Introduction to Pytest

Pytest is a Python-based testing framework for writing and executing test code. In today’s REST services, pytest is primarily used for API testing, although we can use pytest to write both simple and complex tests, meaning we can write code to test APIs, databases, UIs, and more.

Advantages of Pytest

The advantages of Pytest are as follows:

• Pytest can run multiple tests in parallel, reducing the execution time of your test suite.

• If not explicitly mentioned, Pytest has its own way of automatically detecting test files and test functions.

• Pytest allows us to skip a subset of tests during execution.

• Pytest allows us to run a subset of our entire test suite.

• Pytest is free and open source.

• Due to its simple syntax, pytest is very easy to get started with.

In this tutorial, we will explain the basics of pytest using example programs.
