Maybe I'm on the wrong track, but there are currently 2 modules (agents |
pull-agent) containing 3 individual test cases (Derby, HSQLDB, postgresql).
In maven I run the test for the agents module and I thought I would end up
with 3 "Configuration file successfully read" messages, because each Test
would like to create its own properties files.
So, for building the framework with ant I supposed ending up with 6
"Configuration file successfully read" messages.

Let's take as example the
org.apache.manifoldcf.agents.tests.SanityPostgresqlTest of the agents
module.
On the localSetUp method of the parent class
(org.apache.manifoldcf.core.tests.BasePostgresql) is
org.apache.manifoldcf.core.database.DBInterfacePostgreSQL as database
implementation class defined.
I supposed to see this class name as implementationClass output in my
previous message.
