I'm not a web developer so I never used Capybara integrated with the Ruby web app -- I always ran the tests as a separetly hosted application. However I'm currently making a Sinatra app and I suppose integrating it with the minitest would allow me to start and stop the app automatically that would be nice. But I can't figure out how to do that. I tried to follow https://sinatrarb.com/testing.html

# Gemfile
source "https://rubygems.org"
gem "sinatra"
gem "minitest"
gem "cuprite"

# main.rb
require "sinatra/base"
class MyApp < Sinatra::Base
  set :bind, "0.0.0.0"
  set :port, 8001
  get "/" do
    "hello"
  end
  run! if $0 == __FILE__
end

# minitest_cuprite.helper.rb 
require "capybara/cuprite"
Capybara.current_driver = Capybara.javascript_driver = :cuprite
Capybara.register_driver :cuprite do |app|
  Capybara::Cuprite::Driver.new app, "headless": false
end
require "capybara/minitest"
require "minitest/spec"
Minitest::Spec.include Capybara::DSL
Minitest::Spec.include Capybara::Minitest::Assertions
require "minitest/autorun"

# cat test.rb
require_relative "minitest_cuprite.helper"

ENV['APP_ENV'] = 'test'
require './main'
Capybara.server = :webrick
Capybara.app = MyApp.new

describe :test do
  before do
    Capybara.reset_sessions!
  end
  it do
    visit "http://localhost:8001"
    require "irb"
    binding.irb
  end
end

but when the browser window opens the localhost is down, it does not look like Sinatra was started. What do I miss here?

UPD: moving the require helper after the .app = is probably more correct but still no effect.

Please next time when opening an issue consider opening a discussion, because issue doesn't assume a question.

This is a working one file example, that can be run as ruby file_name.rb with rspec which can easily be replaced with minitest.

require "bundler/inline"

gemfile do
  source "https://rubygems.org"

  gem "puma"
  gem "rspec"
  gem "capybara"
  gem "cuprite"
  gem "ferrum"
  gem "sinatra"
end

require "rspec/autorun"
require "capybara/rspec"
require "capybara/cuprite"
require "sinatra/base"

class MyApp < Sinatra::Base
  get "/" do
    DATA
  end
end

Capybara.app = MyApp
Capybara.default_driver = :cuprite
Capybara.register_driver :cuprite do |app|
  Capybara::Cuprite::Driver.new(app)
end

describe "flaky spec", type: :feature do
  let(:email) { "[email protected]" }
  let(:first_name) { "Firstname" }
  let(:last_name) { "Lastname" }

  it "submits form successfully" do
    visit "/"

    fill_in "email", with: email
    click_button("Next")

    sleep 1

    fill_in "first-name", with: first_name
    fill_in "last-name", with: last_name
    click_button("Finish")

    expect(page).to have_text("Successfully sent")
  end
end

__END__

        parent = event.target.parentElement;
        parent.classList.remove("active");
        parent.nextElementSibling.classList.add("active");
      });
