+# Integration Test Description
+
+## Case Lists
+- WiFi Standard cases for only esp32.
+- BLE Standard cases for esp32 and esp32c3.
+
+## Trigger
+- By labels:
+  - `integration_test`
+- By file changes:
+  - integration test related files
+- By bot:
+  - `@bot test with label: integration_test`
+
+## Advanced
+- There are labels can be used to run less integration test cases.
+  - These labels only take effect when the integration test has been triggered.
+  - label: `integration::wifi_only`
+    - Only run WiFi cases.
+  - label: `integration::ble_only`
+    - Only run BLE cases.
