Selenium :: WebDriver :: Error :: ElementNotVisibleError：使用Chrome浏览器时调用send_key函数时看不到元素。

Selenium::WebDriver::Error::ElementNotVisibleError: element not visible

我正在并行运行ruby selenium脚本，并在通过send_key将文本输入发送到网页时面临以下问题。

Im using following versions:
(Session info: chrome=43.0.2357.125)
(Driver info: chromedriver=2.15.322448 (52179c1b310fec1797c81ea9a20326839860b7d3),platform=Linux 3.2.0-29-generic x86_64)

以下是我的代码片段：

class MyClass
dir="xyz"
 @headless = Headless.new(display: 100, reuse: true, destroy_at_exit: false).start
Selenium::WebDriver::Chrome.driver_path = "/home/ubuntu/chromedriver"
    @driver = Selenium::WebDriver.for :chrome, :switches => %W[--ignore-certificate-errors --enable-logging --user-data-dir=#{dir} --disable-popup-blocking --disable-translate --use-fake-ui-for-media-stream --use-file-for-fake-audio-capture=song.wav --use-file-for-fake-video-capture=city_cif_15fps.y4m --use-fake-device-for-media-stream]
 @driver.get(@base_url + "/#{$url}/")
      wait = Selenium::WebDriver::Wait.new(:timeout => 90) # seconds
      wait.until {
        @driver.find_element(:id, "join-dialog-join")}
      x=@driver.find_element(:id, "join-dialog-input-name")
      @driver.execute_script("document.getElementById('join-dialog-input-name').style.visibility='visible';")
      @driver.execute_script("document.getElementById('join-dialog-input-name').removeAttribute('hidden');")
      #@driver.save_screenshot("Join-display_login_#{DateTime.now.to_s}_1_#{$epname}.png")
      #puts x.attribute("innerHTML")
      @driver.find_element(:id, "join-dialog-input-name").send_key "#{$epname}"
end

我试过让元素可见，我也尝试删除属性隐藏，如果碰巧是这样的话。我也尝试使用JS而不是send_keys，但似乎没有帮助。

@driver.execute_script("document.getElementById('join-dialog-input-name').value='Nikhil';")

任何帮助将不胜感激!!。

Xvfb会导致这种情况吗？控制台日志

建议使用以下内容

[5245:5245:0626/181715:ERROR:chrome_browser_main_extra_parts_x11.cc(56)] X IO error received (X server probably went away)
[5280:5280:0626/181715:ERROR:x11_util.cc(82)] X IO error received (X server probably went away)

注意：只有当我并行启动脚本时才会出现此问题。

我认为问题是在Chrome的默认视图框中确实看不到元素。（并且在默认窗口大小中无法显示）

要通过webdriver设置窗口大小，你可以做一些事情，比如browser.manage().window().setSize(1200,1100);（这是在javascript下。我觉得它在ruby下看起来很相似）

在没有Xvfb的无头模式下使用chrome（自V59起）。另请参阅此帖子https://stackoverflow.com/a/46299332/2718002
