--cov don't include recursively folders and files

Summary

Expected vs actual result

I want to integrate all the python files in from my src folder only, even the untested ones.

I managed to get the expected result by indicating all the folders of my project (see Config), but it is not very practical …

I also tried with --cov or --cov . but I get the same result.

Actual

This is a limitation of coverage.py - as soon as it discovers a directory without an __init__.py file, it stops recursing (from your example, you do not seem to have any __init__.py files). See coverage.files.find_python_files (https://github.com/nedbat/coveragepy/blob/e1f720afb9ad31c6366f26b6fa71a5943ffa97c1/coverage/files.py#L398) for the implementation. Running this method with your directory will give you the files the collection of uncovered files will consider.

The module structure is still valid, as recent Python versions do not require you to provide (empty) __init__.py files any more for directories to be importable (implicit namespace packages/PEP 420, introduced in Python 3.3).
