preventing python coverage from including virtual environment site packages

Question

I am new to coverage and ran into a strange problem. My coverage is taking my virtual environment site packages into account. Here is the output of the coverage run:

<         


        

Answer 1

Thanks to tknickman I figured it out: Use either

coverage run --source  test.py

or create a configuration file .coveragerc which resides in the directory you run coverage from, with the following content:

[run]
source =
    

This provides you do not have your virtual environment installed under the project directory. If you have the virtual environment installed under the project dir you can use

coverage run --source  --omit  test.py

Note that omit wants a file pattern like

~/projectdir/venv/*

instead of a path.

The corresponding .coveragerc would look like this:

[run]
source=
    
omit=
    //*

I still think that like packages of the standard library any packages installed under site-packages should not be covered by default.
