Learn Gherkin Scenarios
You've learned how to classify inputs and predict outcomes with the Test Case Generator. Now it's time to take the next step: expressing those test cases as structured scenarios in the language that bridges QA and development teams — Gherkin.
This module contains one lesson that explains how the Gherkin Scenario Builder works — its Given/When/Then structure, its dropdowns, and the techniques behind each case. Then a hands-on challenge puts you to work testing a real subtraction form.
What You'll Do in This Module
| # | Activity | Type | Time | XP |
|---|---|---|---|---|
| 1 | How the Gherkin Scenario Builder Works | Lesson | 10 min | 4 XP |
| 2 | Number Subtraction | Practice | 15 min | 8 XP |
Total: ~25 minutes · 12 XP
Module Goal
Work through the lesson, then complete all 7 test cases of the Number Subtraction challenge. When you finish, you'll earn the "Scenario Architect" badge — proof that you can read a Gherkin scenario, select the right values, and predict what a real application will do.
Why This Matters
Gherkin is the language of BDD — Behaviour-Driven Development. It lets testers, developers, and business stakeholders describe the same behaviour in a shared format. Learning to read and construct Gherkin scenarios is one of the most transferable skills a QA engineer can have.
The theory behind BDD — how to write scenarios from requirements, how teams collaborate around them — will be covered in depth in future courses. For now, your goal is to build the instinct by doing.
