To effectively use Pytest within a Python virtual environment, follow these instructions:
First, create a virtual environment using Python. Assuming you are using the current latest version, (Python 3.12 at the time of writing), you can create the virtual environment with the following command:
python3.12 -m venv venv
Activate the virtual environment with:
source venv/bin/activate
Once the environment is active, install Pytest:
pip install -U pytest
If you have tests in your project directory, you can run Pytest using:
pytest
If you face any issues when running pytest, try executing it with the Python module invocation method:
python -m pytest
