Headless mode in cucumber capybara ruby automation - ruby

Question

I have seeing a lot of similar question, but non of them have help me to understand.
how to run my .feature file in headless mode using chromedrive, selenium, capybara, ruby and cucumber.
this is my env.rb:
require_relative 'helper.rb'
BROWSER = ENV['BROWSER']
World(Helper)
Capybara.register_driver :selenium do |app|
if BROWSER.eql?('chrome_headless')
Capybara::Selenium::Driver.new(app,
:browser => :chrome,
:desired_capabilities => Selenium::WebDriver::Remote::Capabilities.chrome(
'chromeOptions' => {
'args' => [ "headless", "window-size=1440x768", "disable-gpu"]
}
)
)
elsif BROWSER.eql?('chrome')
Capybara::Selenium::Driver.new(app,browser: :chrome)
end
end
Capybara.configure do |config|
config.default_driver =:selenium
Capybara.page.driver.browser.manage.window.resize_to(1440,768)
end
Capybara.default_max_wait_time = 60
this is my helper.rb:
module Helper
def take picture(file_name, res)
file_path = "reports/screenshot/"
dateTime = DateTime.now.to_s
dateTime.split(':')
date = dataHora[0..12].to_s+dataHora[14..15].to_s+dataHora[17..21].to_s
picture = "#{file_path}#{date}#{nome_arquivo}-#{res}.png"
temp_shot = page.save_screenshot(picture)
shot = Base64.encode64(File.open(temp_shot, "rb").read)
attach(shot, 'image/png')
end
end
this is my step_definition file .rb
just a normal rb file containing capybara elements
adm = LoginAdmin.new
admInic = TelaInicialAdmin.new
varGlobal = YAML.load(File.read('./configuracoesGlobaisTeste.yaml'))
#nomeOferta = varGlobal["nomeOferta"]
#nomeProduto = varGlobal["nomeProduto"]
Dado('que acessei a página da Vivo') do
acesso.load
end
Quando('clicar em Entrar posso digitar minhas credenciais ') do
page.driver.browser.navigate.refresh
sleep 3
inicio.btnEntrar.click
inicio.usuario.set #usuario
inicio.senha.set #senha
inicio.btnAcessarConta.click
end
is there missing something?
this is how i run the automation on terminal using the tag in my feature file:
cucumber -t#criarClienteCompraLojaClone
this command opens a browser using a GUI. i wish not open GUI. I wish to perform a headless test.
i have just try every tutorial in stackoverflow and google.
Please any suggestion will help!

My headless works updating the env.rb file for this:
require_relative 'helper.rb'
BROWSER = ENV['BROWSER']
#HEADLESS
World(Helper)
Capybara.register_driver :headless_chrome do |app|
Capybara::Selenium::Driver.new(app, browser: :chrome,
options: Selenium::WebDriver::Chrome::Options.new(args: %w[headless no-sandbox disable-gpu]))
end
Capybara.configure do |config|
config.default_driver =:headless_chrome
#Capybara.page.driver.browser.manage.window.resize_to(1440,768)
end
Capybara.default_max_wait_time = 60
