pySHACL: failure to report validation errors

I have a gist with all of the relevant files at: https://gist.github.com/James-Hudson3010/2588d9b17dd33e15922122b8b5cf1bd7

If I execute:

$ pyshacl -a -f human employees.ttl

I get the following, correct validation report...

Validation Report
Conforms: False
Results (3):
Constraint Violation in MaxInclusiveConstraintComponent (http://www.w3.org/ns/shacl#MaxInclusiveConstraintComponent):
    Severity: sh:Violation
    Source Shape: hr:jobGradeShape
    Focus Node: d:e4
    Value Node: Literal("8", datatype=xsd:integer)
    Result Path: hr:jobGrade
Constraint Violation in DatatypeConstraintComponent (http://www.w3.org/ns/shacl#DatatypeConstraintComponent):
    Severity: sh:Violation
    Source Shape: hr:jobGradeShape
    Focus Node: d:e3
    Value Node: Literal("3.14", datatype=xsd:decimal)
    Result Path: hr:jobGrade
Constraint Violation in MinCountConstraintComponent (http://www.w3.org/ns/shacl#MinCountConstraintComponent):
    Severity: sh:Violation
    Source Shape: hr:jobGradeShape
    Focus Node: d:e2
    Result Path: hr:jobGrade

However, if I split employees.ttl into three files containing the schema, shape, and instance data and run:

pyshacl -s shape.ttl -e schema.ttl -a -f human instance.ttl

the result is:

Validation Report
Conforms: True

I assume I am calling pyshacl correctly.

Solution

When you use the individual files, pySHACL has no way of knowing what to associate your Shape file's hr:Employee NodeShape with. It seems to know when it's in that single file (perhaps it runs against all classes in the file??).

So:

rename the Employee shape to not overload the hr:Employee class name: hr:EmployeeShape
add back in the sh:targetClass directive:

hr:EmployeeShape
   a sh:NodeShape ;
   sh:targetClass hr:Employee ;
   sh:property hr:nameShape ;
   sh:property hr:jobGradeShape .

Then the multi-file call gives the same result as the single file call.

Your calls to pySHACL are correct!
