+# Component Test
+
+The purpose of this test suite is to verify the basic components of WAMR work well in combination. It is highly recommended to run pass all suites before each commitment.
+
+Prerequisites
+==============
+- clang is available to build wasm application.
+- python is installed to run test script.
+
+
+Run the test
+=============
+```
+start.py [-h] [-s SUITE_ID [SUITE_ID ...]] [-t CASE_ID [CASE_ID ...]]
+              [-n REPEAT_TIME] [--shuffle_all]
+              [--cases_list CASES_LIST_FILE_PATH] [--skip_proc]
+              [-b BINARIES] [-d] [--rebuild]
+```
+It builds out the simple project binary including WAMR runtime binary ```simple``` and the testing tool ```host_tool``` before running the test suites.
+
+Test output is like:
+```
+Test Execution Summary:
+        Success:              8
+        Cases fails:          0
+        Setup fails:          0
+        Case load fails:      0
+
+
+------------------------------------------------------------
+The run folder is [run-03-23-16-29]
+that's all. bye
+kill to quit..
+Killed
+```
+
+The detailed report and log is generated in ```run``` folder. The binaries copy is also put in that folder.
+
+Usage samples
+==============
+
+Run default test suite:
+</br>
+```python start.py```
+
+Rebuild all test apps and then run default test suite:
+</br>
+```python start.py --rebuild```
+
+Run a specified test suite:
+</br>
+```python start.py -s 01-life-cycle```
+
+Run a specified test case:
+</br>
+```python start.py -t 01-install```

+The description of each case in the test suites, should add descriptions in this file when new cases created in the future.
+
+suite 01-life-cycle:
+case 01-install:
+    install or uninstall apps for times and query apps to see if the app list is expected.
+case 02-request:
+    send request to an app, the app will respond specific attribute objects, host side should get them.
+case 03-event:
+    register event to an app, the app will send event back periodically, host side should get some payload.
+case 04-request_internal:
+    install 2 apps, host sends request to app2, then app2 sends request to app1, finally app1 respond specific payload to host, host side will check it.
+case 05-event_internal:
+    install 2 apps, host sends request to app2, then app2 subscribe app1's event, finally app1 respond specific payload to host, host side will check it.
+case 06-timer:
+    host send request to an app, the app then start a timer, when time goes by 2 seconds, app will respond specific payload to host, host side will check it.
+case 07-sensor:
+    open sensor in app and then config the sensor in on_init, finally app will respond specific payload to host, host side will check it.
+case 08-on_destroy:
+    open sensor in app in on_init, and close the sensor in on_destroy, host should install and uninstall the app successfully.
