-### Tests have been generated with the following code
+| Supported Targets | ESP32 | ESP32-C3 |
+| ----------------- | ----- | -------- |
+
+# esp_hid unit tests
+
+The unit tests are currently run only on the chips listed above just to save CI resources. If you are adding some tests which need to run on a different chip, update [.build-test-rules.yml](../.build-test-rules.yml), adding the chip you need.
+
+When adding new test cases, check if the `depends_components` list in `.build-test-rules.yml` needs to be updated to include additional components. The test app will only be built and tested when these components are modified.
+
+To build and run this test app, using esp32c3 target for example:
+
+```bash
+idf.py set-target esp32c3
+idf.py build flash monitor
+```
+
+To run tests using pytest:
+
+```bash
+idf.py set-target esp32c3
+idf.py build
+pytest --target=esp32c3
+```
+
+### Code used to generate tests
