Add parameterized to requirements.txt (or to test-requirements.txt)

[ancieg]

When I run python3 -m unittest (after installing dependencies listed in requirements.txt), I encounter the following errors:

I think that is a good idea to add parameterized to requirements.txt (or to test-requirements.txt).
