Q1: Explain what is Appium?
A1: Appium is a freely distributed open source mobile application UI Testing framework.

Q2: List out the Appium abilities?
A2: Appium abilities are

  • Test Web
  • Provides cross-platform for Native and Hybrid mobile automation
  • Support JSON wire protocol
  • It does not require recompilation of App
  • Support automation test on physical device as well as similar or emulator both
  • It has no dependency on mobile device

Q3: List out the limitations of using Appium?

  • Appium does not support testing of Android Version lower than 4.2
  • Limited support for hybrid app testing. E.g., not possible to test the switching action of application from the web app to native and vice-versa
  • No support to run Appium Inspector on Microsoft Windows

Q4: Explain how to find DOM element or xPath in a mobile application?
A4: To find the DOM element use “UIAutomateviewer” to find DOM element for Android application.

Q5: What language does Appium support?
A5: Appium support any language that support HTTP request like Java, JavaScript with Node.js, Python, Ruby, PHP, Perl, etc.

Q6: Explain what is APPIUM INSPECTOR?
A6: Similar to Selenium IDE record and Playback tool, Appium has an “Inspector” to record and playback. It records and plays native application behavior by inspecting DOM and generates the test scripts in any desired language. However, Appium Inspector does not support Windows and use UIAutomator viewer in its option.

Q7: Mention what are the most difficult scenarios to test with Appium?
A7: The most difficult scenario to test with Appium is data exchange.

Q8: While using Appium can I run my tests in a multithreaded environment?
A8: Yes, you can run the test in a multithreaded environment but you have to ensure that no more than one test runs at the same time against the same Appium server.

Q9: What are native Apps?
A9: Those Apps are written by using Android SDKs and IOS are known as Native Apps.

Q10: What are Mobile Web Apps?
A10: There are the mobile webs pages are those web apps that by are accessed with the mobile browsers. In case of IOS platform, Appium supports Safari and for the android platform, Chrome or any other built in browser is used.

Q11: What are hybrid apps?
A11: Those apps that are equipped with wrapper around the web view is known as a Hybrid app. This is native control that will facilitate the interaction with the web content.

Q12: What are the requirements to write Appium tests?
A12: There are certain basic requirements when it comes to write Appium tests and they are:-

  1. Driver client – Mobile applications are driven by Appium like that of a user. With the help of a client library Appium tests can be written and these will wrap the steps of a test and then send it Appium over the HTTP.
  2. Appium Session– Appium tests takes place within a session so it is important to initialize an appium session first. Once there is an end to the automation of a session it will be ended and wait again for the next session.
  3. The desired capabilities– In order to initialize an appium session it is very important to design some parameters which are known as desired parameters. These parameters are platform version, platform name, device name and many more. This also helps in specifying the type of automation that is required from the Appium server.
  4. Driver Command – In Appium you have the facility to write the tests by using a big and expressive collection of commands.

Q13: Name the types of errors that you can face in Appium.
A13: 1. Error type one – These types of error occurs when there is the need of desired capabilities but they are not provided. Missing of Device name or platform name is considered to be part of this error type.

2. Error type two – These types of error occurs when you cannot find adb. To avoid this type of error can be avoided by setting Android Home environment variable with Android SDK root directory path.

3. Errors type three – This falls under the category of penqa.selenium.SessionNotCreatedException which will not allow you to create a new session.

Q14: What are the most difficult scenarios that one might face while testing Appium?
A14: Data exchange is the most difficult scenario that one might face while testing Appium.

Q15: Is it possible to run tests in a multithreaded environment while you are using Appium?
A15: It is indeed possible to run tests on multithreaded environment but you have to make sure that no two tests are running simultaneously on the same Appium server.

Q16: What’s That One Point Which Made You Choose Appium For Mobile App Testing?
A16: It has a unique design which natively supports Selenium. And Selenium is one of the most used and evolving technology for automation testing. It has an open support from the global browser vendors like Google, Mozilla, and Safari. Each one of them agreed to provide their Web drivers implementing the Selenium interfaces. Next, it is cross-platform enabled, supports all popular programming languages, and webdriver makes its tests more scalable. You need to write tests once which you can run anywhere.

Q17: What Would You Prefer To Test On Real Devices Or Use Simulators/Emulators?
A17: It’s one of the most commonly asked Appium interview questions. You’ve to be little logical and practical while answering it. Don’t just simply answer “It would depend on what you need.”. Because it would be a layman answer which interview won’t expect from you. Rather you should explain it by example.

You can say something like that it’s always best to test on real devices. As it would allow you to catch errors that you may not detect otherwise. But you have to configure the device smartly with the Appium server so that it can detect the device. Sometimes the ADB, the Android debugger may disconnect from the device even if it remains plugged in. And it can cause your tests to fail. To handle such issues, you can write a module which resets the ADB after some time to re-connect the devices.

Q18: How Do The Tests Run On Simulators/Emulators?
A18: The limitation of disconnecting from the devices would never occur with the emulators. They will remain attached to the ADB. You may even set orientation and other hardware-based features that it can emulate.

Running entirely in a virtual world wouldn’t come without some limitations. Your tests would run slow as the emulators consume a lot of memory. Even they might behave intermittently during the execution.

But you can start early testing with them till you acquire the real devices.

Q19: Which Are The Test Frameworks That Appium Supports?

  • Appium doesn’t have built-in or default support for any test frameworks.
  • You can use it with many testing tools like Selenium Webdriver.
  • There are some unit test frameworks like <NUnit> and <.Net>which you can use with Appium.
  • Appium provides a driver module that’s what you need for writing test cases.

