Run pytest tests, read a failure and fix a simple defect
Understand why developers test, run a pytest suite, read a failure (the test, the expected value, the actual value), fix the code and not the test, run it again, add a test by copying a model, and reproduce a bug with a test before fixing it.

Beyond the lessons
Assess, practise, pass the proof
Reading a lesson confirms nothing. A skill is confirmed by a passed quiz, practised in a guided lab, and put to the test by a challenge or a mission; an imported lab result is not verified by the site.
Assess yourself
2 quizzes
At the end of the lessons: passed at 70%, they confirm the skill.
Practice
2 guided labs
Proof
1 practical proof
A practical proof is a challenge, a capstone or a declared lab.
Used by the mission “Ship an internal tool to other teams”, which has its proof.
