Running Appium Paralelly by Using XML

Running Appium tests in parallel can significantly speed up the testing process, especially when you have a large suite of tests. To achieve this, you can use a test framework like TestNG in combination with an XML configuration file to define and manage parallel execution. Here’s a step-by-step guide to running Appium tests in parallel using TestNG and an XML configuration file:

1. Setting Up Your Project

Ensure you have the necessary dependencies in your pom.xml (if you’re using Maven):




io.appium
java-client
8.2.0




org.testng
testng
7.7.0
test

2. Writing Your Test Class

Create a test class that defines your Appium tests. Each test method can represent a different test case. Here’s a simple example:

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

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

public class AppiumParallelTest {
private AppiumDriver driver;

@BeforeClass
public void setUp() throws MalformedURLException {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("deviceName", "Android Emulator");
capabilities.setCapability("app", "/path/to/your/app.apk");

driver = new AndroidDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
}

@Test
public void testOne() {
// Your test logic here
}

@Test
public void testTwo() {
// Your test logic here
}

@AfterClass
public void tearDown() {
if (driver != null) {
driver.quit();
}
}
}

3. Configuring TestNG XML for Parallel Execution

Create a testng.xml file to configure TestNG to run tests in parallel. This file allows you to define how many threads to use and specify the test classes.

In this example:

parallel="tests" specifies that tests should run in parallel.
thread-count="2" specifies the number of threads to use for parallel execution.

4. Running Your Tests

You can run your tests using the TestNG command-line interface or through an IDE that supports TestNG. To run from the command line, use:

mvn test -Dsurefire.suiteXmlFiles=testng.xml

This command tells Maven to use the testng.xml configuration file for running the tests.

Tips for Parallel Execution

Ensure Appium server is ready: Make sure you have Appium servers running on different ports for each parallel execution instance.
Unique Device Configurations: If you are running tests on multiple devices/emulators, ensure each test configuration points to a unique device.
Thread Safety: Ensure your test code is thread-safe, especially if you have shared resources.
