Coverage.py seems to missing something

[rahul-gj]

I am on windows 10
The environment is miniconda as in the django-crash-course book.

After running the coverage run -m pytest

Results (1.74s):
       9 passed

after running coverage report

No data to report.

That is inconsistent with what is in the book.

I smelled something fishy. I then opened .coveragerc

[run]
include = everycheese/*
omit = *migrations*, *tests*
plugins =
    django_coverage_plugin

That seems ok.

for testing, I just deleted the file.

running above codes after deleting .coveragerc file gave.

Not what exactly in the book but acceptable compared to no data to report

Am I missing something, or this is due to buggy windows as always?
