One question.
See how you think.
This is the style of every question in the assessment: real situations, not trivia, with an explanation for each answer. The full test covers 28 questions across 7 skills.
A test passes on its own but fails when the whole suite runs. What is the most likely cause?
Globals, module-level caches or database rows left behind by earlier tests change the result. Use fixtures that set up and tear down state, so every test starts clean.
· FreeMistakes that cost offers
- Unit tests that call real third-party APIs.
- Committing secrets to the repository.
- Rewriting shared Git history to undo a commit.
How to practise
Ship like a professional: pytest + mocking, Docker, CI, secrets management, git hygiene and observability.
- Add pytest with fixtures and mocks to a project; reach 70%+ coverage.
- Containerise a service with a cache-friendly Dockerfile and run CI on GitHub Actions.
- Add structured logging with request IDs and an error tracker.
