| 3 | Continuous Integration testing |
| 4 | ============================== |
| 5 | |
| 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. |
| 11 | |
| 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. |
| 17 | |
| 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. |
| 22 | |
| 23 | Azure Pipelines |
| 24 | --------------- |
| 25 | |
| 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. |
| 28 | |
| 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 |
| 32 | description. |
| 33 | |
| 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. |
| 39 | |
| 40 | GitLab CI Pipelines |
| 41 | ------------------- |
| 42 | |
| 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. |
| 52 | |
| 53 | Docker container |
| 54 | ---------------- |
| 55 | |
| 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. |
| 61 | |
| 62 | Customizing CI |
| 63 | -------------- |
| 64 | |
| 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 |
| 70 | prior to submission. |
