水豚铬无头确认对话框

Question

我正在尝试在 rspec Ruby on Rails 中使用带有水豚/硒的无头铬模式，并在尝试单击确认对话框时出现错误

Capybara.register_driver(:headless_chrome) do |app|
capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
chromeOptions: { args: %w[headless disable-gpu test-type window-size=1920x1080] }
)
driver = Capybara::Selenium::Driver.new(
app,
browser: :chrome,
desired_capabilities: capabilities
)
driver
end
Capybara.server = :puma
Capybara.javascript_driver = :headless_chrome

scenario 'delete movie' do
login_as user
visit edit_public_movie_path(movie)
expect(page).to have_selector('span[ng-click="ctrl.deleteMovie()"]')
find('span[ng-click="ctrl.deleteMovie()"]').click
page.driver.browser.switch_to.alert.accept
wait_for_ajax(wait_after: 1)
expect(page).to have_content('Click here to upload movie (Max: 500 MB)')
end

并得到此错误

Event movie success delete movie
Failure/Error: page.driver.browser.switch_to.alert.accept
Selenium::WebDriver::Error::NoSuchAlertError:
no alert open
(Session info: headless chrome=59.0.3071.115)
(Driver info: chromedriver=2.29.461585 (0be2cd95f834e9ee7c46bcc7cf405b483f5ae83b),platform=Mac OS X 10.12.5 x86_64)

使用共模，它可以正常工作。似乎硒不支持无头模式或需要其他方法来做到这一点。有什么想法吗？

所以，我花了很多时间寻找工作环境。

您需要最后构建 chromium，因为预览版本有一个错误。您可以通过这些脚本linux或Mac获得它

这是我的水豚配置

Capybara.register_driver(:headless_chrome) do |app|
capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
chromeOptions: {
args: %w[headless disable-gpu disable-popup-blocking no-sandbox window-size=1920x1920],
binary: "#{Dir.home}/chromium-latest-#{platrofm}/latest/#{chrome_file}"
})
driver = Capybara::Selenium::Driver.new(app,
browser: :chrome,
desired_capabilities: capabilities)
driver
end
Capybara.server = :puma
Capybara.javascript_driver = :headless_chrome
Capybara.default_max_wait_time = 20
Capybara.server_port = 55305
def platform
if /linux/ =~ RUBY_PLATFORM
"linux"
else
"macosx"
end
end
def platform_linux?
platform == "linux"
end
def chrome_file
if platform_linux?
"chrome"
else
"Chromium.app/Contents/MacOS/Chromium"
end
end

你应该使用page.driver.browser.switch_to.alert.accept而不是page.accept_alert

有同样的问题。请使用 chromeOptions 中的禁用弹出窗口阻止功能。
