Show coverage stats online via

Project Description is service to publish your coverage stats online with a lot of nice features. This package provides seamless integration with in your python projects. For ruby projects, there is an official gem. Only projects hosted on Github are supported.

Works with python 2.6+, 3.2+ and pypy 1.9.

Usage (Travis CI)

This library will publish your coverage results on for everyone to see (unless you’re using pro account). This package can possibly work with different CI environments, but it’s only tested to work with Travis CI atm.

  1. First, log in via Github and add your repo on Coveralls website.

  2. Add pip install coveralls to install section of .travis.yml

  3. Make sure you run your tests with coverage during the build in script part. Example:

    # --source specifies what packages to cover, you probably want to use that option
        coverage run --source=yourpackagename test

    Note, that example command will gather coverage for specified package. If you wish to customize what’s included in your reports, consult coverage docs.

  1. Execute run coveralls in after_success section:

      - coveralls

Full example of .travis.yml:

language: python
  - 2.7
  - 3.3
  - pip install -r requirements.txt --use-mirrors
  - pip install coveralls --use-mirrors
  - coverage run --source=moscowdjango,meetup test
  - coveralls

Usage (another CI)

If you’re NOT using Travis, you have to provide at least a repo_token option in .coveralls.yml at the root of your repo. This is your own secret token, which is available at the bottom of your repository’s page on Coveralls. Make sure it stays secret, do not put it in your public repo.

Example of .coveralls.yml:

# .coveralls.yml
repo_token: TjkDuVpGjuQcRhNW8dots9c8SSnv7ReM5

How it works

It makes custom report for data generated by package and sends it to json API of service. All python files in your coverage analysis are posted to this service along with coverage stats, so please make sure you’re not ruining your own security! For private projects there is Coveralls Pro.

Tips for coverage.rc config

This section is a list of most common options for, which collects all the data. Coveralls feeds from this data, so it’s good to know how to to configure it.

To limit the report with only your packages, specify their names (or directores):

source = coveralls,your_otherpackage

To exclude parts of your source from coverage, for example migrations folders:

omit = */migrations/*

Some lines are never executed in your tests, but that can be ok. To mark those lines use inline comments right in your source code:

if debug:   # pragma: no cover
  msg = "blah blah"
  log_message(msg, a)

Sometimes it can be tedious to mark them in code, so you can specify whole lines to .coveragerc:

exclude_lines =
    pragma: no cover
    def __repr__
    raise AssertionError
    raise NotImplementedError
    if __name__ == .__main__.:


Run tests:

$ python test

Install latest unstable version:

$ pip install coveralls==dev
