Is it possible exclude test directories from coverage.py reports?

Question

I'm kind of a rookie with python unit testing, and particularly coverage.py. Is it desirable to have coverage reports include the coverage of your actual test files?

Here's a screenshot of my HTML report as an example.

You can see that the report includes tests/test_credit_card. At first I was trying to omit the tests/ directory from the reports, like so:

coverage html --omit=tests/ -d tests/coverage

I tried several variations of that command but I could not for the life of me get the tests/ excluded. After accepting defeat, I began to wonder if maybe the test files are supposed to be included in the report.

Can anyone shed some light on this?

Answer 1

coverage html --omit="*/test*" -d tests/coverage

Answer 2

Create .coveragerc file in your project root folder, and include the following:

[run]
omit = *tests*

Answer 3

You can also explicitly specify which directory has the code you want coverage on instead of saying which things to omit. In a .coveragerc file, if the directory of interest is called demo, this looks like

[run]
source = demo
