ruby capybara::expectationnotmet:等待selenium会话重置失败/错误时超时

我不断地在ci上出现片状错误,而我的selenium会话没有重新启动。我在本地运行测试时没有这个问题。它只发生在我的ci服务器上。

我使用的是capybara 2.18.0、rspec 3.7.0、sleniumwebdriver3.9.0和site2.13。有

Capybara::ExpectationNotMet: Timed out waiting for Selenium session reset
Failure/Error: raise Capybara::ExpectationNotMet.new('Timed out waiting for Selenium session reset') if (Capybara::Helpers.monotonic_time - start_time) >= 10

我的 spec_helper.rb 看起来像这样:

require 'rspec'
require 'capybara/rspec'
require 'capybara-screenshot/rspec'
require 'capybara/dsl'
require 'selenium-webdriver'
require 'site_prism'

Capybara.register_driver :selenium do |app|
  Capybara::Selenium::Driver.new(app, browser: :chrome)
end

Capybara.save_path = "#{Dir.pwd}/screenshots"

Capybara.default_driver = :selenium

Capybara.app_host = ENV['url']

if ENV['timeout']
  Capybara.default_max_wait_time = ENV['timeout'].to_i
else
  Capybara.default_max_wait_time = 15
end

RSpec.configure do |config|
  config.full_backtrace = true

  config.before(:each) do
    config.include Capybara::DSL
  end

  config.after(:each) do |example|
    if example.exception
      name = example.example_group.to_s
      name.slice!('RSpec::ExampleGroups::')
      name.gsub!('::', '#')
      whole_page.save_screenshot("#{name}##{example.description.tr(' ', '_')}-#{Time.now.strftime('%H_%M_%S')}.png")
    end
  end
end
