Your First Guided Tests

A good tester always understands the tool before touching the target. This module gives you that understanding — and then puts it immediately to use.

Start with the lesson: it walks you through the entire challenge interface using Number Addition as a concrete example. Once you know the mechanics, the four practice challenges will feel straightforward.

What's in this module

1. How Challenges Work in BugEater — The complete walkthrough: progress circles, test case cards, input fields, feedback, and the XP + badge reward at the finish line.

Then, four Guided Testing Challenges:

2. Number Addition — 6 test cases. A two-field addition form with basic inputs, negatives, decimals, invalid data, and overflow.
3. Divider — 6 test cases. A division form including a division-by-zero edge case.
4. Password Restore — 11 test cases. A password validation form that covers length, character mix, and special rule combinations.
5. Update Nickname — 6 test cases. A profile update form with three fields: nickname, first name, and last name.
