This article mainly introduces the experience of using pywinauto automated testing. The sample code in the article is very detailed. It has a certain reference learning value for everyone's study or work. Friends who need it, follow the editor to learn together.
When developing Windows applications, we often need to test to ensure the quality and stability of the program. Manual testing is a common method, but it is very time-consuming and cumbersome, especially for large-scale applications, the testing workload is very heavy. Therefore, we need automated testing tools to help us improve testing efficiency and accuracy.
pywinauto is a powerful Python library that helps us automate testing of Windows applications. pywinauto can simulate the user's mouse and keyboard operations on the Windows operating system, as well as read and manipulate the properties and methods of window controls. Using pywinauto, we can easily write scripts to simulate user actions for automated testing.
Install pywinauto
Before using pywinauto, we need to install it first. You can use pip to install pywinauto:
pip install pywinauto
Automated testing with pywinauto
Let's look at a simple example to demonstrate how to use pywinauto for automated testing. We will use the Calculator application that comes with Windows as a test object.
First, we need to launch the Calculator application. You can use the Application class of pywinauto to achieve this function:
frompywinautoimportApplicationapp = Application().start("calc.exe")
The above code will start the calculator application and store its handle in the app variable.
Next, we need to get a handle to the calculator window. You can use the find_window function of pywinauto to find the window:
dlg = app['计算器']
The code above will look for a window named "Calculator" and store its handle in the dlg variable.
Now, we can start simulating user actions. Suppose we need to test the addition function of the calculator, we can follow the steps below:
Click the number "1" button.
dlg['1'].click()
Click the "+" button.
dlg['+'].click()
Click the number "2" button.
dlg['2'].click()
Click the "=" button.
dlg['='].click()
Verify that the result of the evaluation is "3".
result = dlg['CalculatorResults'].children()[0].window_text()
assert result == '3'
The code above will take the text in the calculator result box and compare it to the expected result "3". If the two are equal, then the test passes.
The full test script looks like this:
from pywinauto import Application
app = Application().start("calc.exe")
dlg = app['计算器']
dlg['1'].click()
dlg['+'].click()
dlg['2'].click()
dlg['='].click()
result = dlg['CalculatorResults'].children()[0].window_text()
assert result == '3'
Through the above example, we can see that pywinauto is very easy to use, and you don't need to master too many APIs, you only need to master some basic operations to complete automated testing.
In this article, we covered how to use pywinauto for automated testing. pywinauto is a powerful Python library that can help us simulate the user's mouse and keyboard operations on the Windows operating system, as well as read and manipulate the properties and methods of window controls. Using pywinauto, we can easily write scripts to simulate user actions for automated testing.
