Documentation
|

-------------
|

If you are contributing to the documentation, please follow the instructions described in the
|

`documentation guidelines <guides/docs_contributing>`_ to properly format and test your changes.
|
||||
|
||||
Testing and CI
|
||||
--------------
|
||||
|
||||
After you have made your changes, you should test them. You can do this in different ways depending on the type of change you have made.
|
||||
|
||||
Examples
|
||||
********
|
||||
|
||||
The easiest way to test an example is to load it into the Arduino IDE and run it on your board. If you have multiple boards,
|
||||
you should test it on all of them to ensure that the example works on all supported targets.
|
||||
|
||||
You can refer to the `Example Contribution Guideline`_ section for more information on how to write and test examples.
|
||||
|
||||
Library Changes
|
||||
***************
|
||||
|
||||
If you have made changes to a library, you should test it on all supported targets. You can do this by loading the library examples (or creating new ones)
|
||||
into the Arduino IDE and running them on your board. If you have multiple boards, you should test it on all of them to ensure that the library
|
||||
works as expected on all targets.
|
||||
|
||||
You can also add a new test suite to automatically check the library. You can refer to the `Adding a New Test Suite`_ section for more information.
|
||||
|
||||
Core Changes
|
||||
************
|
||||
|
||||
If you have made changes to the core, it is important to ensure that the changes do not break the existing functionality. You can do this by running the
|
||||
tests on all supported targets. You can refer to the `Runtime Tests`_ section for more information.
|
||||
|
||||
CI
|
||||
**
|
||||
|
||||
In our repository, we have a Continuous Integration (CI) system that runs tests and fixes on every Pull Request. This system will run the tests
|
||||
on all supported targets and check if everything is working as expected.
|
||||
|
||||
We have many types of tests and checks, including:
|
||||
|
||||
* Compilation tests;
|
||||
* Runtime tests;
|
||||
* Documentation checks;
|
||||
* Code style checks;
|
||||
* And more.
|
||||
|
||||
Let's go deeper into each type of test in the CI system:
|
||||
|
||||
Compilation Tests
|
||||
^^^^^^^^^^^^^^^^^
|
||||
|
||||
The compilation tests are the first type of tests in the CI system. They check if the code compiles on all supported targets.
|
||||
If the code does not compile, the CI system will fail the test and the Pull Request will not be merged.
|
||||
This is important to ensure that the code is compatible with all supported targets and no broken code is merged.
|
||||
|
||||
It will go through all the sketches in the repository and check if they compile on all supported targets. This process is automated and controlled
|
||||
by GitHub Actions. The CI system will run the ``arduino-cli`` tool to compile the sketches on all supported targets.
|
||||
|
||||
Testing it locally using the CI scripts would be too time consuming, so we recommend running the tests locally using the Arduino IDE with
|
||||
a sketch that uses the changes you made (you can also add the sketch as an example if your change is not covered by the existing ones).
|
||||
Make sure to set ``Compiler Warnings`` to ``All`` in the Arduino IDE to catch any potential issues.
|
||||
|
||||
Runtime Tests
|
||||
^^^^^^^^^^^^^
|
||||
|
||||
Another type of test is the runtime tests. They check if the code runs and behaves as expected on all supported targets. If the
|
||||
code does not run as expected, the CI system will fail the test and the Pull Request will not be merged. This is important to ensure that the code
|
||||
works as expected on all supported targets and no unintended crashes or bugs are introduced.
|
||||
|
||||
These tests are specialized sketches that run on the target board and check if the code behaves as expected. This process is automated and
|
||||
controlled by the ``pytest_embedded`` tool. You can read more about this tool in its
|
||||
`documentation <https://docs.espressif.com/projects/pytest-embedded/en/latest/>`_.
|
||||
|
||||
The tests are divided into two categories inside the ``tests`` folder:
|
||||
|
||||
* ``validation``: These tests are used to validate the behavior of the Arduino core and libraries. They are used to check if the core and libraries
|
||||
are working as expected;
|
||||
* ``performance``: These tests are used to check the performance of the Arduino core and libraries. They are used to check if the changes made
|
||||
to the core and libraries have any big impact on the performance. These tests usually run for a longer time than the validation tests and include
|
||||
common benchmark tools like `CoreMark <https://github.com/eembc/coremark>`_.
|
||||
|
||||
To run the runtime tests locally, first install the required dependencies by running:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
pip install -U -r tests/requirements.txt
|
||||
|
||||
Before running the test, we need to build it by running:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
./.github/scripts/tests_build.sh -s <test_name> -t <target>
|
||||
|
||||
The ``<test_name>`` is the name of the test you want to run (you can check the available tests in the ``tests/validation`` and
|
||||
``tests/performance`` folders), and the ``<target>`` is the target board you want to run the test on. For example, to run the ``uart`` test on the
|
||||
ESP32-C3 target, you would run:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
./.github/scripts/tests_build.sh -s uart -t esp32c3
|
||||
|
||||
You should see the output of the build process and the test binary should be generated in the ``~/.arduino/tests/<test_name>/build.tmp`` folder.
|
||||
|
||||
Now that the test is built, you can run it in the target board. Connect the target board to your computer and run:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
./.github/scripts/tests_run.sh -s <test_name> -t <target>
|
||||
|
||||
For example, to run the ``uart`` test on the ESP32-C3 target, you would run:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
./.github/scripts/tests_run.sh -s uart -t esp32c3
|
||||
|
||||
The test will run on the target board and you should see the output of the test in the terminal:
|
||||
|
||||
.. code-block:: bash

