The CUnitSuite component defines a super class for all CUnit (Component Unit Test) components.
All CUnit components inherit from CUnitSuite. This component is not meant to be used directly but as a base for CUnit test cases.
CUnitSuite provides assert*() and fail*() methods to compare (and validate) expected vs. actual values on your test cases.
Refer to Oracle BPM Studio Help for details on how to create unit tests and CUnit test cases.
