Cannot run tests with pytest anymore

[andreagrandi]

Hi everyone,

I was going to work on CircleCI (and this is a confirmation that I probably should have done it sooner) integration, and before doing that I wanted to make sure that pytest was still running correctly, but despite having installed all the required libraries in my virtual environment, I'm getting this error:

(covid-api) ➜  covid-api git:(master) ✗ pytest

Hint: make sure your test modules/packages have valid Python names.
Traceback:

E   ModuleNotFoundError: No module named 'fastapi.testclient'

I've also tried to open a Python shell and import it manually, but I'm getting the same error:

(covid-api) ➜  covid-api git:(master) ✗ python

>>> from fastapi.testclient import TestClient
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'fastapi.testclient'

Does anyone know how/when this was broken? Am I doing something wrong?
