Expected Result | ServiceLoader API
| 1 | Tests when there are no providers found by the ServiceLoader API due to missing or empty meta-inf file | No META-INF/Services/org.apache.daffodil.udf.UDFunctionProvider file on classpath of classLoader (CLI Test) |
“No user defined functions found.” error | | 2 | Tests when there is an error thrown from ServiceLoader API | META-INF/Services/org.apache.daffodil.udf.UDFunctionProvider file contains typo in class name |
“ServiceConfigurationError” error | Provider Class
| 3 | Tests when UDF Provider has no function classes | UDF with no call to setFunctionClasses initializing functionClasses to array of classes |
Warning: Provider Ignored...No function classes found | | 4 | Tests when UDF Provider has empty function class | UDF with call to setFunctionClasses initializing functionClasses to empty array of |
classesWarning: Provider Ignored...No function found |
| 5 | Tests when provider doesn’t implement UDFunctionProvider | UDF with Provider that doesn’t extend UDFunctionProvider class |

| 7 | Tests when function classes don’t |
Tests when function classes don’t | have annotations | UDF with function class that doesn’t have function class annotation |
Warning: Provider Ignored...Annotations missing for FunctionClass(es) | | 8 | Tests when function classes have empty/invalid annotation fields | UDF with function class that has annotation function with empty fields |
FunctionClass ignored: … “Annotation namespace field is empty or invalid.” and/or “Annotation namespace field is empty or invalid.” | | 9 | Tests when function classes have no evaluate function | UDF with function class whose method isn’t named “evaluate” |
“Missing evaluate method for function provided” error |
| 10 | Tests when function can’t be found | Function call from schema with no non either non existent namespace or name |
“Function not found” error |
Evaluate function
| 11 | Tests when function class have overloaded evaluate function | UDF with overloaded |
evaluate function“Only one method allowed per class” error |
| 12 | Tests when arguments number incorrect | Function call from schema with incorrect arg number |
IllegalArgumentException |
| 13 | Tests when argument types incorrect | Function call from schema with incorrect arg type |
IllegalArgumentException |
| 14 | Tests when argument types unsupported | Function call from schema with unsupported type (such as Calendar) |
“Unsupported object representation type” error | | 15 | Tests when return type unsupported | UDF with unsupported return type such as Array of Arrays |
“Unsupported object representation type” error | | 16 | Tests UDF with no args | UDF with no param and static return type |
Returns value of static return |
| 17 | Tests UDF with no return type | UDF with void return type |
Error: "Evaluate method for function provided cannot be void" |
