Which wca4z capability helps accelerate creation of test cases for generated Java modules?

Think of it like working hands-on with IBM mainframe systems — the answer here is 'wca4z can automatically deploy generated Java to a test LPAR and execute the original COBOL regression suite'. wca4z can generate JUnit test stubs based on the COBOL program structure and the defined service interface, giving developers a starting scaffold that they complete with test data and assertions. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.
