 *   `DEVICE_NAME`: display name of commissioned Matter device on GHA, e.g. `m5stack`
 
+### Regression Test
+
+```shell
+$ ui-automator --commission DEVICE_NAME,PAIRING_CODE,ROOM_NAME --reg-test [--repeat <REPEAT_TIMES>]
+```
+
+*   flag `--reg-test` is required
+*   regression test need to be used with flag `--commission`
+*   regression test now only supports commissioning/decommissioning cycle
+*   defaultly, regression test will run until users use keyboard interrupt to
+    stop the process
+*   add `--repeat` to run regression test in limited times
+*   `REPEAT_TIMES`: repeated times for regression test
+
 ## Roadmap
 
 -   [x] Commissioning Matter device
 -   [x] Decommissioning Matter device
+-   [x] Regression test of cycling commissioning/decommissioning
+-   [ ] Support regression test for devices that need additionally manual
+    operations after decommissioning to recover to BLE commissioning mode
+-   [ ] Share Fabric
+-   [ ] Get pairing code when sharing fabric
