### 🤔 What's the problem you're trying to solve?

Most of python project use python virtual environment.
It would be possible to select winch the cucumber plugin should use for running the scenario.

### ✨ What's your proposed solution?

A eclipse pydev project already have this feature, in fact in our project we choose to use out test virtual environment with the right version of python, pyton libraries and behave.

The virtual env is in fact a folder in with a real python environment is installed.
