When writing the testcase for my selector I missed some functionality in
BaseSelectorTest:
- transfering properties from JUnit test class to the Ant test project
- resolve the selection String ("TTTTT..FF") to filenames
I have done that with a local org.apache.tools.ant.BuildFileTest class (like
the TaskdefForMakingBed).
Should I put that in the BaseSelectorTest class?

bft.writeProperties("f2name="+f2name);
bft.writeProperties("f3name="+f3name);
bft.writeProperties("f4name="+f4name);
// call the target for making the files dirty
bft.doTarget("cacheselectortest-makeDirty");
