Reporting Crashes

Derek Kastner edited this page · 5 revisions

The following problems generally mean that webkit_server has crashed:

  • WebkitNoResponseError
  • QCoreApplication::postEvent: Unexpected null receiver
  • All tests fail after a given test
  • WebkitInvalidResponseError with "Invalid command"
  • Errno::EADDRNOTAVAIL: Can't assign requested address

If you encounter one of these errors, please set your driver to to :webkit_debug and attach all output from your test to the issue. Without this output, we can't do much to fix your issue.

Capybara.javascript_driver = :webkit_debug

Crash Log

If you happen to be using a mac, your mac console may reveal interesting things if the problems that you are running into have caused thread crashes. You can access this on your mac within the /Applications/Utilities folder as the application "Console". Clear the console display and attempt to reproduce the problem. If your problem is causing threads to crash you should see a crash report within the "User Diagnostic Reports" section in the left hand nav bar after reproducing the problem.
