Also here is a list of chrome command line arguments chrome command line args The args parameter is for a list of command line switches to be used when starting the browser. There are two excellent resources for investigating these arguments: Chrome Flags for Tooling; List of Chromium Command Line Switches; Commonly used args include -start-maximized, -headless=new and -user-data-dir= GN args as used on this page are not the command line arguments passed to GN. They refer to the individual variables that are passed as part of the -args command line flag and/or written to the args.gn file.

You can start serverwith testpages filters pointing to specific domain:SITE_URL= python3 ../cms/runserver.py --port 5001If you wish to test Domain Wildcard scenario locally, you need tostart browser from command line and map ports to local.abptestpages.org (filters are alreadypointing to this domain).This works for Chromium browser only (excute command on the folder where browser binaryis).On Mac:open Chromium.app --args --host-resolver-rules="MAP local.abptestpages.org localhost:5001"On Linux:You may need to use chromium or google-chrome based on your distribution.chromium --args --host-resolver-rules="MAP local.abptestpages.org localhost:5001"On Windows:For a default installation on a 64-bit system.start "" "C:\Program Files\Google\Chrome\Application\chrome.exe" --host-resolver-rules="MAP local.abptestpages.org localhost:5001"Local page tests runIt may be useful to run page tests outside docker, for debugging purposes.Besides having both CMS and endpoint servers running, the test runner expects anunpacked ABP extension to be located in the ./testext folder.
