# Test Apps
|
|
|
|
This directory contains a set of ESP-IDF projects to be used as tests only, which aim to exercise various
|
|
configuration of components to check completely arbitrary functionality should it be building only, executing under
|
|
various conditions or combination with other components, including custom test frameworks.
|
|
|
|
The test apps are not intended to demonstrate the ESP-IDF functionality in any way.
|
|
|
|
## Test Apps projects
|
|
|
|
Test applications are treated the same way as ESP-IDF examples, so each project directory shall contain
|
|
|
|
- Build recipe in cmake and the main component with app sources
|
|
- Configuration files, `sdkconfig.ci` and similar (see below)
|
|
- Test executor in `ttfw_idf` format if the project is intended to also run tests (otherwise the example is build only)
|
|
- test file in the project dir must end with `_test.py`, by should be named `app_test.py`
|
|
- test cases shall be decorated with `@ttfw_idf.idf_custom_test(env_tag="...")`
|
|
|
|
## Test Apps layout
|
|
|
|
The test apps should be grouped into subdirectories by category. Categories are:
|
|
|
|
- `protocols` contains test of protocol interactions.
|
|
- `network` contains system network tests
|
|
- `system` contains tests on the internal chip features, debugging and development tools.
|
|
- `security` contains tests on the chip security features.
|
|
|
|
## CI Behavior
|
|
|
|
### Configuration Files
|
|
|
|
For each project in test_apps (and also examples):
|
|
|
|
- If a file `sdkconfig.ci` exists then it's built as the `default` CI config.
|
|
- If any additional files `sdkconfig.ci.<CONFIG>` exist then these are built as alternative configs, with the specified `<CONFIG>` name.
|
|
|
|
The CI system expects to see at least a "default" config, so add `sdkconfig.ci` before adding any `sdkconfig.ci.CONFIG` files.
|
|
|
|
- By default, every CI configurations is built for every target SoC (an `m * n` configuration matrix). However if any `sdkconfig.ci.*` file contains a line of the form `CONFIG_IDF_TARGET="targetname"` then that CI config is only built for that one target. This only works in `sdkconfig.ci.CONFIG`, not in the default `sdkconfig.ci`.
|
|
- Each configuration is also built with the contents of any `sdkconfig.defaults` file or a file named `sdkconfig.defaults.<TARGET>` appended. (Same as a normal ESP-IDF project build.)
|
|
|
|
### Test Execution
|
|
|
|
If an example test or test app test supports more targets than just `ESP32`, then the `app_test.py` file needs to specify the list of supported targets in the test decorator. For example:
|
|
|
|
```python
|
|
@ttfw_idf.idf_example_test(env_tag='Example_GENERIC', target=['esp32', 'esp32s2'])
|
|
def test_app_xyz(env, extra_data):
|
|
```
|
|
|
|
If the app test supports multiple targets but you only want some of these targets to be run automatically in CI, the list can be further filtered down by adding the `ci_target` list:
|
|
|
|
```python
|
|
@ttfw_idf.idf_example_test(env_tag='Example_GENERIC', target=['esp32', 'esp32s2'], ci_target=['esp32'])
|
|
def test_app_xyz(env, extra_data):
|
|
```
|
|
|
|
(If no ci_target list is specified, all supported targets will be tested in CI.)
|
|
|
|
## Test Apps local execution (ttfw)
|
|
|
|
All the following instructions are general. Part of them may be complemented by more particular instructions in the corresponding app's README.
|
|
|
|
### Requirements
|
|
|
|
The following requirements need to be satisfied in the IDF python virtual environment.
|
|
|
|
- ttfw needs to be in the `PYTHONPATH`. Add it like this: `export PYTHONPATH=$PYTHONPATH:$IDF_PATH/tools/ci/python_packages`
|
|
- Install all requirements from `tools/ci/python_packages/ttfw_idf/requirements.txt`: `pip install -r $IDF_PATH/tools/ci/python_packages/ttfw_idf/requirements.txt`
|
|
|
|
You should also set the port via the environment variable ESPPORT to prevent the tools from looking and iterating over all serial ports. The latter causes much trouble, currently:
|
|
|
|
```
|
|
export ESPPORT=/dev/ttyUSB<X>
|
|
```
|
|
|
|
### Execution
|
|
|
|
- Create an sdkconfig file from the relevant `sdkconfig.ci.<CONFIG>` and `sdkconfig.defaults`: `cat sdkconfig.defaults sdkconfig.ci.<CONFIG> > sdkconfig`
|
|
- Run `idf.py menuconfig` to configure local project attributes
|
|
- Run `idf.py build` to build the test app
|
|
- Run `python app_test.py` to run the test locally
|
|
|
|
## Test Apps local execution (pytest)
|
|
|
|
Some of the examples have `pytest_....py` scripts that are using the `pytest` as the test framework. For detailed information, please refer to the "Run the Tests Locally" Section under [ESP-IDF tests in Pytest documentation](../../docs/en/contribute/esp-idf-tests-with-pytest.rst)
|
|
|
|
Using `pytest` is the recommended way to write new tests. We will migrate all the test apps scripts to this new framework soon.
