pytest vs unittest : What are the differences?
Developers describe pytest as "A full-featured Python testing tool to help you write better programs". A framework makes it easy to write small tests, yet scales to support complex functional testing for applications and libraries. It is a mature full-featured Python testing tool. On the other hand, *unittest * is detailed as "A unit testing framework for Python". It is python’s xUnit style framework. It works much the same as the other styles of xUnit, and if you’re familiar with unit testing in other languages, this framework (or derived versions), may be the most comfortable for you.
pytest and unittest can be primarily classified as "Testing Frameworks" tools.
pytest is an open source tool with 4.62K GitHub stars and 1.11K GitHub forks. Here's a link to pytest's open source repository on GitHub.
