## Overview
This module allows you to develop new test cases for new features, or modify existing test cases for modified features. The developers test framework helps you develop high-quality code.

2. Paramiko version: 2.7.1 or later
3. Setuptools version: 40.8.0 or later

5. Run the following command to install the serial port plug-in pySerial for Python on the local PC:
```
pip3 install pyserial
```
If the installation is successful, the following prompts are displayed:
```
Requirement already satisfied: pyserial in d:\programs\python37\lib\site-packages\pyserial-3.4-py3.7.egg (3.4)
```
6. If the device supports test result output only using the serial port, install the NFS server.
For example, to install haneWIN NFS Server 1.2.50 for Windows, download the installation package from https://www.hanewin.net/nfs-e.htm.
For Linux, run the following command:
```
sudo apt install nfs-kernel-server
```
If the installation is successful, the following prompts are 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.
```
## Using Test Framework
- \(Optional\) Install the XDevice module.
1. Go to the XDevice installation directory **test/xdevice**.
2. Open the console and run the following command:
```
python setup.py install
```
If the installation is successful, the following prompts are displayed:
```
Installed d:\programs\python37\lib\site-packages\xdevice-0.0.0-py3.7.egg
Processing dependencies for xdevice==0.0.0
Finished processing dependencies for xdevice==0.0.0
```
- Configure the developers test module in the configuration file **developertest/config/user\_config.xml**.
1. Modify basic configuration parameters of the test framework.
\[build\] \# Configure build parameters of the test case.
```
false
false
true
...
```
>![](public_sys-resources/icon-note.gif) **NOTE:**
>**example**: whether to build the test case example. The default value is **false**.
>**version**: whether to build the test version. The default value is **false**.
>**testcase**: whether to build the test case. The default value is **true**.
2. For devices that support the Harmony device connector \(hdc\), modify the configuration file as follows:
\[device\] \# Configure the device information with the **"usb-hdc"** attribute, including the test device IP address and the matched hdc port.
```
192.168.1.1
9111
```
3. For devices that only support the serial port connection, modify the configuration file as follows:
\[device\] \# Configure the serial port information with the **"ipcamera"** attribute, including the COM port and baud rate.
```
COM1
cmd
115200
8
1
1
```
- \(Optional\) Modify the configuration file **config/user\_config.xml** of the **developertest** module. If a test case has been compiled, specify the compilation output directory of the test case. In this case, the test platform will not recompile the test case.
1. Specify the output directory of the test case, that is, the compilation output directory between the **** tags.
```
/home/opencode/out/release/tests
```
2. For devices that only support serial port connection, specify the NFS directory on the PC \(**host\_dir**\) and the corresponding directory on the board \(**board\_dir**\) between the **** tags. For example:
```
D:\nfs
user
```
- Prepare the test environment. \(Check that the test environment is ready if the tested device only supports serial port connection.\)
- The system image and file system have been burnt into a development board and are running properly on the development board. For example, in system mode, device prompt **OHOS\#** is displayed during shell login, indicating that the system is running properly.
- The development host has been connected to the serial port of the development board and the network port.
- The IP addresses of the development host and development board are in the same network segment and can ping each other.
- An empty directory is created on the development host for mounting test cases through the NFS, and the NFS service is started properly.
- Run test suites.
- Start the test framework and go to the **test/developertest** directory.
1. Run the following command to start the test framework in Windows.
```
start.bat
```
2. Run the following command to start the test framework in Linux.
```
./strat.sh
```
- Select a device form.
Configure device forms based on the actual development board, for example, **developertest/config/framework\_config.xml**.
- Run test commands.
1. To query the subsystems, modules, product forms, and test types supported by test cases, run the **show** commands.
```
usage:
show productlist Querying Supported Product Forms
show typelist Querying the Supported Test Type
show subsystemlist Querying Supported Subsystems
show modulelist Querying Supported Modules
```
2. Run the execution command, where **-t** is mandatory, and **-ss** and **-tm** are optional.
```
run -t ut -ss test -tm example
```
3. Specify the parameters that can be used to execute the test suite corresponding to a specific feature or module.
```
usage: run [-h] [-p PRODUCTFORM] [-t [TESTTYPE [TESTTYPE ...]]]
[-ss SUBSYSTEM] [-tm TESTMODULE] [-ts TESTSUIT]
[-tc TESTCASE] [-tl TESTLEVEL]
optional arguments:
-h, --help show this help message and exit
-p PRODUCTFORM, --productform PRODUCTFORM Specified product form
-t [TESTTYPE [TESTTYPE ...]], --testtype [TESTTYPE [TESTTYPE ...]]
Specify test type(UT,MST,ST,PERF,ALL)
-ss SUBSYSTEM, --subsystem SUBSYSTEM Specify test subsystem
-tm TESTMODULE, --testmodule TESTMODULE Specified test module
-ts TESTSUIT, --testsuite TESTSUIT Specify test suite
-tc TESTCASE, --testcase TESTCASE Specify test case
-tl TESTLEVEL, --testlevel TESTLEVEL Specify test level
```
- See the test framework help if needed.
- Run the following command to query commands supported by the test platform:
```
help
```
- Exit the self-test platform.
- Run the following command to exit the test platform:
```
quit
```
## Test Result and Log
- Test logs and test reports are generated after you execute the test commands.
- Test result
- Reports are displayed on the console. The root path of the test result is as follows:
```
reports/xxxx-xx-xx-xx-xx-xx
```
- Test case formatting result
```
result/
```
- Test case log
```
log/plan_log_xxxx-xx-xx-xx-xx-xx.log
