Appium Interview Questions for Freshers

1. What is Appium?

Appium is a tool that helps us test applications on Android and iOS devices. It works with Android and iOS apps, no matter if they are simple or a mix of things. People who test apps use Appium to make the app do things like a person would using Appium.

2. What are the important features of the Appium testing tool?

Some of the main features that make Appium popular are:

• The Appium tool works on both Android and iOS using the code.
• No need to change or modify the application code for the Appium tool.
• It allows developers to use languages like Java, Python, and JavaScript.
• It supports testing on real devices as well as emulators and simulators. 

3. Explain the architecture of Appium.

Appium works as a server built on Node.js. It receives requests from the client side (test scripts) and processes them.

• It uses the WebDriver protocol to communicate.
• Converts commands into platform-specific actions.
• Runs those actions on Android or iOS devices.

This setup allows smooth communication between your test scripts and the mobile device.

4. What are Desired Capabilities?

Desired Capabilities are a set of key-value pairs used to start a test session.

• They define device and app details.
• Examples include platformName, deviceName, automationName, and app path.
• Sent from the client to the Appium server before execution.

5. How is Appium different from Selenium?

Appium and Selenium both use WebDriver, but they serve different purposes.

• Selenium is mainly used for web application testing.
• Appium is designed for mobile app testing.
• Appium supports gestures like swipe and tap, which Selenium does not.

6. What are Native, Web, and Hybrid Apps?

Mobile apps are generally divided into three types for the Appium tool:

• Native Apps: Built for a platform using platform languages for the Appium tool.
• Web Apps: Accessed through browsers like Chrome or Safari for the Appium tool.
• Hybrid Apps: Combine web features using a wrapper for the Appium tool.

7. What is the role of Appium Inspector?

Appium Inspector is a tool. It lets you look at the parts of an app and find what makes them unique, like a special ID or a long address. You can also use it to record what you do to make test scripts.

8. What are the different types of waits in Appium?

Appium provides wait mechanisms. These handle delays:

• Implicit Wait: Waits for a certain time to find elements for Appium.
• Explicit Wait: It delays execution until the required condition is fulfilled.

9. What is the default automation engine used by Appium?

Appium uses different engines based on the platform:

• Android uses UIAutomator2.
• iOS uses XCUITest.

These engines help execute automation commands efficiently.

10. What are the ways to find elements in Appium?

Elements in Appium can be located using different strategies:

• Accessibility ID (most recommended)
• ID and Class Name
• XPath
• AndroidUIAutomator and iOSNsPredicateString

11. What are the common exceptions in Appium?

While working with the Appium tool you may face some errors for the Appium tool:

• NoSuchElementException – Element is not found for the Appium tool.
• SessionNotFoundException – Session is. Not created for the Appium tool.
• StaleElementReferenceException – Element is no longer available.

12. What is the difference between findelement and findelements?

The difference is simple for the Appium tool:

• findElement returns one element or throws an error if not found for the Appium tool.
• findElements returns a list of elements or an empty list in Appium.

13. How do you handle gestures like scrolling or swiping?

To make an app scroll or swipe, you use a tool in Appium. This tool is called TouchAction. With TouchAction, you can make an app do things like tap, press, swipe, and scroll. This makes it seem like a real person is using the app. Appium helps you do these things.

14. What is the prerequisite to run an Android app in Appium?

Before running tests for the Appium tool, you need:

• JDK (Java Development Kit)
• Android SDK with environment variables set.
• Node.js installed.
• Appium Server setup.
• A real device or emulator with USB debugging enabled.

15. What distinguishes an emulator from a simulator?

Both are used for testing without a real device:

• An emulator is used for Android testing.
• Simulator is used for iOS testing.
• Both replicate device behavior on your system.

Appium Interview Questions for Experienced Candidates

1. How do you implement the Page Object Model (POM) in Appium?

The Page Object Model (POM) helps cleanly organize your test code. In Appium, you create separate classes for each app screen.

• Use annotations like @AndroidFindBy or @iOSXCUITFindBy to locate elements
• Keep UI elements and actions in the same class
• Write reusable methods for actions like click, type, etc.

This helps make the code clearer and easier to manage.

2. What are the key differences between Appium 1.x and Appium 2.x?

• Appium 1.x
  • Drivers are bundled with the server.
  • No need for capability prefixes.
  • Uses the default automation engine if not specified.
  • No plugin support.
  • Uses Appium Desktop for inspection.
  • Default server path: /wd/hub
• Appium 2.x
  • Drivers are installed separately.
  • Requires Appium: prefix for capabilities.
