Pytest is a powerful testing framework for Python that simplifies the process of writing and running tests. It is designed to make building simple and scalable tests easy, allowing developers to focus on writing effective tests without the need for boilerplate code. One of the key advantages of pytest is its readability; tests are easy to write and understand, which enhances collaboration among team members ².

To get started with pytest, you need to follow certain naming conventions. Test files should be named either test_<something>.py or <something>_test.py, and test functions should start with the prefix test_. This ensures that pytest recognizes them as test cases ⁵.

Installation is straightforward; you can install pytest using the command pip install pytest. Once installed, you can run tests by executing the command pytest in your terminal, which will automatically discover and run all the tests in the current directory and its subdirectories ²⁵.

Overall, pytest is an excellent choice for both beginners and experienced developers looking to implement effective testing practices in their Python projects.
