  TDengine's test framework and all test cases are fully open source.
  Please refer to [this document](tests/How-To-Run-Test-And-How-To-Add-New-Test-Case.md) for how to run test and develop new test case.
-### Prepare development environment
-1.  sudo apt install
-    build-essential cmake net-tools python-pip python-setuptools python3-pip
-    python3-setuptools valgrind psmisc curl
-2.  git clone <https://github.com/taosdata/TDengine>; cd TDengine
-3.  mkdir debug; cd debug; cmake ..; make ; sudo make install
-4.  pip install src/connector/python/linux/python2 ; pip3 install

-### How to run TSIM test suite
-1.  cd \<TDengine\>/tests/script
-2.  sudo ./test.sh
-### How to run Python test suite
-1.  cd \<TDengine\>/tests/pytest
-2.  ./smoketest.sh \# for smoke test
-3.  ./smoketest.sh -g \# for memory leak detection test with valgrind
-4.  ./fulltest.sh \# for full test
->   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.
-**util/log.py**
-...
-    def info(self, info):
-        printf("%s %s" % (datetime.datetime.now(), info))
-    def sleep(self, sec):
-        printf("%s sleep %d seconds" % (datetime.datetime.now(), sec))
-        time.sleep(sec)
-    def debug(self, err):
-        printf("\\033[1;36m%s %s\\033[0m" % (datetime.datetime.now(), err))
-    def success(self, info):
-        printf("\\033[1;32m%s %s\\033[0m" % (datetime.datetime.now(), info))
-    def notice(self, err):
-        printf("\\033[1;33m%s %s\\033[0m" % (datetime.datetime.now(), err))
-    def exit(self, err):
-        printf("\\033[1;31m%s %s\\033[0m" % (datetime.datetime.now(), err))

-    def printNoPrefix(self, info):
-        printf("\\033[1;36m%s\\033[0m" % (info)

-**2.5 What util/sql.py does in detail:**
-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.
-def prepare(self):
-tdLog.info("prepare database:db")
-self.cursor.execute('reset query cache')
-self.cursor.execute('drop database if exists db')
-self.cursor.execute('create database db')
-self.cursor.execute('use db')
-...
-\# 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
-input, the error will be caught as a reasonable behavior, if not caught it will
-prove that the test failed
-def error()
-...
-\# checkRows() is used to check the number of returned lines after calling
-query(select ...) after calling the query(select ...) to check the number of
-rows of returned results.
-def checkRows(self, expectRows):
-...
-\# checkData() is used to check the returned result data after calling
-query(select ...) after the query(select ...) is called, failure to meet
-expectation is
-def checkData(self, row, col, data):
-...
-\# 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):
-...
-\# CheckAffectedRows() Check if the number of affected rows is as expected
-def checkAffectedRows(self, expectAffectedRows):
-...
