Test unpublished rules from your console if you use Akamai hosting.
The Switcher plug-in is often the easiest way to test. See Search Discovery plug-ins in the Dynamic Tag Management Product Documentation for more information.
The following steps show how to test without using the Switcher plug-in:
Access your web console on your site and type
_satellite.setDebug(true), then press Enter.
Refresh the page.
This action loads your staging library and sets the debugger, so that you can see details of all available (published / unpublished) rules firing on the page.
When finished, run
localStorage.setItem('sdsat_stagingLibrary', false), then press Enter.
