Python ModuleNotFoundError. Probably a simple mistake - python-3.x

Question

I am trying to setup up some test cases using pytest for a project i'm working on and have setup my directory like so.
C:.
│ OpenGLTestCase.py
│ Sprite.py
│ SpriteManager.py
│ SpriteRenderer.py
│ Texture.py
│ __init__.py

The parent folder that holds all of this is called "pygameOpenGLUtil". I have my main 4 files in the highest directory along with my __init__.py. When I try and run pytest at this level it says throws a "ModuleNotFoundError: No module named 'pygameOpenGLUtil'". This thrown in my test_sprite_manager.py file. I've gotten this to work in other projects before but I can't seem to figure out what is wrong with this one I am sure i'm just forgetting something small.
Here is my __init__.py:
from .OpenGLTestCase import *
from .Sprite import *
from .SpriteManager import *
from .SpriteRenderer import *
from .Texture import *
And here is my test_sprite_manager.py:
import pygame
from OpenGL.GL import *
from pygameOpenGLUtil import *
class SpriteManagerTest(OpenGLTestCase):
def test_add_sprite(self):
test_sprite_map = SpriteManager()
test_sprite_one = Sprite(test_sprite_map)
test_sprite_one = Sprite(test_sprite_map)
if __name__ == "__main__":
unittest.main()
I am running python3.7.3 and pytest version 5.0.0
