----------------------------------------
Summary: TDML runner - throws exception if missing root attribute
with negative test case
Key: DAFFODIL-2734
URL: https://issues.apache.org/jira/browse/DAFFODIL-2734
Project: Daffodil
Issue Type: Bug
Components: TDML Runner
Reporter: Steve Lawrence
The "root" attribute of a parser/unparserTestCase is normally optional and is
not required for positive test cases because the TDML runner just infers it
from the expected infoset. But if a test case is negative, then there is no
expected infoset and the root attribute is mandatory. However, if you
accidentally leave off the root attribute, you get an unhelpful abort exception:
{code}

name. Namespace argument was: Some(http://example.com)

Instead we should get an error about a missing root attribute.
