It is mainly used to write API test cases. pytest has some other great features: Support for the built-in assert statement instead of using special self.assert*() methods; Pytest is a testing framework based on python.

Tavern is a pytest plugin, command-line tool and Python library for automated testing of APIs, with a simple, concise and flexible YAML-based syntax. Then “pytest” runs all the tests with mocks (runs fast, tests logical correctness with tight feedback) and “pytest -c integration-tests.ini” runs all tests or runs the subset requiring real third party resource access.