Q20: Does It Require An <.Apk> File For Automating Tests In Appium?
A20: Yes, you need the <.apk> package to automate using Appium.

Q21: Why Do The Appium Clients Exist?
A21: We have the Appium clients for 3 reasons:

1) There wasn’t time to go through a full commit and release cycle for Selenium once we’d set a release date for 1.0

2) Some of the things that Appium does, and which its users really find useful, are never going to be an official part of the new mobile spec. We want a way to make these extensions available

3) There are some behaviors whose state is as yet unknown. They might make it into the spec and get deleted from the clients, or they might be in category #2

Ultimately, the only reason for the clients will be #2. And even that is actually evidence that we are conforming to the WebDriver spec (by implementing the extension strategy it recommends) rather than departing from it. The Appium clients are the easiest and cleanest way to use Appium.

Q22: What About Performance?
A22: Appium is not a huge application and requires very little memory. Its architecture is actually pretty simple and light as Appium acts like a proxy between your test machine and each platform automation toolkit. Once up and running, Appium will listen to HTTP requests from your tests; when a new session is created, a component in Appium’s Node.js code called _proxy_ will forward these Selenium commands to active platform drivers.

In the case of Android for example, Appium will forward incoming commands to the [chromedriver] (90% of cases, Appium will not even change commands while routing them), this happens because ChromeDriver supports WebDriver and Selenium. For this reason Appium will not allocate much memory itself, you will see a lot of memory being allocated by other processes like [adb], ChromeDriver or the iOS automation toolkit (called by Appium while testing and automating).

Q23: How Can I Test Android Tablets?
A23: The best way to test on different Android emulators screen sizes is by using the different Android Emulator Skins . For instance, if you use our Platforms Configurator you’ll see the available skins for the different Android versions (e.g Google Nexus 7 HD, LG Nexus 4, Samsung Galaxy Nexus, Samsung Galaxy S3, etc). Some of these skins are tablets, for example the Google Nexus 7C is a tablet which has a very large resolution and very high density.

Q24: Explain The Pros And Cons Of Appium?
A24: Pros:

  • For programmer irrespective of the platform, he is automating ( Android or iOS) all the complexities will remain under single Appium server
  • It opens the door to cross-platform mobile testing which means the same test would work on multiple platforms
  • Appium does not require extra components in your App to make it automation friendly
  • It can automate Hybrid, Web and Native mobile applications


  • Running scripts on multiple iOS simulators at the same time is possible with Appium
  • It uses UIAutomator for Android Automation which supports only Android SDK platform, API 16 or higher and to support the older API’s they have used another open source library called Selendroid.

Q25: What Test Frameworks Are Supported By Appium?
A25: Appium does not support test frameworks because there is no need to support them! You can use Appium with all test frameworks you want. NUnit and .NET Unit Test Framework are just a few examples; you will write your tests using one of the drivers for Appium; thus your tests will interface with Appium just in terms of an external dependency. Use whatever test framework you want!

Q26: What Data Exchange Is?
A26: When I say “data exchange” I am not referring to scenarios like getting or setting the value of a textbox. I am also not referring to getting or setting the value of an element’s attribute. All these things are easy to achieve in Appium as Selenium provides commands just for those. By “data exchange” I mean exchanging information hosted by complex objects stored in different parts of your webview-based app like the window object.

Consider when you dispatch and capture events, your app can possibly do many things and the ways data flows can be handled are many. Some objects might also have a state and the state machine behind some scenarios in your app can be large and articulated. For all these reasons you might experience problems when testing.

Q27: I Don’t Want To Set Up A Whole Infrastructure For My Tests And I Don’t Want To Spend Money On Hw. Can Appium Help Me?
A27: If you think about it, what really is required from you is writing tests. Then the fact that you must deploy an Appium server somewhere is something more.

If you want to skip this part, you can rely on some web services that already deployed a whole architecture of Appium servers for your tests. Most of them are online labs and they support Selenium and Appium.

Q28: What Are The Basic Commands That I Can Use In The Selenium Protocol?
A28: Google’s Selenium provides a collection of commands to automate your app. With those commands you can basically do the following:

  • Locate web elements in your webview-based app’s pages by using their ids or class names.
  • Raise events on located elements like Click().
  • Type inside textboxes.
  • Get or set located element’s attributes.
  • Execute some Javascript code.
  • Change the context in order to test the native part of your app, or the webview. If your app uses more webviews, you can switch the context to the webview you desire. If your webview has frames or iframes inside, you can change context to one of them.
  • Detect alert boxes and dismiss or accept them.

Q29: What Mobile Web Browsers Can I Automate In The Android Emulator?
A29: Currently the only browser that can be automated in our Android emulators is the stock browser (i.e Browser). The Android stock browser is an Android flavor of ‘chromium’ which presumably implies that its behavior is closer to that of Google Chrome.

Q30: Any Tips Or Tricks To Speed Up My Test Writing Activity Or My Migration Process?
A30: Here is one piece of advice. Since your tests will mostly consist in automation tasks (if this condition is not met, you might want to reconsider using Appium), make interactions reusable! Do not write the same sub-scenarios twice in your tests, make a diagram of what your scenarios are and split them in sub activities; you will get a graph where some nodes are reachable from more than one node.

So make those tasks parametric and call them in your tests! This will make your test writing experience better even when you need to migrate from existing tests (hopefully you already did this activity for your existing suites).
