### Produce Coverage Reports
`coverage.py <https://bitbucket.org/ned/coveragepy>`_ is required to collect coverage metrics.
[coverage.py](https://github.com/nedbat/coveragepy) is required to collect coverage metrics.

Below are some examples on how to include coverage tracking during your tests. Codecov will call `coveragexml -i` automatically to generate the coverage xml output, which will be archived and processed server side.

You may need to configure a ``.coveragerc`` file. Learn more `here <http://coverage.readthedocs.org/en/latest/config.html>`_. Start with this `generic .coveragerc <https://gist.github.com/codecov-io/bf15bde2c7db1a011b6e>`_ for example.

We highly suggest adding `source` to your ``.coveragerc`` which solves a number of issues collecting coverage.

### FAQ
- Q: What's the difference between the codecov-bash and codecov-python uploader?<br/>A: As far as python is concerned, *nothing*. You may choose to use either uploader. Codecov recommends **using the bash uploader when possible** as it supports more unique repository setups. Learn more at `codecov/codecov-bash <https://github.com/codecov/codecov-bash>`_ and `codecov/codecov-python <https://github.com/codecov/codecov-python>`_.
- Q: Why am I seeing `No data to report`?<br/>A: This output is written by running the command ``coverage xml`` and states that there were no ``.coverage`` files found.

1. Make sure coverage is enabled. See Enabling Coverage
2. You may need to run `coverage combine` before running Codecov.
3. Using Docker? Please follow this step: `Testing with Docker: Codecov Inside Docker <https://github.com/codecov/support/wiki/Testing-with-Docker#codecov-inside-docker>`_.
- Q: Can I upload my ``.coverage`` files?<br/> A: **No**, these files contain coverage data but are not properly mapped back to the source code. We rely on ``coveragepy`` to handle this by calling ``coverage xml`` in the uploader.
