ChromeDriver 2.23

ChromeDriver 2.22

Changes include many bug fixes, particularly for Chrome 51+. This includes fixes for various scenarios that caused ChromeDriver to timeout and/or hang.

ChromeDriver 2.21

Changes include numerous bug fixes, and improved support for recent versions of Chrome. A few changes were made to bring ChromeDriver in line with other WebDriver implementations, and may break some existing tests:
  • Calls to GetTitle will now return a blank string if the page has no title. Previous versions returned the URL of the page in this case. Tests that need to check for the URL should do so explicitly.
  • Calls to GetUrl will now return the URL of the top-level browsing context, rather than the URL of the current frame. This matches what is shown in the browser's address bar, and tests that need to check for the URL of the frame can evaluate the JS expression window.location.href.

ChromeDriver 2.20

Fixed bugs:

  • Getting the location of an element, and moving the mouse to an element, now uses the center of the first ClientRect, rather than the center of the bounding box.
  • Closing a Chrome session with a custom user data directory now uses SIGTERM on POSIX, which ensures that the browser updates any preferences and settings in the profile directory after the test completes.
