/p>\n

it “signs me in” do<\/p>\n

visit ‘\/sessions\/new’<\/p>\n

within(“#session”) do<\/p>\n

fill_in ‘Email’, :with => ‘user@example.com’<\/p>\n

fill_in ‘Password’, :with => ‘password’<\/p>\n

end<\/p>\n

click_button ‘Sign in’<\/p>\n

expect(page).to have_content ‘Success’<\/p>\n

end<\/p>\n

end<\/p>\n

Use :js => true to switch to the Capybara.javascript_driver (:selenium by default), or provide a :driver option to switch to one specific driver. For example:<\/p>\n

describe ‘some stuff which requires js’, :js => true do<\/p>\n

it ‘will use the default js driver’<\/p>\n

it ‘will switch to one specific driver’, :driver => :webkit<\/p>\n

end<\/p>\n

Capybara also comes with a built in DSL for creating descriptive acceptance tests:<\/p>\n

feature “Signing in” do<\/p>\n

background do<\/p>\n

User.make(:email => ‘user@example.com’, :password => ‘caplin’)<\/p>\n

end<\/p>\n

 <\/p>\n

scenario “Signing in with correct credentials” do<\/p>\n

visit ‘\/sessions\/new’<\/p>\n

within(“#session”) do<\/p>\n

fill_in ‘Email’, :with => ‘user@example.com’<\/p>\n

fill_in ‘Password’, :with => ‘caplin’<\/p>\n

end<\/p>\n

click_button ‘Sign in’<\/p>\n

expect(page).to have_content ‘Success’<\/p>\n

end<\/p>\n

 <\/p>\n

given(:other_user) { User.make(:email => ‘other@example.com’, :password => ‘rous’) }<\/p>\n

 <\/p>\n

scenario “Signing in as another user” do<\/p>\n

visit ‘\/sessions\/new’<\/p>\n

within(“#session”) do<\/p>\n

fill_in ‘Email’, :with => other_user.email<\/p>\n

fill_in ‘Password’, :with => other_user.password<\/p>\n

end<\/p>\n

click_button ‘Sign in’<\/p>\n

expect(page).to have_content ‘Invalid email or password’<\/p>\n

end<\/p>\n

end<\/p>\n

feature is in fact just an alias for describe …, :type => :feature, background is an alias for before, scenario for it, and given\/given! aliases for let\/let!, respectively.<\/p>\n

Finally, Capybara matchers are supported in view specs:<\/p>\n

 <\/p>\n

RSpec.describe “todos\/show.html.erb”, type: :view do<\/p>\n

it “displays the todo title” do<\/p>\n

assign :todo, Todo.new(title: “Buy milk”)<\/p>\n

 <\/p>\n

render<\/p>\n

 <\/p>\n

expect(rendered).to have_css(“header h1”, text: “Buy milk”)<\/p>\n

end<\/p>\n

end<\/p>\n

Using Capybara with RSpec<\/strong><\/h2>\n

Capybara naturally fits with RSpec and no special integration is needed.<\/p>\n

describe “Create place scenario” do<\/p>\n

context “Go to home page” do<\/p>\n

it “opens homepage” do<\/p>\n

visit(get_homepage)<\/p>\n

end<\/p>\n

end<\/p>\n

context “Click on create object link” do<\/p>\n

it “opens create new object form” do<\/p>\n

find(:homepage_navigation_create_object).click<\/p>\n

end<\/p>\n

end<\/p>\n

end<\/p>\n

Using the DSL to interact with page elements, has one caveat: With every new context, a new Capybara session will be instantiated which is probably not what we want.<\/p>\n

Capybara::Session.new :driver helps manage this issue. For example:<\/p>\n

session = Capybara::Session.new :selenium # instantiate new session object<\/p>\n

session.visit() # use it to call DSL methods<\/p>\n

The session represents a single user interaction with the application, which is precisely what we want.<\/p>\n

It is a good practice to define a method in spec_helper.rb which will return the session object and use this session object when calling all Capybara methods inside RSpec context (session.visit, session.find, etc.)<\/p>\n
