The project is using Travis-CI service for continous integration and testing.
Current build status is:
If you are submitting a patch or pull request please make sure it does not break the build.
There’s also a config file for running tests with Tox (pip install tox):
tox
It is not however very convenient at the moment because Tox recreates the test environment (which is a good thing) and builds numpy from source on every run (which takes a lot of time).
