Following steps included in the tutorial

Create virtual enviroment

I've followed instruction given in https://stackoverflow.com/questions/54106071/how-can-i-set-up-a-virtual-environment-for-python-in-visual-studio-code  - comment 8

Before launch VSC, activate virtual enviroment.


Open any py file, like acli.py, and choose a python env with 3.7 or equal version
    It's important in order to get the plugin emerging message so you could set new env
    If it doesn't work, try to delete the virtual enviroment folder, and repeat all the steps

python3 -m venv .venv  
source .venv/bin/activate
pip install --upgrade pip
pip install antlr4-python3-runtime
pip install sqlalchemy
pip install pymysql
pip install pytest

App instalation pip install -e .

Execution: pytest or: python -m pytest or: pytest -vvv # verbose
