Interface for listeners which are interested when properties are expanded.
WebTest reports contain the expanded form of properties (ie "foo" instead of "${myProp}")
but Ant doesn't offer any mean to know how properties have been expanded.
WebTest custom PropertyHelper
WebtestPropertyHelper will notify build listeners
implementing
IPropertyExpansionListener of property expansion.
Helper class for working with Ant and WebTest dynamic properties.
This property helper is registered at the start of a WebTest and used by ant to evaluate
properties when configuring tasks.
It is able to evaluate traditional Ant properties like ${my.property} as well as
WebTest dynamic properties like #{my.dynamic.property}.
It will notify build listeners implementing
IPropertyExpansionListener of the property expansion.
