Learn Test Case Generator
You've already learned how Guided Testing Challenges work. Now it's time to meet your first real test subject: a multiplication form.
This module contains one lesson that explains how the Test Case Generator works — its interface, its feedback, and the testing techniques quietly powering its cases. Then a hands-on challenge puts you in the driver's seat.

Module Goal
Work through the lesson, then complete all 6 test cases of the Number Multiplication challenge. When you finish, you'll earn the "Test Case Architect" badge — proof that you can systematically classify inputs and predict what a real application will do with them.
Why This Matters
Knowing which inputs to test is half the job of a QA engineer. The Test Case Generator teaches you to think in categories: valid inputs, invalid inputs, edge cases, and the unexpected. These are the building blocks of every test suite you'll ever write.
Testing theory — equivalence partitioning, boundary value analysis, and more — will be covered in depth in future courses. For now, your job is to build the instinct by doing.
