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
withcomponent
set to names of the components to be included in the test app. Oridf.py -T all build
to build the test app with all the tests for components havingtest
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
andidf.py ut-build-config_name
(whereconfig_name
is the file name underunit-test-app/configs
folder) to build with preset configs. For example, you can useidf.py -T all ut-build-default
to build with config fileunit-test-app/configs/default
. Built binary for this config will be copied tounit-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.
