Tests
=====
.. image:: https://coveralls.io/repos/dpkp/kafka-python/badge.svg?branch=master&service=github
:target: https://coveralls.io/github/dpkp/kafka-python?branch=master
.. image:: https://travis-ci.org/dpkp/kafka-python.svg?branch=master
:target: https://travis-ci.org/dpkp/kafka-python
Test environments are managed via tox. The test suite is run via pytest.
Individual tests are written using unittest, pytest, and in some cases,
doctest.
Linting is run via pylint, but is generally skipped on python2.6 and pypy
due to pylint compatibility / performance issues.
For test coverage details, see https://coveralls.io/github/dpkp/kafka-python
The test suite includes unit tests that mock network interfaces, as well as
integration tests that setup and teardown kafka broker (and zookeeper)
fixtures for client / consumer / producer testing.
Unit tests
------------------
To run the tests locally, install tox -- `pip install tox`
See http://tox.readthedocs.org/en/latest/install.html
Then simply run tox, optionally setting the python environment.
If unset, tox will loop through all environments.
.. code:: bash
tox -e py27
tox -e py35
# run protocol tests only
tox -- -v test.test_protocol
# re-run the last failing test, dropping into pdb
tox -e py27 -- --lf --pdb
# see available (pytest) options
tox -e py27 -- --help
Integration tests
-----------------
.. code:: bash
KAFKA_VERSION=0.10.0.1 tox -e py27
KAFKA_VERSION=0.8.2.2 tox -e py35
Integration tests start Kafka and Zookeeper fixtures. This requires downloading
kafka server binaries:
.. code:: bash
./build_integration.sh
By default, this will install 0.8.1.1, 0.8.2.2, 0.9.0.1, and 0.10.0.1 brokers into the
servers/ directory. To install a specific version, set `KAFKA_VERSION=0.9.0.0`:
.. code:: bash
KAFKA_VERSION=0.8.0 ./build_integration.sh
Then run the tests against supported Kafka versions, simply set the `KAFKA_VERSION`
env variable to the server build you want to use for testing:
.. code:: bash
KAFKA_VERSION=0.9.0.1 tox -e py27
To test against the kafka source tree, set KAFKA_VERSION=trunk
[optionally set SCALA_VERSION (defaults to 2.10)]
.. code:: bash
SCALA_VERSION=2.11 KAFKA_VERSION=trunk ./build_integration.sh
KAFKA_VERSION=trunk tox -e py35
