How to run coverage.py on a directory?

I have a directory tests that includes a lot of different tests named test_*.

I tried to run coverage run tests but it doesn't work.

How can I run a single command to coverage multiple files in the directory?

None of the answers here quite worked for me. I found that coverage and pytest worked fine though:

coverage run -m pytest

This was run at the project folder. It was able to find the folder called tests, and run all the tests (which was split into multiple python files and had a __init__.py file) within them. To see the report run:

coverage report

Here is a complete example with commands from the same PWD for all phases in one place. With a worked up example, I am also including the testing and the report part for before and after coverage is run. I ran the following steps and it worked all fine on osx/mojave.

  1. Discover and run all tests in the test directory

$ python -m unittest discover <directory_name>

Or Discover and run all tests in "directory" with tests having file name pattern *_test.py

$ python -m unittest discover -s <directory> -p '*_test.py'

  1. run coverage for all modules

$ coverage run --source=./test -m unittest discover -s <directory>/

  1. get the coverage report from the same directory - no need to cd.

$ coverage report -m

Notice in above examples that the test directory doesn't have to be named "test" and same goes for the test modules.

You can achieve that using --source. For example: coverage run --source=tests/ <run_tests>

Use --include to only include files in particular directories. It matches file paths, so it can match a subdirectory.
