+## Building Unit Tests
 
-#### Using QEMU
+To build all unit tests:
 
--   Setup ESP32 QEMU. This will build QEMU and install necessary artifacts to
-    run unit tests.

+    $ scripts/build/build_examples.py --target esp32-qemu-tests build

+This generates a list of QEMU images in `out/esp32-qemu-tests/`
 
--   Run specific unit tests
+There is one image for each test directory (i.e. each chip_test_suite). So for
+example `src/inet/tests` builds to `out/esp32-qemu-tests/testInetLayer.img`
 
-          ```
-          idf make -C build/chip/src/crypto/tests check

+The file `out/esp32-qemu-tests/test_images.txt` contains the names of all the
+images that were built.

+## Running Unit Tests

+    $ src/test_driver/esp32/run_qemu_image.py --verbose --file-image-list out/esp32-qemu-tests/test_images.txt
