Technical requirements

We need a working Python interpreter along with Tox. Tox can be installed with the following command:

$ pip install tox

Even though we are going to use the same test suite and contacts app we wrote in Chapter 8, PyTest Essential Plugins, we only need to install Tox 3.20.0. All other dependencies will be managed by Tox for us.
