A Guided Testing Challenge is an interactive exercise where you play the role of a tester — but without any guesswork. Every step is described for you. Your only job is to follow the instructions on screen, fill in the right values, and click the button.
There is no room for creative choices here. No keyboard shortcuts, no workarounds. Just: read, input, verify.
Learning Objectives
By the end of this lesson you will be able to:
- Describe the layout of a Guided Testing Challenge
- Read a test case card and identify where each value goes
- Interpret success and error feedback correctly
- Explain when XP and badges are awarded
The Challenge Interface
When you open a challenge, you see four things:
- Progress circles at the top — numbered 1, 2, 3... N. Each circle represents one test case. The highlighted circle shows your current case; filled circles are already done.
- The test case card — a box that specifies exactly which values to enter and what the expected result should be.
- Input fields — one or more labelled text fields where you enter the values from the test case card.
- The action button — labelled "Calculate", "Verify", or similar depending on the challenge.
You must follow the test case card precisely. Do not change the values, do not add spaces, do not interpret — just type exactly what you see and click the button.
Let's Walk Through It: Number Addition, Case 1
The Number Addition challenge has 6 test cases. Open it and you will see 6 empty circles at the top of the page.
The first test case card shows three numbers:
- First number: 1
- Second number: 2
- Expected result: 3
This is a complete specification. Here is what to do:
- Find the "First number" input field on the page.
- Type 1 into it.
- Find the "Second number" input field.
- Type 2 into it.
- Click the "Calculate" button.
That is it. You have just executed a test case.
Reading the Feedback
After you click "Calculate", one of two things happens:
Correct submission: A success message appears, circle №1 fills in, and the challenge automatically advances to case №2.
Incorrect submission: The field containing the wrong value is highlighted in red, and an error message explains what went wrong. Some challenges highlight individual fields, so you can see exactly which one needs fixing. Correct the value and try again.
Completing All Cases
Work through the cases one by one. Once all circles are filled, the challenge is complete.
At that moment BugEater automatically awards you:
- XP — added to your total immediately.
- The challenge badge — a unique badge for each completed challenge, shown on the completion banner.
XP is awarded once, at the very end. There are no partial awards per case.
The 4 Challenges That Await You
After this lesson you will find four Guided Testing Challenges in this module:
- Number Addition — 6 cases: basic arithmetic, negative numbers, decimals, invalid input, and overflow.
- Divider — 6 cases: basic division, negative results, decimal output, invalid input, and division by zero.
- Password Restore — 11 cases: a password validation form with rules for length, character mix, and allowed characters.
- Update Nickname — 6 cases: a profile update form with three fields — nickname, first name, and last name.
Each challenge tests a different form, but the mechanics are always the same: read the test case, fill in the values, click the action button, read the feedback.
Testing theory — boundary values, equivalence partitions, and all that — is covered in dedicated Trails. This module is purely about getting comfortable with the challenge mechanics.
Pro Tips
Enter values exactly as shown. The test case specifies the precise value. A trailing space or a capital letter where none is expected will give you an incorrect result.
XP is awarded once. Complete all cases and you earn the full XP reward. There are no partial rewards — finish line only.
Stuck on a case? Re-read the test case card carefully. Everything you need is there.
Summary
A Guided Testing Challenge gives you a numbered set of test cases and a form. Your job: for each case, enter the specified values into the correct fields and click the action button. Correct submissions fill the progress circle and advance you to the next case. Complete all cases to earn your XP and badge.
Now close this lesson and open the first challenge.
