->   Note1: TDengine daemon's configuration and data files are stored in
->   \<TDengine\>/sim directory. As a historical design, it's same place with
->   TSIM script. So after the TSIM script ran with sudo privilege, the directory
->   has been used by TSIM then the python script cannot write it by a normal
->   user. You need to remove the directory completely first before running the
->   Python test case. We should consider using two different locations to store
->   for TSIM and Python script.
-
->   Note2: if you need to debug crash problem with a core dump, you need
->   manually edit smoketest.sh or fulltest.sh to add "ulimit -c unlimited"
->   before the script line. Then you can look for the core file in
->   \<TDengine\>/tests/pytest after the program crash.
-
-### How to add a new test case
-
-**1. add a new TSIM test cases:**
-
-TSIM test cases are now included in the new development branch and can be
-added to the TDengine/tests/script/test.sh script based on the manual test
-methods necessary to add test cases as described above.
-
-**2. add a new Python test cases:**
-
-**2.1 Please refer to \<TDengine\>/tests/pytest/insert/basic.py to add a new
-test case.** The new test case must implement 3 functions, where self.init()
-and self.stop() simply copy the contents of insert/basic.py and the test
-logic is implemented in self.run(). You can refer to the code in the util
-directory for more information.
-
-**2.2 Edit smoketest.sh to add the path and filename of the new test case**
-
-Note: The Python test framework may continue to be improved in the future,
-hopefully, to provide more functionality and ease of writing test cases. The
-method of writing the test case above does not exclude that it will also be
-affected.
-
-**2.3 What test.py does in detail:**
-
-test.py is the entry program for test case execution and monitoring.
-
-test.py has the following functions.
-
-\-f --file, Specifies the test case file name to be executed
--p --path, Specifies deployment path
-
-\-m --master, Specifies the master server IP for cluster deployment 
--c--cluster, test cluster function
--s--stop, terminates all running nodes
-
-\-g--valgrind, load valgrind for memory leak detection test
-
-\-h--help, display help
-
-**2.4 What util/log.py does in detail:**
-
-log.py is quite simple, the main thing is that you can print the output in
-different colors as needed. The success() should be called for successful
-test case execution and the success() will print green text. The exit() will
-print red text and exit the program, exit() should be called for test
-failure.

-
-SQL.py is mainly used to execute SQL statements to manipulate the database,
-and the code is extracted and commented as follows:
-
-**util/sql.py**
-
-\# prepare() is mainly used to set up the environment for testing table and
-data, and to set up the database db for testing. do not call prepare() if you
-need to test the database operation command.

-\# query() is mainly used to execute select statements for normal syntax input
-
-def query(self, sql):

-\# error() is mainly used to execute the select statement with the wrong syntax

-...
-
-\# getData() returns the result data after calling query(select ...) to return
-the resulting data after calling query(select ...)
-
-def getData(self, row, col):
-

-\# execute() used to execute sql and return the number of affected rows
-
-def execute(self, sql):
-

-
-\# executeTimes() Multiple executions of the same sql statement
-
-def executeTimes(self, sql, times):

-
--   Test cases that already exist must pass.
-

-    and do as many iterations as possible to ensure that the test case provides

+### How to add a new test case
+
+**1. TSIM test cases:**
+
+TSIM was the testing framework has been used internally. Now it still be used to run the test cases we develop in the past as a legacy system. We are turning to use Python to develop new test case and are abandoning TSIM gradually.
+
+**2. Python test cases:**
