The test, in brief
CompletedThe task was completed.
The tested task was completed in this session. This result applies to the task below.
What we tried
Started the Python Fundamentals journey, completed the introductory activity, confirmed XP/progress persistence, opened the Hello World lesson, deliberately submitted wrong code, and verified Coddy rejected it with clear feedback.
The positives
What worked well
Clear beginner flow, polished interface, helpful explanations, working quiz/challenge validation, useful error feedback, and persistent progress tracking.
Worth knowing
What we noticed
Wrong output in the Hello World challenge was correctly rejected, and the feedback clearly stated the exact expected output.
XP and completion progress remained saved after returning to the Journey screen.
The introductory lesson allowed any valid output by design, while the next real coding challenge used strict expected output validation.
