我已经以更简单的方式复制了这个问题。
HTML：
<html>
<head>
<script src="../../../libs/jquery-1.11.3.min.js"></script>
</head>
<body>
<div id="abc" style="width:100px;height:100px;background-color:green;"></div>
<script type="text/javascript">
$("#abc").on('click', function() {
alert('clicked');
});
</script>
</body>
</html>
红宝石：
require 'selenium-webdriver'
profile = Selenium::WebDriver::Firefox::Profile.new
options = {}
options[:profile] = profile
driver = Selenium::WebDriver.for :firefox, options
driver.manage.timeouts.implicit_wait = 10
driver.navigate.to("the_above_html_file")
driver.action.move_to(driver.find_element(:id, "abc")).click.perform
当 Ruby 运行时，JavaScript 警报没有按预期打开；相反，Ruby 会生成此堆栈跟踪：
"performActions"
/usr/local/rvm/gems/ruby-2.2.5/gems/selenium-webdriver-3.4.0/lib/selenium/webdriver/remote/response.rb:69:in `assert_ok': performActions (Selenium::WebDriver::Error::UnknownError)

为什么会失败？使用driver.find_element(:id, "id").click 定位元素按预期工作，因此它似乎与action 类有关。
使用 Webdriver 3.4.0 和 GeckoDriver 0.16.1 运行 Ruby 2.2.5。

使用 Webdriver 3.4.0 和 GeckoDriver 0.16.1 运行 Ruby 2.2.5。
正在进行验收测试：
element = @driver.find_element(:class, "ui-slider-handle")
@driver.action.drag_and_drop_by(element, 50, 0).perform
element 是由 jQuery UI Sliders 创建的可移动滑块 - 请参阅 https://jqueryui.com/slider/。我们正在使用版本jquery-ui-1.11.4.custom/jquery-ui.min.js。
当我手动使用滑块时，它可以正常工作，但验收测试会抛出：
TestDistanceSlider#test_store_container_and_markers_updated_when_slider_moved:
Selenium::WebDriver::Error::UnknownError: performActions

我们如何诊断引发 Selenium::WebDriver::Error::UnknownError: performActions 的原因？
我们已经尝试过这种解决方法，但它给出了同样的错误：
@driver.action.click_and_hold(element).move_by(100, 0).release.perform

嗨，当您决定使用 Ruby Selenium Binding 时，为什么不使用 WATIR，WATIR 是 Ruby Selenium Binding 的良好包装器。添加了许多额外的功能。
