Write Unit Tests for OpenCV server

[KjetilIN]

What?

Write unit tests for the OpenCV server. If we do not do it, we need to remove the folder for tests!

Tests could be to detect a single face in a image and see if the model is able to find it without errors.

List of tests that are useful:

• [x] Test models are being loaded
• [x] Test that the files trained models can be found in correct directory
• [ ] Test distance estimation function (with images at different distances)
• [ ] Test that each model can find a single face in a image
• [ ] Test that each model can find two faces in a image

Up for review 16th April

Please read the pr RIT-NTNU-Bachelor/OpenCV_Server#33 It has all the information needed. It should be read through before giving feedback

Test that are not implemented, but should be discussed:

• Test distance estimation function (with images at different distances)
• Test that each model can find a single face in a image
• Test that each model can find two faces in a image

To Do Before Close

Discuss if more tests are required

[KjetilIN]

Doing distance testing and then not sure how much more we should prioritize
