4. How to automate WPF desktop programs

The following is a code example for automated testing of WPF applications using Python and WinAppDriver:

First, make sure you have the necessary libraries installed, including  Appium-Python-Client and  selenium. It can be installed using the following command:

pip install Appium-Python-Client selenium

Next, create a Python script that imports the necessary libraries and sets up the test environment:

from appium import webdriver

# 设置 WinAppDriver 的路径
desired_caps = {
    "app": r"C:\Path\To\Your\WPF\Application.exe",
    "platformName": "Windows",
    "deviceName": "WindowsPC"
}

# 启动 WinAppDriver 服务
driver = webdriver.Remote(command_executor="http://127.0.0.1:4723", desired_capabilities=desired_caps)

In the above code, you need to  C:\Path\To\Your\WPF\Application.exe replace the path to your WPF application.

Next,  driver automated testing operations can be performed through objects. Here are some common example operations:

1. Find elements and click on them:

# 通过元素的名称进行查找
element = driver.find_element_by_name("ButtonName")
element.click()

1. Find elements and enter text:

# 通过元素的名称进行查找
element = driver.find_element_by_name("TextBoxName")
element.send_keys("Hello, World!")

1. Get the text content of an element:

# 通过元素的名称进行查找
element = driver.find_element_by_name("LabelName")
text = element.text
print(text)

1. Close the application:

driver.close_app()

Finally, remember to close the WinAppDriver service after testing:

driver.quit()

5. How to automate Microsoft Word

To use WinAppDriver to open Microsoft Word, you need to first find the application ID of the Word application. You can use the following steps to find the App ID of your Word application:

1. Open PowerShell.

2. Run the following command:

Get-AppxPackage -Name Microsoft.Office.Word

1. In the output, look for  PackageFamilyName the value, which has a format similar to  Microsoft.Office.Word_8wekyb3d8bbwe. This value is the application ID of the Word application.

Once you obtain the application ID of the Word application, you can use WinAppDriver and Python to open Word and perform automated testing. Here is a sample code:

from appium import webdriver

# 设置 WinAppDriver 的配置
desired_caps = {
    "platformName": "Windows",
    "deviceName": "WindowsPC",
    "app": "Microsoft.Office.Word_8wekyb3d8bbwe!Microsoft.Office.Word.Application",
    "newCommandTimeout": 300
}

# 创建 WinAppDriver 驱动对象
driver = webdriver.Remote(command_executor='http://127.0.0.1:4723', desired_capabilities=desired_caps)

# 打开 Word 应用程序
driver.launch_app()

# 进行自动化测试操作
# ...

# 关闭 Word 应用程序
driver.quit()

In the above code, you need to  "Microsoft.Office.Word_8wekyb3d8bbwe!Microsoft.Office.Word.Application" replace it with the application ID of the Word application you obtained.

launch_app() The Word application can be opened by creating a WinAppDriver driver object and calling  methods. Then, you can use the API provided by WinAppDriver to perform automated testing operations. Finally, remember to close the Word application after testing.

Please note that to run the above code, you need to start the WinAppDriver service and set the  command_executor value to the address and port of the WinAppDriver service. By default, the address of the WinAppDriver service is  http://127.0.0.1:4723.

6. How to automate web browsers

The following is a code example for automated testing of Microsoft Edge using Python and Selenium WebDriver:

First, make sure you have the necessary libraries installed, including  selenium and  msedge.selenium_tools. It can be installed using the following command:

pip install selenium msedge.selenium_tools

Next, create a Python script that imports the necessary libraries and sets up the test environment:

from msedge.selenium_tools import Edge, EdgeOptions

# 创建 EdgeOptions 对象，设置 Edge 浏览器的启动选项
options = EdgeOptions()
options.use_chromium = True

# 创建 Edge 浏览器驱动对象
driver = Edge(options=options)

# 打开 Edge 浏览器
driver.get("https://www.baidu.com")

In the above code, you can set the startup options of the Edge browser as needed. For example, you can use it  options.add_argument("headless") to implement headless mode, or use it  options.add_argument("start-maximized") to maximize the window, etc.

Next,  driver automated testing operations can be performed through objects. Here are some common example operations:

1. Find elements and click on them:

# 通过元素的 ID 进行查找
element = driver.find_element_by_id("elementId")
element.click()

1. Find elements and enter text:

# 通过元素的 ID 进行查找
element = driver.find_element_by_id("elementId")
element.send_keys("Hello, World!")

1. Get the text content of an element:

# 通过元素的 ID 进行查找
element = driver.find_element_by_id("elementId")
text = element.text
print(text)

1. Close the browser:

driver.quit()

Finally, remember to close the Edge browser after testing.

To sum up, according to the specific testing needs, the API provided by WinAppDriver can be used flexibly to perform more operations and automated testing.
