How to make an InstalledBuild with Test packaging feature?

When make the InstalledBuild with default xml, there are only 3 packaging configurationes: DebugGame, Development and Shipping.

How can I change something, then the installbuild will get the Test packaging feature?


The configuration is in InstalledEngineBuild.xml. There is a line like this:

<Option Name="GameConfigurations" DefaultValue="DebugGame;Development;Shipping" Description="Which game configurations to include for packaged applications"/>

Add your favorite configuration inside DefaultValue.
