# This file is a pytest root configuration file and provide the following functionalities:
# 1. Defines a few fixtures that could be used under the whole project.
# 2. Defines a few hook functions.
#
# IDF is using [pytest](https://github.com/pytest-dev/pytest) and
# [pytest-embedded plugin](https://github.com/espressif/pytest-embedded) as its example test framework.
#
# This is an experimental feature, and if you found any bug or have any question, please report to
# https://github.com/espressif/pytest-embedded/issues
