Do you know Playwright?
It is faster and newer than Selenium and has a clearer syntax than Capybara-DSL, see Discussion.
Attention Playwright can be used with Capybara DSL, which would sound good for existing projects. But, at least in my tests, it was not possible to configure it so that existing specs written in Capybara-DSL could persist. I had to rewrite them.
Playwright within Rails/RSpec
Derived from Docs
Setup
- Remove all Selenium-gems
- add gem
capybarawithin grouptest - add gem
playwright-ruby-clientwithin grouptest -
npm i --save-dev playwright(unlike docs do not install it bynpx i ...because it would not install dependencies)
a File like playwright_helper
require 'rails_helper'
require 'capybara'
require 'playwright'
RSpec.configure do |config|
# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
# Docs https://playwright-ruby-client.vercel.app/docs/article/guides/rails_integration_with_null_driver
# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
video_dir = '/tmp/rails-system-test-videos'
config.before :all, type: :system do
FileUtils.rm_rf(video_dir)
FileUtils.mkdir(video_dir)
end
class CapybaraNullDriver < Capybara::Driver::Base
def needs_server?
true
end
end
Capybara.register_driver(:null) { CapybaraNullDriver.new }
config.around(driver: :null) do |example|
driven_by :null
Playwright.create(playwright_cli_executable_path: './node_modules/.bin/playwright') do |playwright|
playwright.chromium.launch(headless: true) do |browser|
browser.new_context(
record_video_dir: video_dir,
baseURL: Capybara.current_session.server.base_url
) do |context|
# for requests this timeout can be too short, but for most steps it should be good
# You can increase this in every selector on the test
context.set_default_timeout(1500.0)
@page = context.new_page
# custom login process
page.goto('/login-page', timeout: 50000) # first load may last longer
...
example.run
end
if passed?
FileUtils.rm(page.video.path)
else
puts "file://#{page.video.path}"
end
end
end
end
end
and a test:
require 'playwright_helper'
RSpec.describe "pw", type: :system, driver: :null do
let(:page) { @page }
it 'test' do
page.goto('/')
end
end
Here is a Code Example
