Unit Test App

ESP-IDF unit tests are run using Unit Test App. The app can be built with the unit tests for a specific component. Unit tests are in test subdirectories of respective components.

Building Unit Test App

CMake

Follow the setup instructions in the top-level esp-idf README.
Set IDF_PATH environment variable to point to the path to the esp-idf top-level directory.
Change into tools/unit-test-app directory
idf.py menuconfig to configure the Unit Test App.
idf.py -T <component> -T <component> ... build with component set to names of the components to be included in the test app. Or idf.py -T all build to build the test app with all the tests for components having test subdirectory.
Follow the printed instructions to flash, or run idf.py -p PORT flash.
Unit test have a few preset sdkconfigs. It provides command idf.py ut-clean-config_name and idf.py ut-build-config_name (where config_name is the file name under unit-test-app/configs folder) to build with preset configs. For example, you can use idf.py -T all ut-build-default to build with config file unit-test-app/configs/default. Built binary for this config will be copied to unit-test-app/output/config_name folder.
You may extract the test cases presented in the built elf file by calling ElfUnitTestParser.py <your_elf>.

Flash Size

The unit test partition table assumes a 4MB flash size. When testing -T all, this additional factory app partition size is required.

If building unit tests to run on a smaller flash size, edit partition_table_unit_tests_app.csv and use -T <component> <component> ... or instead of -T all tests don't fit in a smaller factory app partition (exact size will depend on configured options).

Running Unit Tests

The unit test loader will prompt by showing a menu of available tests to run:

Type a number to run a single test.
* to run all tests.
[tagname] to run tests with "tag"
![tagname] to run tests without "tag" (![ignore] is very useful as it runs all CI-enabled tests.)
"test name here" to run test with given name

Testing Unit Tests with CI

For now we prefer to use component-based unit test to test in CI. Running unit-test-app in CI is being deprecated.
