Test package: daffodil.section23.dfdl_expressions
Test Case: test_expression_bad_path_to_variable()

Description: While testing expressions in a schema I got a exception stating "daffodil.exceptions.Abort: Must use inside of withParseErrorThrowing construct"

This message is displayed when I have a malformed path in the pression that should cause an error. Regardless of the presence of the <errors></error></errors> block the test fails. This test case also caused https://opensource.ncsa.illinois.edu/jira/browse/DFDL-345

The inability to test error handeling in expressions limits what errors can be discovered in the code.
