try {
IOSDriver driver = new IOSDriver(new URL("http://localhost:4723/wd/hub"), options);
// Your test code here
} catch (Exception e) {
e.printStackTrace();
}
}
}Advanced Android 12+ Capabilities in Java

import org.openqa.selenium.remote.DesiredCapabilities;
import java.net.URL;
public class Android12Configuration {
public static void main(String[] args) {
AndroidOptions options = new AndroidOptions();
options.setPlatformName("Android")
.setDeviceName("Pixel_4_API_30")
.setAutomationName("UIAutomator2")
.setApp("/path/to/your.apk")
.setSystemPort(8200)

} catch (Exception e) {
e.printStackTrace();
}
}
}Cross-Platform Capabilities for Unified Testing
Creating test suites that work across both iOS and Android requires careful configuration of cross-platform capabilities. These capabilities ensure consistent test behavior while accounting for platform-specific differences. The platformName capability is essential for identifying the target platform, while the app capability specifies the application under test, which may need to be different for each platform.
When implementing cross-platform testing, consider these best practices:
- Use conditional logic to set platform-specific capabilities
- Implement capability inheritance to reduce redundancy
- Create capability profiles for common device/OS combinations
The serverPath and wdaStartupRetries capabilities can help manage test execution across different platforms, while the newCommandTimeout capability ensures responsive test execution. For cross-platform testing frameworks, it's beneficial to create capability builders that can generate appropriate configurations based on the target platform.
import io.appium.java_client.AppiumDriver;
import io.appium.java_client.remote.MobileCapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import java.net.URL;
import java.util.HashMap;
import java.util.Map;
public class CrossPlatformConfiguration {
public static void main(String[] args) {
Map<String, Object> capabilities = new HashMap<>();
capabilities.put(MobileCapabilityType.PLATFORM_NAME, "Android"); // or "iOS"
capabilities.put(MobileCapabilityType.DEVICE_NAME, "Pixel_4_API_30"); // or "iPhone 13 Pro"
capabilities.put(MobileCapabilityType.APP, "/path/to/your.apk"); // or .app for iOS
capabilities.put(MobileCapabilityType.AUTOMATION_NAME, "UIAutomator2"); // or "XCuiTest" for iOS
capabilities.put(MobileCapabilityType.NEW_COMMAND_TIMEOUT, 120);
capabilities.put(MobileCapabilityType.NO_RESET, true);
// Platform-specific capabilities
if ("iOS".equals(capabilities.get(MobileCapabilityType.PLATFORM_NAME))) {
capabilities.put("wdaStartupRetries", 4);
capabilities.put("useNewWDA", true);
} else {
capabilities.put("systemPort", 8200);
capabilities.put("autoGrantPermissions", true);
}
try {
