Upgrade appium automation framework to the latest 2.0

lately , Mobile terminal Automation Test Framework Appium Started a new project Appium 2.0 , The transfer of basic functions is in full swing , And has released several beta edition . GitHub You can see all the plans of this project in the near future , Most of the original functions have been completed , There are also some minor configuration and documentation work in progress .

Appium 2.0 New capabilities

Personally, I am right Appium 2.0 Very bullish on , Although it's like airtest Such a framework is also very easy to use , however Appium 2.0 Trying to create a new cross platform testing ecosystem is still very attractive . Appium Hope that in 2.0 Several important things to do are ：

• Untie all drivers. Appium 1.0 It is bound to the system , For example, Android is bound Uiautomator2、iOS The binding xcuitest, Other test drivers are cumbersome to install . Unbundling drivers after ,appium 2.0 It is very easy to add the required... From the command line driver.
• Create a perfect drivers ecology .Appium 1.0 In fact, it has the ability of cross platform testing ,iOS、android、window、Mac、flutter There are already corresponding driver have access to , But part driver Still no one uses it . Appium 2.0 Support everyone to modify and customize based on existing drivers , Even make a completely new driver to test , One line of command can be integrated into Appium, Very convenient .
• Create a perfect plug-in system . Today's mobile terminal test scenarios are changeable and complex , Testing methods for special scenarios , You often need some plug-ins with special functions , The more typical is the location and location based on graphic recognition diff Mechanism ,Appium 2.0 Support simple and easy-to-use plug-in management system , It can easily expand its original ability , More and more developers are involved , Develop plug-ins with various functions , It will push forward very quickly Appium The development of .

install Appium 2.0 matters needing attention

It took 10 A few minutes to experiment with a simple operation process , Except for a few pits , The upgrade process is still very smooth .

First step ： install node.js

Appium 2.x The version has not been officially released yet , There is no formal interface version to download , Try some fresh 2.0 New functions , Only through node install . First visit ​ ​node.org​​ Download from the official website node Environmental Science , Click on the install , Pay attention to setting environment variables during installation .

The second step ： upgrade Appium service

upgrade Appium There are two options for services , The first is global installation , This method can be operated conveniently in any directory of the system appium Instructions , But now I mainly use appium 1.x Version of , Don't want to put appium 2.0 Use as the main force , So give up this way first .

Global installation ：

Log in and copy

      
      

       
       npm install -g [email protected]
      
      
      
      

       
       
1.
      
      

The second way is to install locally , Less invasive ,Appium Will be installed in the specified directory , Enter the directory to run appium Instructions , It is more suitable for the management of multiple versions . First create a local directory appium_server, Entry directory , function ：

Log in and copy

      
      

       
       npm install [email protected]
      
      
      
      

       
       
1.
      
      

Run the local... Directly after installation appium service , Local services can directly access node_modules The directory appium Command to start , It can also be used. npx function ：

Log in and copy

      
      

       
       node_modules\.bin\appium
       
       
#  perhaps 
       
       
npx appium
      
      
      
      

       
       
1.
       
       
2.
       
       
3.
      
      

After running, you will be prompted with the default port 4723 Start the service , because 2.0 The driver and plug-in have been unbound , As an independent system , So after the server starts, it will prompt No drivers and No Plugins：

Log in and copy

      
      

       
       C:\Desktop\appium_server>node_modules\.bin\appium
       
       
[Appium] Welcome to Appium v2.0.0-beta.23 (REV HEAD)

Third parts ： Install the test driver

Appium 2 The test drivers are managed separately , No test drivers will be installed by default , adopt appium driver The subcommand manages all drivers . There are many officially available drivers at present .

Now I only install the commonly used Android driver uiautomator2 and iOS drive xcuitest：

Log in and copy

      
      

       
       appium driver install uiautomator2
       
       
appium driver install xcuitest

2.
      
      

Step four ： Start the test script

Log in and copy

      
      

       
       from appium.webdriver import Remote
       
       
caps = {
       
       
    "platformName": "Android",
       
       
    "deviceName": "Android Emulator",
       
       
    "automationName": "UiAutomator2",
       
       
    "app": file
       
       
}
       
       
driver = Remote(desired_capabilities=caps, 
       
       
                command_executor = '<http://127.0.0.1:4723>')

It should be noted that 2.0 The interface prefix of is no longer ​ ​http://127.0.0.1:4723/wd/hub,​​​ ​​/wd/hub​​ It's been removed , Direct access ip: Just the port number , If you still use the previous default address , It will prompt that the route cannot be found .

Log in and copy
