leverage tox to facilitate the development

Before submitting a patch, we need to execute flake8, unittest,
open coverage report, now with the help of tox any pytest,
we can process them all with only one command.

pytest is choosen here is because of its useful assert showcase,
and powerful properties and healthy ecosystem(plugins of mock etc)
