Has anyone successfully run test scripts parallel in two or more Android devices?

It was due to some other error, now things seems to work fine. Thanks!!!. I used the framework mentioned by you:

Need a featured if you can build it for cucumber:

Need a before all kind of method

@Dhiren_Mudgil would be really helpfull if u can raise a issue on the repo https://github.com/saikrishna321/AppiumTestDistribution and provide more details. will surely look into this

YeahI have tried and its working fine for me.
can you share your code, so that I can guide you.

Thanks

@ravikr42
Need help on Selenium Grid: I am trying executes script on different mobile emulators but i can’t succeed . I have tried different tutorials but unable to succeed.

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
    performOperations(); // user function
}

public static void main(String[] args) {
    // Create object
    CalcExample calc = new CalcExample();
    calc.execute();

Hi,

I was trying out parallel or sequential execution on multiple android devices, but my scripts always ran on only one device. I finally figured out that I needed to provide unique values for - Appium Port, Bootstrap Port and Device ID (UDID) to make it work.

I have written a post about this, which you can check out below. It uses Java Thread and Runnable interface to run the test in parallel in 2 devices. The logic for parallel execution can be anything, but as mentioned above the important thing is that we pass different values for Appium Port, Bootstrap Port, Device ID (not Device Name) and Chrome Driver Port (if using Chrome Browser)

ravikr42 · November 28, 2016, 1:06am

Hi @vaibhav_khachane

Code and steps looks good. are you giving unique address and port details in node configuration file.? how are you executing scripts ? Use testNG parallel execution.

Kindly check or share the node configuration details.

Thanks
Ravi

Please share any working demo project with me… I am stuck in it since last month

Thanks @vaibhav_khachane for sharing. I will look into it and get back to you.
Please drop your mail. I will share.

@ravikr42 you may be interested in this https://github.com/saikrishna321/AppiumTestDistribution

vaibhav_khachane · November 29, 2016, 7:01am

Please share any basic example like launch application on multiple device using selenium grid. I need it.

saikrishna321 · November 29, 2016, 9:42am

@vaibhav_khachane pls take a look at the sample project, https://github.com/saikrishna321/PageObjectPatternAppium

Just connect two android devices to your machine. Clone the project and navigate to the root of the project and run the command mvn clean -Dtest=Runner test

You should see the tests running in parallel

vaibhav_khachane · November 30, 2016, 5:08am

Hi Thanks ,I am going through project and import it into eclipse and change the config file. and try to run the project, but getting an error. I am using java with TestNG for my project. I am begginer in Mobile Automation testing . So please share with me step by step process if possible.

saikrishna321 · November 30, 2016, 5:57am

Please navigate to the folder where the pom.xml is located and pls use Intellji as IDE

You can open two different terminals, the first you leave with the default host and port witch is 0.0.0.0 4723, start running your test on it.
go to the other terminal and run command: appium -a 127.0.0.1 -p 4725 (or any other host and port you like) and run the second one.

I’m working with emulators and it works for me.
