Have you ever experienced this pain: your project needs to run on Python 3.9, 3.10, 3.13, and PyPy, installing dependencies over and over again, and then you have to remember commands, write scripts, and modify CI configurations...
It's heartbreaking to talk about - after all that hassle, you still easily miss some version. How great it would be if you could run everything with one click!
What is tox
Simply put, tox is a "universal testing platform" —
It automatically creates new virtual environments for each test environment;
Installs dependencies, runs tests, does formatting, publishes packages... according to configuration
Integrates with CI, no more writing repetitive scripts across various platforms.
To put it simply, tox is like a smart chef in your home - ingredients (dependencies) are prepared, recipes (commands) are set, executed in order, and finally served on the table, perfectly executed.
