---------------------------------------
Summary: Tests needed to improve code coverage in Rules.scala
Key: DAFFODIL-2515
URL: https://issues.apache.org/jira/browse/DAFFODIL-2515
Project: Daffodil
Issue Type: Improvement
Components: Clean Ups, QA
Affects Versions: 3.1.0
Reporter: Mike Beckerle
Recent changes to address DAFFODIL-1437 (a cleanup) in Rules.scala showed that
there are many test code coverage gaps. (CodeCov shows them in the changes in
PR [https://github.com/apache/daffodil/pull/561] )
These specific code coverage gaps are of particular concern, as this is the
lexical analyzer code for Daffodil's recognizing of escapes, delimiters, etc.
This area needs to be well covered.
TDML Tests of real DFDL schemas and test data need to be created which create
the subtle DFDL scenarios which cause all these variations to be explored and
covered. If it turns out there is code here that is unreachable by way of
actual DFDL parsing, then we should remove it and document why.
( Note that we could get the code coverage by just writing Junit tests that
exercise these classes/objects directly. But we should *not* do that. The point
is to create DFDL which causes this to be exercised when tested. )
