Prerequisites for Replaying Tests with Google Chrome

Command-line parameters

When you use Google Chrome to replay a test or to record locators, Google Chrome is started with the following command:

%LOCALAPPDATA%\Google\Chrome\Application\chrome.exe
  --enable-logging
  --log-level=1
  --disable-web-security
  --disable-hang-monitor
  --disable-prompt-on-repost
  --dom-automation
  --full-memory-crash-report
  --no-default-browser-check
  --no-first-run
  --homepage=about:blank
  --disable-web-resources
  --disable-preconnect
  --enable-logging
  --log-level=1
  --safebrowsing-disable-auto-update
  --test-type=ui
  --noerrdialogs
  --metrics-recording-only
  --allow-file-access-from-files
  --disable-tab-closeable-state-watcher
  --allow-file-access
  --disable-sync
  --testing-channel=NamedTestingInterface:st_42

When you use the wizard to hook on to an application, these command-line parameters are automatically added to the base state. If an instance of Google Chrome is already running when you start testing, without the appropriate command-line parameters, Silk Test Classic closes Google Chrome and tries to restart the browser with the command-line parameters. If the browser cannot be restarted, an error message displays.

Note: The command-line parameter disable-web-security is required when you want to record or replay cross-domain documents.

Note: To test a web application that is stored in the local file system, navigate to the chrome://extensions in Google Chrome and check the Allow access to file URLs check box for the Silk Test Chrome Extension.
