• Press Enter to see the list of available tests
• Enter a test number to run a specific test
• Enter * to run all tests

Extending the Tests

Adding tests to existing component

1. Create a new .cpp file in components/<component_name>/test/
2. Add the filename to the source list in components/<component_name>/test/CMakeLists.txt:

list(APPEND srcs_list "your_new_test_file.cpp")

3. Write the test cases in the new test file.

Adding new component tests

Please refer to components/esp_matter/test directory for comprehensive structure and example.

• After adding the new component tests, you need to add the component to the TEST_COMPONENTS list in CMakeLists.txt
• Append the component name to the TEST_COMPONENTS list. For example, if you add a new component called "new_component", you need to add it to the TEST_COMPONENTS list in CMakeLists.txt:

set(TEST_COMPONENTS "esp_matter new_component" CACHE STRING "List of components to test")
