Pytest с нуля: Первые тесты за 2.5 часа
Первый тест за 10 минут. Assert, фикстуры, параметризация — только база для быстрой победы.
What you'll learn
Быстрый старт для абсолютных новичков: напишите первые 10-15 тестов без перегрузки. Assert, фикстуры, параметризация, маркеры — только база, без coverage и xdist. Мгновенная победа за 2.5 часа.
First test in 10 minutes
Install pytest, first assert, run—no complex theory. Instant win for motivation.
Only basics—no overload
No coverage, xdist, API mocks. Only what's needed for first 10-15 tests. Learn without cognitive overload.
AAA pattern and best practices
Arrange-Act-Assert structure from first test. Right habits from the start.
Ready for next step
After course you confidently write basic tests and ready for mocks, coverage, and production tools.
Testimonials
alumni“Test-first programming is not a testing technique, it's a design technique. Tests give you the courage to change code.”
Kent Beck (создатель TDD)
“Imperfect tests, run frequently, are much better than perfect tests that are never written at all.”
Martin Fowler
What's inside
Installing pytest and first test: pip install, assert, pytest -v—running and understanding output
AAA pattern: Arrange-Act-Assert structure for readable tests
Testing exceptions: pytest.raises for error checking
Simple fixtures: @pytest.fixture for data reuse
Parametrization: @pytest.mark.parametrize for multiple scenarios in one test
Markers: @pytest.mark.slow for grouping and filtering tests
Basic debugging: -v, -s, --pdb for understanding failures

FAQ
I've never written tests. Is this for me?
YES! This course is made exactly for absolute beginners. You'll write first test in 10 minutes and by end of course confidently test classes, functions, and exceptions.
Why only 2.5 hours? Is it enough?
This is ONLY basics: assert, fixtures, parametrization. Enough for first 10-15 tests. Mocks, coverage, xdist—in next courses. Focus on quick win without overload.
What's next after this course?
Next step—'Pytest for Juniors: Mocks and Integration' (Level 2). There you'll learn to mock HTTP, files, work with coverage and pytest.ini. Clear learning path.
Is there practice?
Every lesson is practice. You write tests immediately, not watch theory. By end you'll have 10-15 working tests for portfolio.
