3 Continuous Integration testing
4 ==============================
6 All changes require passing our continuous integration tests prior to being
7 merged in to mainline. To help facilitate merges being accepted quickly,
8 custodians are encouraged but not required to run a pipeline prior to sending a
9 pull request. Individual developers submitting significant or widespread
10 changes are encouraged to run a pipeline themselves prior to posting.
12 In order to make this process as easy as possible, the ability to run a CI
13 pipeline is provided in both Azure and GitLab. Both of these pipelines perform
14 their Linux build jobs on the same Docker container image and to cover the same
15 platforms. In addition, Azure is also used to confirm that our host tools can
16 be built with mingw to run on Windows.
18 Each of the pipelines is written in such as way as to be a "world build" style
19 test and as such we try and build all possible platforms. In addition, for all
20 platforms that support being run in QEMU we run them in QEMU and use our pytest
21 suite. See :doc:`py_testing` for more information about those tests.
26 This pipeline is defined in the top-level ``.azure-pipelines.yml`` file.
27 Currently there are two ways to run a Microsoft Azure Pipeline test for U-Boot.
29 The first way is to create an account with Microsoft at
30 https://azure.microsoft.com/en-us/services/devops/ and then use the
31 ``.azure-pipelines.yml`` file in the U-Boot repository as the pipeline
34 The second way is to use GitHub. This requires a GitHub account
35 and to fork the repository at https://github.com/u-boot/u-boot and to then
36 submit a pull request as this will trigger an Azure pipeline run. Clicking on
37 your pull request on the list at https://github.com/u-boot/u-boot/pulls and
38 then the "Checks" tab will show the results.
43 This pipeline is defined in the top-level ``.gitlab-ci.yml`` file. Currently,
44 we support running GitLab CI pipelines only for custodians, due to the
45 resources the project has available. For Custodians, it is a matter of
46 enabling the pipeline feature in your project repository following the standard
47 GitLab documentation. For non-custodians, the pipeline itself is part of the
48 tree and should be able to be used on any GitLab instance, with whatever
49 runners you are able to provide. While it is intended to be able to run this
50 pipeline on the free public instances provided at https://gitlab.com/ a problem
51 with our squashfs tests currently prevents this.
56 As previously stated, both of the above pipelines build using the same Docker
57 container image. This is maintained in the U-Boot source tree at
58 ``tools/docker/Dockerfile`` and new images are made as needed to support new
59 tests or features. This file needs to be updated whenever adding new external
60 tool requirements to tests.
65 As noted above, the CI pipelines perform a world build. While this is good for
66 overall project testing, it can be less useful for testing specific cases or
67 developing features. In that case, it can be useful as part of your own
68 testing cycle to edit these pipelines in separate local commits to pair them
69 down to just the jobs you're interested in. These changes must be removed
