Package org.jenkinsci.test.acceptance.selenium

Class Scroller

java.lang.Object
org.jenkinsci.test.acceptance.selenium.Scroller
All Implemented Interfaces:
org.openqa.selenium.support.events.WebDriverListener
public class Scroller extends Object implements org.openqa.selenium.support.events.WebDriverListener
Automatically scrolls the element into view.

Especially in the configuration page, the floating DIVs at the top and the bottom of the pages can interfere with WebDriver trying to click the elements underneath it.

At least on Chrome (and possibly in other browsers), trying to interact with an element when it's below another element causes the following error: 

 
 Tests run: 3, Failures: 0, Errors: 2, Skipped: 0, Time elapsed: 227.711 sec <<< FAILURE! - in plugins.AntPluginTest
 autoInstallAnt(plugins.AntPluginTest)  Time elapsed: 73.932 sec  <<< ERROR!
 org.openqa.selenium.WebDriverException: unknown error: Element is not clickable at point (506, 967). Other element would receive the click: <div class="bottom-sticker-inner">...</div>

This work around simply tries to scroll the element into a view before we interact with this. Originally developed in Ruby version of selenium-tests in lib/jenkins/capybara.rb.

      public void afterGet(org.openqa.selenium.WebDriver driver, String url)
      Specified by:

    • disableStickyElements

      public void disableStickyElements()
      Sometimes sticky elements (elements that are fixed in position on the page, such as the bottom app bar), appear on top of other elements, making those elements inaccessible. This method removes the sticky nature of these elements meaning that they'll no longer appear on top of other elements.

    • scrollIntoView

      public void scrollIntoView(org.openqa.selenium.WebElement e)
      The framework is expected to take care of the correct scrolling. When you are tempted to scroll from PageObjects or tests, there is likely a framework problem to be fixed.
