I want to write unit tests in my Python project. How can I create a simple test file using Pytest and run the tests I wrote through the terminal? Please tell me about the assert structure I should use when defining test functions and the file naming conventions for automatic discovery of tests.
Repository: https://github.com/pytest-dev/pytest. Follow the official instructions in the README of this repository for setup and execution.
Before starting, check which OS we are on and if the necessary tools (e.g., Python, Node.js, Git, Docker) are installed. Install any missing ones step-by-step according to this system.
Create a new, empty folder to work in. Do not touch any files outside this folder and do not delete anything. Tell me what you are going to do in one sentence before running each command.
Tell me what I should see on the screen at the end of each step. If an error occurs, I will paste the error message to you exactly as it is, and we will fix it together.
