You've used pytest and you've used mypy, but bugs are still slipping through your code. What's next? In this talk, we cover two simple but powerful tools for keeping your code problem-free. Property-based testing, provided by the […

Во время лекции поговорим о том, что такое тестирование ПО, какие бывают тесты и зачем их писать. Расскажем про библиотеки для тестирования Python-кода: unittest, pytest, doctest. Узнаем, чем они отличаются, и посмотрим на простые примеры тестов. Затронем…

Speaker: Justin Crown

Many of us practice test driven development, and pride ourselves in our code coverage. This is relatively easy to do when you begin a new project, but what happens when you take over an existing code base with little to no tests? Where…
