In the Validate phase, integration testing of generated Java modules specifically verifies what?

Think of it like working hands-on with IBM mainframe systems — the answer here is 'That the generated Java source compiles without warnings using the strictest compiler flags'. Integration testing validates that the combined behavior of multiple generated Java modules in a realistic end-to-end scenario matches expected business outcomes, catching interaction defects that uni. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.
