What Testers DoWTD
For new and junior QA engineers

Hands-on QA practice with real feedback

Test a realistic practice app with hidden bugs, starting with a hotel booking site. Write a bug report for each one you find, and get it scored with written feedback on what to improve.

Free to use. No card needed.

How it works

  1. Test the hotel app

    Each mission gives you a brief and part of the spec. Explore the practice hotel site and look for where it doesn't match. Nothing there is real: no real hotels, payments or emails.

  2. Write a bug report

    Give it a title, steps to reproduce, the expected result and the actual result, the same way you would at work.

  3. Get feedback and revise

    Your report is scored out of 100 with written feedback. Revise it and see how much clearer it gets.

What you're graded on

Every report is scored against the same four things a team lead looks for.

Clear title

20 pts

Someone can tell what's wrong, and where, from the title alone.

Steps to reproduce

30 pts

Numbered, complete steps that let anyone see the bug for themselves.

Expected vs actual

25 pts

What should happen, what happened instead, and the difference between them.

Evidence and environment

25 pts

The data you used, the hotel date and anything else needed to see it again.
