Foreword:

Appium is a popular automated testing tool for mobile applications, which can be used to test Android applications. TestNG is a powerful testing framework that provides rich features and flexible configuration options to help testers write and execute test cases.

1. Test class 

package com.testerhome;

import io.appium.java_client.android.AndroidDriver;

import java.net.MalformedURLException;
import java.net.URL;

import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.AfterClass;

public class Suite1 {
    public String port;
    public String udid;
    private AndroidDriver driver;

  @Test
  public void switches() throws InterruptedException {
      WebElement sound = driver.findElementByAndroidUIAutomator("new UiSelector().text(\"Sound\")");
      sound.click();
      System.out.println("checked");
      Thread.sleep(2000);
      System.out.println(Thread.currentThread());
  }

  @BeforeSuite
  @Parameters({ "port", "udid" })
  public void beforeSuite(String port, String udid) {
      this.port = port;
      this.udid = udid;

  }

  @BeforeClass
  public void beforeClass() throws MalformedURLException{
        System.out.println(“port is ” + port + “, udid is " + udid);

        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName","device");
        capabilities.setCapability("automationName","Appium");
        capabilities.setCapability("platformVersion", "4.4");
        capabilities.setCapability("udid", udid);
        capabilities.setCapability("appPackage", "com.android.settings");
        capabilities.setCapability("appActivity", ".Settings");
        driver = new AndroidDriver(new URL("http://127.0.0.1:" + port + "/wd/hub"), capabilities);

  }

  @AfterClass
  public void afterClass() {
      driver.quit();

  }

}

2. Connect two Android devices or start two virtual machines

adb devices
Get udid using

3. Create two new testng.xml under the project path

testng1.xml

<?xml version="1.0" encoding="UTF-8"?>  
<suite name="Suite1">
  <parameter name = "port" value = "4723"/>
  <parameter name = "udid" value = "emulator-5554"/>
  <test name="Test">  
    <classes>  
      <class name="com.testerhome.Suite1"/> 
    </classes>  
  </test>  
</suite>  

testng2.xml

<?xml version="1.0" encoding="UTF-8"?>  
<suite name="Suite2">
  <parameter name = "port" value = "4725"/>
  <parameter name = "udid" value = "emulator-5556"/>
  <test name="Test">  
    <classes>  
      <class name="com.testerhome.Suite1"/> 
    </classes>  
  </test>  
</suite>  

4. Open two appium servers 

If the command line starts with parameters
appium -p 4723 -bp 4724
appium -p 4725 -bp 4726

If it is a graphical interface, modify:
first:
Port in General Settings, change to 4723
Bootstrap Port in Android Settings, change to 4724

The second one:
Port in General Settings, changed to 4725
Bootstrap Port in Android Settings, changed to 4726

5. Export dependencies 

Because it is created with a maven project, first export the dependencies to the lib folder under the project path
mvn dependency:copy-dependencies -DoutputDirectory=lib

6. Execute the test

First execute it serially with Maven to compile the Class file
mvn clean test
and then
java -classpath ".\target\test-classes" -Djava.ext.dirs=lib org.testng.TestNG -suitethreadpoolsize 2 testng1.xml testng2.xml
if the TestNG environment variable is not configured
java -classpath ".\target\test-classes;D:\Programs\testng-6.8\testng-6.8.jar" -Djava.ext.dirs=lib org.testng.TestNG -suitethreadpoolsize 2 testng1.xml testng2.xml

  As someone who has been here, I also hope that everyone will avoid some detours

Here I will share with you some necessities of the way forward in automated testing, hoping to help you.

(software testing related materials, automated testing related materials, technical questions and answers, etc.)

I believe it can make you better progress!
