Ruby - Capybara 录制测试执行视频

Question

我正在尝试使用 Capybara 以视频格式记录和保存我的执行测试。我的测试通过了，但是我的 Mac 终端出现了几个错误。此外，视频没有被录制/保存。

SPEC_HELPER.RB

require 'capybara'
require 'capybara/rspec'
require 'capybara/dsl'
require 'selenium-webdriver'
require 'headless'

headless = Headless.new
headless.start

RSpec.configure do |config|

  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end

  config.shared_context_metadata_behavior = :apply_to_host_groups
  config.include Capybara::DSL

  config.before(:example) do
    headless.video.start_capture
    page.current_window.resize_to(1200, 800)
  end

  config.after(:example) do |e, scenario|
      name = e.description.gsub(/[^A-Za-z0-9 ]/, '').tr(' ', '_')
      d = Time.now.strftime("%F-%T")
      page.save_screenshot('log/' + name + '-' + d.to_s + '.png')

      headless.video.stop_and_save('log/' + name + '-' + d.to_s + '.mov')
  end

end

Capybara.configure do |config|
  config.default_driver = :selenium_chrome_headless
  config.run_server = false
end

Capybara.default_max_wait_time = 10

Answer 1

尝试替换这些行

page.save_screenshot('log/' + name + '-' + d.to_s + '.png')
headless.video.stop_and_save('log/' + name + '-' + d.to_s + '.mov')

与

#please note for this ../ from this file to root just reach to root of the project. in my case root 

root_path = File.join(File.dirname(__FILE__), "../")

page.save_screenshot(File.join(root_path,'log/' + name + '-' + d.to_s + '.png'))
headless.video.stop_and_save(File.join(root_path,'log/' + name + '-' + d.to_s + '.mov'))
