Hier wird die Klasse TTestSetup erwähnt:
http://dunit.sourceforge.net/README.html#_Extensions
Zitat:
TTestSetup can be used when you wish to set up state exactly once for a test case class (the SetUp and TearDown methods are called once for each test method). For example, if you were writing a suite of tests to exercise some database code, you might subclass TTestSetup and use it to open and close the database before executing the suite.