||||

||||

After the test is finished, you can check the output in the terminal and the generated XML file in the test folder.
|
||||
Additionally, for performance tests, you can check the generated JSON file in the same folder.
|
||||
|
||||
You can also run the tests in `Wokwi <https://docs.wokwi.com/>`_ or `Espressif's QEMU <https://github.com/espressif/esp-toolchain-docs/tree/main/qemu>`_
|
||||
by using the ``-W <timeout_in_ms>`` and ``-Q`` flags respectively. You will need to have the Wokwi and/or QEMU installed in your system
|
||||
and set the ``WOKWI_CLI_TOKEN`` and/or ``QEMU_PATH`` environment variables. The ``WOKWI_CLI_TOKEN`` is the CI token that can be obtained from the
|
||||
`Wokwi website <https://wokwi.com/dashboard/ci>`_ and the ``QEMU_PATH`` is the path to the QEMU binary.
|
||||
|
||||
For example, to run the ``uart`` test using Wokwi, you would run:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
WOKWI_CLI_TOKEN=<your_wokwi_token> ./.github/scripts/tests_run.sh -s uart -t esp32c3 -W <timeout_in_ms>
|
||||
|
||||
And to run the ``uart`` test using QEMU, you would run:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
QEMU_PATH=<path_to_qemu_binary> ./.github/scripts/tests_run.sh -s uart -t esp32c3 -Q
|
||||
|
||||
.. note::
|
||||
|
||||
Not all tests are supported by Wokwi and QEMU. QEMU is only supported for ESP32 and ESP32-C3 targets.
|
||||
Wokwi support depends on the `currently implemented peripherals <https://docs.wokwi.com/guides/esp32#simulation-features>`_.
|
||||
|
||||
Adding a New Test Suite
|
||||
#######################
|
||||
|
||||
If you want to add a new test suite, you can create a new folder inside ``tests/validation`` or ``tests/performance`` with the name of the test suite.
|
||||
You can use the ``hello_world`` test suite as a starting point and the other test suites as a reference.
|
||||
|
||||
A test suite contains the following files:
|
||||
|
||||
* ``test_<test_name>.py``: The test file that contains the test cases. Required.
|
||||
* ``<test_name>.ino``: The sketch that will be tested. Required.
|
||||
* ``ci.json``: The file that specifies how the test suite will be run in the CI system. Optional.
|
||||
* ``diagram.<target>.json``: The diagram file that specifies the connections between the components in Wokwi. Optional.
|
||||
* ``scenario.yaml``: The scenario file that specifies how Wokwi will interact with the components. Optional.
|
||||
* Any other files that are needed for the test suite.
|
||||
|
||||
You can read more about the test python API in the `pytest-embedded documentation <https://docs.espressif.com/projects/pytest-embedded/en/latest/usages/expecting.html>`_.
|
||||
For more information about the Unity testing framework, you can check the `Unity documentation <https://github.com/ThrowTheSwitch/Unity>`_.
|
||||
|
||||
After creating the test suite, make sure to test it locally and run it in the CI system to ensure that it works as expected.
|
||||
|
||||
CI JSON File
|
||||
############
|
||||
|
||||
The ``ci.json`` file is used to specify how the test suite and sketches will handled by the CI system. It can contain the following fields:
|
||||
|
||||
* ``targets``: A dictionary that specifies the supported targets. The key is the target name and the value is a boolean that specifies if the
|
||||
target is supported. By default, all targets are assumed to be supported. This field is also valid for examples.
|
||||
* ``platforms``: A dictionary that specifies the supported platforms. The key is the platform name and the value is a boolean that specifies if
|
||||
the platform is supported. By default, all platforms are assumed to be supported.
|
||||
* ``extra_tags``: A list of extra tags that the runner will require when running the test suite in hardware. By default, no extra tags are required.
|
||||
* ``fqbn``: A dictionary that specifies the FQBNs that will be used to compile the sketch. The key is the target name and the value is a list
|
||||
of FQBNs. The `default FQBNs <https://github.com/espressif/arduino-esp32/blob/a31a5fca1739993173caba995f7785b8eed6b30e/.github/scripts/sketch_utils.sh#L86-L91>`_
|
||||
are used if this field is not specified.
|
||||
|
||||
The ``wifi`` test suite is a good example of how to use the ``ci.json`` file:
|
||||
|
||||
.. literalinclude:: ../../tests/validation/wifi/ci.json
|
||||
:language: json
|
||||
|
||||
Documentation Checks
|
||||
^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The CI also checks the documentation for any compilation errors. This is important to ensure that the documentation layout is not broken.
|
||||
To build the documentation locally, please refer to the `documentation guidelines <guides/docs_contributing>`_.
|
||||
|
||||
Code Style Checks
|
||||
^^^^^^^^^^^^^^^^^
|
||||
|
||||
For checking the code style and other code quality checks, we use pre-commit hooks.
|
||||
These hooks will be automatically run by the CI when a Pull Request is marked as ``Status: Pending Merge``.
|
||||
You can check which hooks are being run in the ``.pre-commit-config.yaml`` file.
|
||||
|
||||
You can read more about the pre-commit hooks in the `pre-commit documentation <https://pre-commit.com/>`_.
|
||||
|
||||
If you want to run the pre-commit hooks locally, you first need to install the required dependencies by running:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
pip install -U -r tools/pre-commit/requirements.txt
|
||||
|
||||
Then, you can run the pre-commit hooks staging your changes and running:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
pre-commit run
|
||||
|
||||
To run a specific hook, you can use the hook name as an argument. For example, to run the ``codespell`` hook, you would run:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
pre-commit run codespell
|
||||
|
||||
If you want to run the pre-commit hooks automatically against the changed files on every ``git commit``,
|
||||
you can install the pre-commit hooks by running:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
pre-commit install
