  • Open-source and free to use.
  • Supports multiple languages: Java, Python, JavaScript, Ruby, etc.
  • Compatible with Android and iOS platforms.
  • Doesn’t require access to app source code or recompilation.
  • Works with real devices, emulators, and simulators.

3. What Are the Limitations of Appium?

  • Does not support running multiple tests simultaneously on one device.

  • Android SDK
  • Appium server or Appium Desktop
  • Selenium client libraries (for your language)
  • IDE like Eclipse or IntelliJ
  • Test device or emulator/simulator

5. What Is an Appium Session?

An Appium session begins when a client sends a set of desired capabilities to the server. These define how the server should launch the app and which platform to use.

6. How to Check Appium Version?

appium -v

7. How to Find XPath in Appium?

Use tools like UIAutomatorViewer for Android or Appium Inspector for iOS to inspect UI elements and extract XPath or other locators.

8. What Is Appium Inspector?

Appium Inspector is a graphical tool that lets you explore your mobile app’s UI structure, view attributes, and generate locators like XPath, ID, or class name.

9. How to Use Index in XPath?

(//android.widget.TextView)[3]

10. What Is the Role of the DOM in Appium?

DOM (Document Object Model) is a structured representation of UI elements. Appium interacts with this structure to locate and manipulate elements during testing.

11. What’s the Difference Between Appium and Selenium?

Feature Selenium Appium
Usage Web applications Mobile apps (Android/iOS)
Platform Browsers Mobile OS
Framework WebDriver WebDriver + Mobile JSON Wire

12. What Programming Languages Does Appium Support?

  • Java
  • Python
  • JavaScript
  • Ruby
  • C#
  • PHP
  • Objective-C

13. What Is a Resource ID?

driver.findElementById("com.example:id/button");

14. What Is a Tap Method in Appium?


TouchAction action = new TouchAction(driver);
action.tap(TapOptions.tapOptions().withElement(ElementOption.element(el))).perform();

15. How to Compare Dimensions?

Dimension size = driver.manage().window().getSize();

16. How to Scroll in Android?


driver.findElement(MobileBy.AndroidUIAutomator(
  "new UiScrollable(new UiSelector()).scrollIntoView(text(\"Your Text\"));"));

17. What Is XCUITest?

XCUITest is Apple’s testing framework for iOS apps. Appium uses XCUITest driver to automate iOS applications.

18. How to Test an Android App Using Appium?

  1. Connect your Android device or launch an emulator.
  2. Install the APK or provide the appPackage and appActivity.
  3. Configure desired capabilities.
  4. Start the Appium server.
  5. Run your test script.

19. What Are Desired Capabilities?


{
  "platformName": "Android",
  "deviceName": "Pixel_5",
  "appPackage": "com.example",
  "appActivity": ".MainActivity"
}

20. What Is Appium Architecture?

Appium uses a client-server architecture. The client (your script) sends commands via WebDriver to the Appium server, which then executes them on the mobile OS using drivers like UIAutomator2 or XCUITest.

21. What Is UIAutomator2?

UIAutomator2 is a testing framework by Google for Android apps. It offers improved stability, faster execution, and support for Android 5.0+.

22. Can Appium Be Used for Performance Testing?

23. How Does Appium Handle Different Screen Sizes?

Appium supports relative coordinates, percentages, and screen resolution detection to ensure compatibility with different screen sizes.

24. How to Start Appium Server Programmatically?


AppiumServiceBuilder builder = new AppiumServiceBuilder();
builder.withIPAddress("127.0.0.1").usingPort(4723);
AppiumDriverLocalService service = AppiumDriverLocalService.buildService(builder);
service.start();

25. How to Handle Gestures in Appium?


TouchAction swipe = new TouchAction(driver);
swipe.press(PointOption.point(500, 1000))
     .waitAction(WaitOptions.waitOptions(Duration.ofSeconds(2)))
     .moveTo(PointOption.point(500, 500))
     .release()
     .perform();

26. Can Appium Be Used for Flutter or React Native Apps?

Yes. Appium supports testing Flutter and React Native apps using custom drivers like appium-flutter-driver and additional plugins.

27. What Is the Difference Between Native, Hybrid, and Web Apps in Appium?
