# Setting Up the Environment

Basic Test Framework Environment

Environment	Operating System	Linux Extended Component	Python	Python Plug-ins	NFS Server	HDC
Version	Ubuntu 18.04 or later	libreadline-dev	3.7.5 or later	- pySerial 3.3 or later - Paramiko 2.7.1 or later - Setuptools 40.8.0 or later - rsa4.0 or later	haneWIN NFS Server 1.2.50 or later, or NFS v4 or later	1.1.0 or later
Description	Provides code build environment.	Plug-in used to read commands.	Language used by the test framework.	- pySerial: supports Python serial port communication. - Paramiko: allows Python to use SSH. - Setuptools: allows Python packages to be created and distributed easily. - rsa: implements RSA encryption in Python.	Enables devices to be connected through the serial port.	A tool that enables devices to be connected through the HarmonyOS Device Connector (HDC).

Install the HDC tool if the device supports HDC connections. For details about the installation process, see Readme.

Checking the Environment

Check Item	Operation	Expected Result
Whether Python is successfully installed	Run the python --version command.	The Python version is 3.7.5 or later.
Whether Python plug-ins are successfully installed	Go to the test/developertest directory and run start.bat or start.sh.	The >>> prompt is displayed.
NFS server status (for the devices that support only serial port output)	Log in to the development board through the serial port and run the mount command to mount the NFS.	The file directory can be mounted.
Whether HDC tool is successfully installed	Run the hdc_std -v command.	The HDC version is 1.1.0 or later.
