How to generate coverage reports
coverage.py is required to collect coverage metrics. Below are some examples on how to include coverage tracking during your tests. Codecov will call
coverage xml -i automatically to generate the coverage xml output, which will be archived and processed server side.
You may need to configure a
.coveragercfile. Learn more here: http://coverage.readthedocs.org/en/latest/config.html. Start with this generic
pip install coverage coverage run tests.py
pip install pytest-cov py.test --cov=./
Codecov can be ran from inside your
tox.ini please make sure you pass all the necessary environment variables through:
[testenv] passenv = CI TRAVIS TRAVIS_* deps = codecov commands = codecov
See all the environment variable for other CI providers here.
Frequently Asked Questions
❔Whats the different between the codecov-bash and codecov-python uploader?
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.
❔Why am I seeing
No data to report.
This output is written by running the command
coverage xml and states that there were no
.coverage files found.
- Make sure coverage is enabled. See Enabling Coverage
- You may need to run
coverage combinebefore running Codecov
- Using Docker? Please follow this step: Testing with Docker: Codecov Inside Docker
❔Can I upload my
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.
