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 - Default configuration for the project
- sdkconfig.ci.<CONFIG> - Other configurations, where <CONFIG> indicates name of the configuration
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.

Test Apps local execution

Append relevant sdkconfig.ci.<CONFIG> to the sdkconfig for the configuration under test
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
