Appium Parallel Execution

I found out some reference links to follow, I will give a try first then come back to you if I face any issue.

Thanks man.

Just FYI I have tried to run same set of tests on iOS Simulator and Real device connected to same machine at the same time.

I’m starting the grid and registering the appium instance in java code using the below snippet:

@BeforeSuite
public void startgrid() throws IOException, InterruptedException{
Runtime.getRuntime().exec(“java -jar /Users/dd/Selenium/selenium-server-standalone-2.53.1.jar -role hub http://127.0.0.1:4444/grid”);
Thread.sleep(50000);
Runtime.getRuntime().exec(“appium -a 127.0.0.1 -p 4723 --no-reset --bootstrap-port 4730 -U device111 --nodeconfig /Users/dd/workspace/SampleAutomation/jsonFiles/node_config_1.json”);
Runtime.getRuntime().exec(“appium -a 127.0.0.1 -p 4725 --no-reset --bootstrap-port 4730 -U device222 --nodeconfig /Users/dd/workspace/SampleAutomation/jsonFiles/node_config_3.json”);
Thread.sleep(50000);
}

First time when I run the test , grid is starting and the two appium instances are getting registered and test runs as I expected. Next time when I do mvn test it is showing the following execption
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
Build info: version: ‘2.53.0’, revision: ‘35ae25b1534ae328c771e0856c93e187490ca824’, time: '2016-03-15 10:43:46’

Can u say how to stop the grid once the test is completed ?

I think you just need to kill appium is ok.

Taskkill /F /IM node.exe

Am I right @pavan_appium ?

in @afterSuite we need to give this command??

With me, yes, and I used below method:

==

public static void stopServer() {
    CommandLine command = new CommandLine("cmd");
    command.addArgument("/c");
    command.addArgument("Taskkill /F /IM node.exe");

    try {
        DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();
        DefaultExecutor executor = new DefaultExecutor();
        executor.setExitValue(1);
        executor.execute(command, resultHandler);
        Thread.sleep(5000);

        System.out.println("------> Appium server stopped.");
    } catch (IOException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
        e.printStackTrace();
    }

}

@TuHuynh
what u have specifed is for Windows machine ?? I’m using mac and wat about it?

And I also tried

@AfterSuite
public void appstop() throws IOException {
Runtime.getRuntime().exec(“killall node”);
}

This also didnt work out.

Sorry for late reply.
Yes you need to kill Appium as initiating new session is a bit issue with current build
if you have to kill appiumon mac then use command “pkill -f appium (or node)”

can i gve this in aftersuite as I mentioned below?
@AfterSuite
public void appstop() throws IOException {
Runtime.getRuntime().exec(“pkill -f appium”);
}

@pavan_appium: Hi Pavan, I am trying selenium grid but couldn’t succeed in it. I have referred so many tutorials till stuck in it… Please share any document which describe step by step process for implementation for selenium grid. I want to implement it for IOS and Android platform. Thanks in Advance.


In screenshot no 1. how to procced next step
In Screenshot no. 2 , while executing code , it displayed error

Please set ANDROID_HOME env variable correctly so that adb command runs correctly.

@pavan_appium:- i have set env variable fot ANDROID_HOME

let me know if any issue in screenshot

Did you add ANDROID_HOME in PATH Variable too ?

yes

Please give a try with setting ANDROID_HOME in your Eclipse

In [Run configuration] please set as attached pic.

@TuHuynh: Tried but doesn’t work. Other script are runnung fine. I have use following procedure
1)Started Hub
2)Started Node
3)try to execute script

Let me know if i am missing anything

I am trying demo example:
Code 1:- CalcExample .java

package example;
import java.io.File;
import libs.BaseTest;
import org.openqa.selenium.By;
public class CalcExample extends BaseTest{

public CalcExample(){
}

public CalcExample(int deviceNum) {
    super(deviceNum);
}

public void performOperations() {
    
    try
    {
        driver.findElement(By.id("com.android2.calculator3:id/cling_dismiss")).click();
        driver.findElement(By.id("com.android2.calculator3:id/digit5")).click();
        driver.findElement(By.id("com.android2.calculator3:id/plus")).click();
        driver.findElement(By.id("com.android2.calculator3:id/digit9")).click();
        driver.findElement(By.id("com.android2.calculator3:id/equal")).click();
        String num = driver.findElement(By.xpath("//android.widget.EditText[@index=0]")).getText();
        System.out.println("Result : "+num);
        driver.closeApp();
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
}

public void run(){
    File app = new File("C:\\AndroidCalculator.apk");
    String appPath = app.getAbsolutePath();
    createDriver(appPath); // create devices
