How do I test my Python package effectively?

To test your Python package effectively, you can use frameworks like unittest or pytest. Have you used any testing frameworks before?

I've heard of pytest but haven't used it yet. What are its advantages?

Pytest is user-friendly and supports fixtures, parameterized testing, and plugins, making it powerful for complex testing.

Can you show me a simple example of a pytest test case?

Sure! Here's a basic example:

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

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

You can run this with the command pytest in your terminal.

What should I do if my tests fail?

If your tests fail, check the error messages for clues. Debug your code, and consider adding more tests to cover edge cases.
