How can I effectively test my Python library?

You can use frameworks like unittest or pytest to write and run your tests. Do you need help with a specific framework?

I'm more familiar with pytest. Can you give me an example?

Sure! Here's a simple example:

import pytest

def add(a, b):
    return a + b


def test_add():
    assert add(1, 2) == 3
    assert add(-1, 1) == 0

This tests the add function. Would you like to know more about test organization?

Yes, how should I organize my tests?

It's common to create a tests directory at the root of your project. Inside, you can have separate files for different modules. For example, if you have a module named math_utils.py, you could create a file named test_math_utils.py for its tests.

That makes sense! How do I run the tests?

You can run your tests using the command pytest in your terminal. It will automatically discover and run all the tests in your tests directory.
