When someone talks about the mobile application testing industry, Appium is the name that comes to our mind.
As you would know, that every day, tons of mobile applications are being made. To get a license or make it suitable, the developer of that mobile application would have to run a test on them. Hence they will go to a place where the testing of mobile applications is being done. Appium is one such place. With a growing number of mobile application developers, the industry is booming. To provide an efficient working of this kind of service, the company is looking for a credible workforce.
Although they are putting a lot of effort and energy into finding the right person. So if you are thinking about getting the job, you gotta have to clear the interview and prove that you are good enough for the job.
As you can guess the interview would be one of the hardest parts of the getting the job process and that’s where you have to put a lot of effort as well. But the interview can be a little intimidating and you can be nervous as well. But you can get a good chance to clear the interview if you do know what kind of questions would be asked in the interview.
How will you know that? We’re here for that purpose. Here we have included several questions that can be asked in an Appium interview. We have listed these questions only to get you an idea of what you can expect in the interview.
Take a look at the following Appium Interview Questions and try to answer them as well.

Appium Interview Questions For 5 Years Experience
Q.1 Mention what are the basic requirement for writing Appium tests?AnsFor writing Appium tests you require,–Driver Client: Appium drives mobile applications as though it were a user. Using a client library you write your Appium tests which wrap your test steps and sends to the Appium server over HTTP.Appium Session: You have to first initialize a session, as such Appium test takes place in the session. Once the Automation is done for one session, it can be ended and wait for another sessionDesired Capabilities: To initialize an Appium session you need to define certain parameters known as “desired capabilities” like PlatformName, PlatformVersion, Device Name and so on. It specifies the kind of automation one requires from the Appium server.Driver Commands: You can write your test steps using a large and expressive vocabulary of commands.
Q.2 Mention what are the possible errors one might encounter using Appium?Ans:The possible errors one might face in Appium includes–Error 1: The following desired capabilities are needed but not provided: Device Name, platformNameError 2: Could not find adb. Please set the ANDROID_HOME environment variable with the Android SDK root directory pathError 3: openqa.selenium.SessionNotCreatedException: A new session could not be createdError 4: How to find DOM element or XPath in a mobile application?
Q.3 Do you need a server machine to run tests on Appium?Ans:No, you don’t need server machine to run tests on Appium. Appium facilitates a 2-tier architecture where a test machine connects to a test server running Appium and automating the whole thing. You can have Appium running on the same machine where your test runs.
Q.5 Mention what are the most difficult scenarios to test with Appium?Ans:The most difficult scenario to test with Appium is data exchange.
Q.6 While using Appium can I run my tests in a multithreaded environment?Ans: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.
Q.7 In Android, do you need an app’s .apk to automate using Appium or you also need app in my workspace?Ans:In Android, you only need .apk file to automate using Appium.
Q.8 Explain what is Appium package master? How to create package?Ans:Appium package master is a set of tools manage and create appium packages. For example to create package you can use the code–# using es7/babe1–Gulp create-package –n <package-name>–#regular es5–Gulp create-package —nobabe1 –n <package-name>–The package will be generated in the out/<package-name>
Q.9 Explain how test frameworks are supported by Appium?Ans:Appium does not support test framework as such there is no need to support them. Appium can be used with any frameworks you want.
Appium Interview Questions For 3 Years Experience
Q.1 Explain what is Appium?Ans:Appium is a freely distributed open source mobile application UI Testing framework.
Q.2 List out the Appium abilities?Ans:Appium abilities are–Test WebProvides cross-platform for Native and Hybrid mobile automationSupport JSON wire protocolIt does not require recompilation of AppSupport automation test on physical device as well as similar or emulator bothIt has no dependency on mobile device
Q.3 List out the pre-requisite to use APPIUM?Ans:Pre-requisite to use APPIUM is–ANDROID SDKJDKTestNGEclipseSelenium Server JARWebdriver Language Binding LibraryAPPIUM for WindowsAPK App Info On Google Playjs
Q.4 List out the limitations of using Appium?Ans:Appium does not support testing of Android Version lower than 4.2Limited support for hybrid app testing. E.g., not possible to test the switching action of application from the web app to native and vice-versaNo support to run Appium Inspector on Microsoft Windows
Q.5 Explain how to find DOM element or xPath in a mobile application?Ans:To find the DOM element use “UIAutomateviewer” to find DOM element for Android application.
Q.6 Explain the design concept of Appium?Ans:Appium is an “HTTP Server” written using Node.js platform and drives iOS and Android session using Webdriver JSON wire protocol. Hence, before initializing the Appium Server, Node.js must be pre-installed on the systemWhen Appium is downloaded and installed, then a server is setup on our machine that exposes a REST APIIt receives connection and command request from the client and execute that command on mobile devices (Android / iOS)It responds back with HTTP responses. Again, to execute this request, it uses the mobile test automation frameworks to drive the user interface of the apps. Framework likeApple Instruments for iOS (Instruments are available only in Xcode 3.0 or later with OS X v10.5 and later)Google UIAutomator for Android API level 16 or higherSelendroid for Android API level 15 or less
Q.8 Explain the pros and cons of Appium?Ans:Pros:–For programmer irrespective of the platform, he is automating ( Android or iOS) all the complexities will remain under single Appium serverIt opens the door to cross-platform mobile testing which means the same test would work on multiple platformsAppium does not require extra components in your App to make it automation friendlyIt can automate Hybrid, Web and Native mobile applicationsCons:–Running scripts on multiple iOS simulators at the same time is possible with AppiumIt 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
Q.9 Explain what is APPIUM INSPECTOR?Ans: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.

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.
Q9. Name the Appium inspector.Ans:Just like a selenium IDE playback and record tool, Appium consist of an inspector that is used to record and playback. With the help of this, you can record and play native application behaviour which is achieved
