pytest: Simple, rapid and fun testing with Python

Setup instructions

• We'll be using pytest on the commandline for the training.
• If you use PyCharm:
  • Open the code/ folder as a project
  • Open basic/test_calc.py, configure Python interpreter
  • Wait until "Install requirements" prompt appears and accept
  • Open a terminal inside PyCharm
• If you use VS Code:
  • Open the code/ folder as a project
  • Ctrl-Shift-P to open command palette, run "Python: Create Environment..."
  • Select venv and requirements.txt for installation
  • Click beaker icon in the sidebar, you should see a tree of tests (some will fail when running them)
  • Open a terminal inside VS Code
• Manual setup:
  • Create a virtualenv and activate it (or substitute tool paths below)
  • pip install -r code/requirements.txt
• Check everything works:
  • Check python3 --version (Windows: py -3 --version), make sure you run 3.8 or newer.
  • Check pytest --version, you should see 8.4.x ideally (7.0+ is ok)
• In case of trouble/questions, please feel free to ask! Any of these will work fine:
  • florian@bruhin.software
  • IRC: The-Compiler on Libera Chat
  • @the_compiler on Discord (e.g. Python Discord or EuroPython Discord)

Preparation

If you want to prepare, take a look at rpncalc/ (especially rpn_v2.py and utils.py), which is a small example project we'll use in the training.
