OpenHarmony provides a comprehensive auto-test framework for designing test cases. Detecting defects in the development process can improve code quality.
This document describes how to use the OpenHarmony test framework.
## Setting Up the Environment
The test framework depends on the Python running environment. Before using the test framework, set up the environment as follows:
- The test framework depends on Python. Before using the test framework, you need to set up the environment.
- For details about how to obtain the source code, see [Obtaining Source Code](../get-code/sourcecode-acquire.md).
### Environment Configuration
#### Basic Test Framework Environment
|Environment|Version|Description|
|------------|------------|------------|
|Operating system|Ubuntu 18.04 or later|Provides the build environment.|
|Linux extend component|libreadline-dev|Allows users to edit command lines.|
|Python|3.7.5 or later|Provides the programming language for the test framework.|
|Python Plug-ins|pyserial 3.3 or later<br>paramiko 2.7.1 or later<br>setuptools 40.8.0 or later<br>RSA 4.0 or later|- pyserial: supports serial port communication in Python.<br>- paramiko: allows SSH in Python.<br>- setuptools: allows creation and distribution of Python packages.<br>-RSA: implements RSA encryption in Python.|
|NFS Server|haneWIN NFS Server 1.2.50 or later or NFS v4 or later|Allows devices to be connected over a serial port.|
|HDC|1.1.0 or later|Allows devices to be connected by using the OpenHarmony Device Connector (HDC).|
#### Installation Process
1. Run the following command to install the Linux extended component libreadline:
```
sudo apt-get install libreadline-dev
```
The installation is successful if the following information is displayed:
```
Reading package lists... Done
Building dependency tree
Reading state information... Done
libreadline-dev is already the newest version (7.0-3).
0 upgraded, 0 newly installed, 0 to remove and 11 not upgraded.
```
2. Run the following command to install the setuptools plug-in:
```
pip3 install setuptools
```
The installation is successful if the following information is displayed:
```
Requirement already satisfied: setuptools in d:\programs\python37\lib\site-packages (41.2.0)
```
3. Run the following command to install the paramiko plug-in:
```
pip3 install paramiko

5. Run the following command to install the pyserial plug-in:
```
pip3 install pyserial
```
The installation is successful if the following information is displayed:
```
Requirement already satisfied: pyserial in d:\programs\python37\lib\site-packages\pyserial-3.4-py3.7.egg (3.4)
```
6. Install the NFS server if the device outputs results only through the serial port.
- For Windows, install, for example, haneWIN NFS Server 1.2.50.
- For Linux, run the following command to install the NFS server:
```
sudo apt install nfs-kernel-server
```
The installation is successful if the following information is displayed:
```
Reading package lists... Done
Building dependency tree
Reading state information... Done
nfs-kernel-server is already the newest version (1:1.3.4-2.1ubuntu5.3).
0 upgraded, 0 newly installed, 0 to remove and 11 not upgraded.
```
7. Install the HDC tool if the device supports HDC connections.
For details, see https://gitee.com/openharmony/developtools_hdc_standard/blob/master/README.md
## Checking the Installation Environment
| Check Item|Operation |Requirements |
| --- | --- | --- |
| Check whether Python is installed successfully.|Run the **python --version** command. |The Python version is 3.7.5 or later.|
| Check whether Python plug-ins are successfully installed.|Go to the **test/developertest** directory and run **start.bat** or **start.sh**.| The **>>>** prompt is displayed.|
|Check the 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. |
|Check whether the HDC is successfully installed. |Run the **hdc_std -v** command.|The HDC version is 1.1.0 or later.|

| Type | Description |
| ------------ | ------------ |
| HWTEST(A,B,C) | Use this template if the test case execution does not depend on setup or teardown. |
| HWTEST_F(A,B,C) | Use this template if the test case execution (excluding parameters) depends on setup and teardown. |

| HWTEST_P(A,B,C)| Use this template if the test case execution (including parameters) depends on setup and teardown.|
In the template names:
- *A* indicates the test suite name.
- *B* indicates the test case name, which is in the *Function*\_*No.* format. The *No.* is a three-digit number starting from **001**.
- *C* indicates the test case level. There are five test case levels: guard-control level 0 and non-guard-control level 1 to level 4. Of levels 1 to 4, a smaller value indicates a more important function verified by the test case.
Note the following:
**CAUTION**<br>
- The expected result of each test case must have an assertion.
- The test case level must be specified.
- It is recommended that the test be implemented step by step according to the template.
- The comment must contain the test case name, description, type, and requirement number, which are in the @tc.*xxx*: *value* format. The test case type @**tc.type** can be any of the following:
| Test Case Type | Code |
| ------------ | ---------- |
