Continuous Integration testing
|
|
==============================
|
|
|
|
All changes require passing our continuous integration tests prior to being
|
|
merged in to mainline. To help facilitate merges being accepted quickly,
|
|
custodians are encouraged but not required to run a pipeline prior to sending a
|
|
pull request. Individual developers submitting significant or widespread
|
|
changes are encouraged to run a pipeline themselves prior to posting.
|
|
|
|
In order to make this process as easy as possible, the ability to run a CI
|
|
pipeline is provided in both Azure and GitLab. Both of these pipelines perform
|
|
their Linux build jobs on the same Docker container image and to cover the same
|
|
platforms. In addition, Azure is also used to confirm that our host tools can
|
|
be built with mingw to run on Windows.
|
|
|
|
Each of the pipelines is written in such as way as to be a "world build" style
|
|
test and as such we try and build all possible platforms. In addition, for all
|
|
platforms that support being run in QEMU we run them in QEMU and use our pytest
|
|
suite. See :doc:`py_testing` for more information about those tests.
|
|
|
|
Azure Pipelines
|
|
---------------
|
|
|
|
This pipeline is defined in the top-level ``.azure-pipelines.yml`` file.
|
|
Currently there are two ways to run a Microsoft Azure Pipeline test for U-Boot.
|
|
|
|
The first way is to create an account with Microsoft at
|
|
https://azure.microsoft.com/en-us/services/devops/ and then use the
|
|
``.azure-pipelines.yml`` file in the U-Boot repository as the pipeline
|
|
description.
|
|
|
|
The second way is to use GitHub. This requires a GitHub account
|
|
and to fork the repository at https://github.com/u-boot/u-boot and to then
|
|
submit a pull request as this will trigger an Azure pipeline run. Clicking on
|
|
your pull request on the list at https://github.com/u-boot/u-boot/pulls and
|
|
then the "Checks" tab will show the results.
|
|
|
|
GitLab CI Pipelines
|
|
-------------------
|
|
|
|
This pipeline is defined in the top-level ``.gitlab-ci.yml`` file. Currently,
|
|
we support running GitLab CI pipelines only for custodians, due to the
|
|
resources the project has available. For Custodians, it is a matter of
|
|
enabling the pipeline feature in your project repository following the standard
|
|
GitLab documentation. For non-custodians, the pipeline itself is part of the
|
|
tree and should be able to be used on any GitLab instance, with whatever
|
|
runners you are able to provide. While it is intended to be able to run this
|
|
pipeline on the free public instances provided at https://gitlab.com/ a problem
|
|
with our squashfs tests currently prevents this.
|
|
|
|
Docker container
|
|
----------------
|
|
|
|
As previously stated, both of the above pipelines build using the same Docker
|
|
container image. This is maintained in the U-Boot source tree at
|
|
``tools/docker/Dockerfile`` and new images are made as needed to support new
|
|
tests or features. This file needs to be updated whenever adding new external
|
|
tool requirements to tests.
|
|
|
|
Customizing CI
|
|
--------------
|
|
|
|
As noted above, the CI pipelines perform a world build. While this is good for
|
|
overall project testing, it can be less useful for testing specific cases or
|
|
developing features. In that case, it can be useful as part of your own
|
|
testing cycle to edit these pipelines in separate local commits to pair them
|
|
down to just the jobs you're interested in. These changes must be removed
|
|
prior to submission.
