"import pendulum" causes unwanted import of pytest (presence of pytest in sys.modules often used to control Python behaviour)

[tomjridge]

• I am on the latest Pendulum version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• OS version and name: macOS 13.3.1 (a)

• Pendulum version: 3.0.0

Issue

The following code:

python -c "import sys; import pendulum; print('pytest' in sys.modules)"

prints True. Unfortunately the test 'pytest' in sys.modules is often used to detect whether code is running under pytest or not, and modify code behaviour accordingly (see eg https://pypi.org/project/pytest-is-running/)

Ideally importing pendlum would not cause pytest to be imported.

Is this possible to fix easily?

Thanks for the great work on pendulum!

Seems to be caused by the pypi package "time-machine"
