Migrate to pytest

[Glandos]

Currently, we are using pytest for launching tests, but they are all written with Flask-Testing and unittest.

Since Flask-Testing is nearly dead, and Flask is moving fastly, we should move away from it, and use another way to write test. As far as I can tell, the base documentation for testing Flask can easily use fixtures of pytest.

In this issue, I want to discuss what we are currently using, and what could be done to move to pytest.

However, there might be other library I'm not aware of.

flask_testing.TestCase

• Could be replaced by a fixture to create the app, as before.
• Creating the database seems to be left as an exercise for the user.
