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.

@pavan_appium @TuHuynh  
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](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 ?

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.

</div>

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)”

@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.

Please set ANDROID\_HOME env variable correctly so that adb command runs correctly.
