Continuous integration is part of our development process and ensure that every piece of code or documentation which is contributed to SciPy is working and does not have unforeseen effects.
We run more than 20 different workflows with different versions of the dependencies, different architectures, etc. A PR must pass all these checks before it can be merged as to ensure a sustainable state of the project.
Apart from the unit tests, the documentation and examples in the docstrings are also checked. These are common failing workflows as Sphinx and doctests have very strict rules. These aspects are very important as documentation and examples are user facing elements. Ensures that these elements are properly rendered.
The logs can be long, but you will always find out why your build/test did not
pass a check. Simply click on

Following is a list of all the different workflows in use. They are grouped by CI resources providers.
Windows Tests: test suite runs for Windows (
Linux Tests: test suite runs for Linux (
macOS Tests: test suite runs for macOS (
Test suite runs on GitHub Actions and other platforms cover a range of
test/environment conditions: Python and NumPy versions
(lowest-supported to nightly builds), 32-bit vs. 64-bit, different compilers,
and more - for details, see the
.yml configuration files.
Lint: PEP8 and code style
Windows Python: test suite runs for Windows
Linux_Python_xx_32bit_full: 32-bit Linux
wheel_optimized_gcc: install the wheel, then run the test suite with python -OO
source_distribution: install via
sdist, then run the test suite
refguide_asv_check: doctests from examples and benchmarks
prerelease_deps_coverage_64bit_blas: use pre-released version of the dependencies and check coverage
build_docs: build the documentation
build_docs artifact: live preview of the documentation
run_benchmarks: verify how the changes impact performance
patch: the impact on code coverage due to your changes
project: the coverage of the whole project
Being an open-source project, we have access to a quota of CI resources. Ultimately, resources are limited and we should use them with care. This is why we ask you to verify your changes locally before pushing them.
Depending on the proposed change, you might want to skip part of the checks. It will be at the discretion of a maintainer to re-run some tests before integration.
Skipping CI can be achieved by adding a special text in the commit message:
[skip azp]: will skip Azure
[skip actions]: will skip GitHub Actions
[skip circle]: will skip CircleCI
[skip ci]: will skip all CI
Of course, you can combine these to skip multiple workflows.
This skip information should be placed on a new line. In this example, we
just updated a
.rst file in the documentation and ask to skip Azure and
GitHub Actions’ workflows:
DOC: improve QMCEngine examples. [skip azp] [skip actions]
