What is pytest and how do I use it?

Pytest is a testing framework for Python that makes it easy to write simple and scalable test cases. You can use it to test your code by writing functions that assert expected outcomes.

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

Sure! Here's a simple example:

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

This tests a function add to ensure it returns the correct sum.

How do I run my tests using pytest?

You can run your tests by navigating to your project directory in the terminal and executing the command pytest. It will automatically discover and run all the test files.

What if I want to see more detailed output when running tests?

You can use the -v option for verbose output. Just run pytest -v to see more details about each test.
