I think the DFDLTestSuite constructor can't stay deprecated. We still need to
construct them.
It can become package private I think, so not usable outside the package. I
think the scala syntax for that is:
class Foo private[pkgName] (arg1: Type1, arg2: Type2) { ...
}
The deprecation was just to help in hunting down the usages.
If we need more Runner functions that's ok. But probably we can just depend on
Scala's ability to pass arguments by specifying the argument names explicitly
and getting defaults for the rest. I think calls to Runner already do this in
many cases.

Subject: Daffodil-1300
Regarding DAFFODIL-1300, I’m hunting down usage of “new DFDLTestSuite” and
replacing them with usage of the “Runner” object. In order to help identify
where the DFDLTestSuite was being invoked, I un-commented:
daffodil-tdml-lib/src/main/scala/org/apache/daffodil/tdml/TDMLRunner.scala line
198
@deprecated("2016-12-30", "Use Runner(...) instead."
This revealed that the Runner object itself invokes “new DFDLTestSuite” when
the runOneTest function is called. This seems to defeat the purpose of this
task. I’m hoping for some guidance or opinions on when, if ever, it’s
appropriate to invoke the DFDLTestSuite constructor.
Related to this – I believe I’ll need to create more constructors for the
Runner object in order to preserve the argument combinations currently invoked
by some of the new DFDLTestSuite calls – in particular when compileAllTopLevel
must be provided as true when paired with an xml node instead of a file name.
Is deprecating the DFDLTestSuite constructor still appropriate, or since this
ticket was written have we changed or strategy such that it shouldn’t be called
directly, but will need to be used by the Runner object?
