Module 21 · AI-Assisted Development & Testing

Beyond the 1Z0-830 exam

This is the capstone — the project's reason for being. AI assistants now write a large share of day-to-day Java and tests. Using them well means knowing how to prompt for good output, review it critically, and put guardrails around what you ship. Everything in this course — Java fluency, testing, design sense — is what lets you judge AI output instead of trusting it.

Using AI well, and verifying what it produces: effective generation workflows, critically reviewing output, prompt patterns and test oracles, and the guardrails that decide when not to trust AI.

Lab policy

This module's lab is green by default: it pairs plausible-looking "AI-generated" methods (with real, subtle bugs) against the reviewed versions, and the test is the oracle that exposes the difference. It's the whole module in code — generated ≠ correct until verified.

Lessons

#	Lesson	What it covers
01	Generating Code & Tests with AI	Effective workflows, scaffolding, refactoring.
02	Critically Reviewing AI Output	Wrong idioms, hallucinated APIs, subtle bugs.
03	Prompt Patterns & Test Oracles	Specifying intent, deriving oracles, edge cases.
04	Guardrails — When Not to Trust AI	Verification, coverage, determinism, human review.
