Current behavior

Every testing module is inside the 'tests' folder.

New behavior

Inside a newly created folder called 'unit', testing modules which contained only tests classified as unit tests were brought inside the unit folder. There are nine modules inside the 'unit' folder, and all of them should contain only unit tests. This is the beginning of the procedure described in #480. Every testing module outside this 'unit' folder contains only tests which are not unit tests. The test_tank.py was not further analyzed because it needs to be worked on more carefully later.

I think I finally understand this PR after the discussions we had yesterday.

I have nothing against the new tst/testing-suite-reestructuring file.

However, what is the difference between this new file and the currently https://github.com/RocketPy-Team/RocketPy/blob/develop/tests/test_function.py file? I was under the impression you were creating new code but I think you simply copy and past code.

Seems like you duplicated a file. The tests in the tests/test_function.py still exist so you're testing the same thing twice. If that's true, you should use git mv command to move one file to another folder. In that case I suggest you to delete the branch and start this work again.

Actually, what was classified as an unit test was kept inside the test_function.py module inside the folder 'unit'. What was not an unit test remained intact in the original test_function.py file.

Thanks a lot to @Gui-FernandesBR which greatly contributed this work.

Looks great to me, Great work @lucasfourier !!

In the future we want to run unit tests before integration tests when triggering the github actions, this will save us some time.

Next step is defining the integration tests schema, I"m still not sure how to do or where to save them.
