Dear all,
I am following the guide in this article: https://docs.databricks.com/en/notebooks/testing.html
however I am unable to run pytest due to the following error: ImportError while importing test module '/Workspace/Users/deadmanhide@gmail.com/test_trans.py'
and
E ModuleNotFoundError: No module named 'test_trans'
My setup is:
Workspace:
run_tests.py (NoteBook where I install pytest and run pytest.main)
test_trans.py(Python file containing the unit tests)
transform (folder)
-- operations.py(Notebook with transform and cleansing functions)
-- __init__.py
I also tried to put test file and transform file inside the folders with __init__.py file so it would be treated as a package, also tried to do the same in Repos and not on workspace.
Clearly I am doing something wrong, would greatly appreciate any help,
Kind regards

Thank you very much for a detailed answer Kaniz! I have followed the steps you described and decided to simplify the structure further, now I have all 3 files at the same level and now I can collect my 2 tests.
The issue is with the module imports again, I have followed the guide from DataBricks regarding Unit Testing howecver it seems I am still missing something.
In my workspace I have two notebooks (transform_functions and run_tests) and a python file test_trans.py file, all at the same level.
The error I am getting is:
FAILED test_trans.py::test_check_columns_exist - ModuleNotFoundError: No module named 'transform_functions' FAILED test_trans.py::test_transform_replace_nulls - ModuleNotFoundError: No module named 'transform_functions'
def test_check_columns_exist(get_sparksession, get_test_df): > from transform_functions import * E ModuleNotFoundError: No module named 'transform_functions' test_trans.py:36: ModuleNotFoundError
tranform_functions is a notebook at the same level as test_trans.py so I am a bit confused as to why I am getting this error...
Full unit test function code which causes the error:

PS: I have restarted the cluster and ran my run_tests notebook again and now I am getting a different error:
E File "/Workspace/Repos/SBIT/SBIT/test_trans.py", line 36 E from transform_functions import * E ^ E SyntaxError: import * only allowed at module level
I am totally confused now โฆ
