Appium Interview Questions
1) What is Appium?
• Appium is an open-source tool for automating Native, Mobile Web, in addition to Hybrid applications on iOS in addition to Android platforms.
• Appium is "cross-platform": it allows us to write tests against multiple platforms (iOS, Android), using the same API. This enables code reuse betwixt iOS in addition to Android testsuites.
• Appium was launched inwards 2012.
2) What are Native Apps?
Native apps are those written using the iOS or Android SDKs.
3) What are Mobile Web Apps?
Mobile spider web apps are spider web apps accessed using a mobile browser.
Note: Appium supports Safari on iOS in addition to Chrome or the built-in 'Browser' app on Android.
4) What are Hybrid Apps?
Hybrid apps conduct maintain a wrapper some a "webview" -- a native command that enables interaction amongst spider web content.
5) Which linguistic communication is used to write tests inwards Appium?
• We tin write our tests inwards whatsoever language, Since Appium is zip to a greater extent than than an HTTP server, a attempt out which needs to live on interfaced amongst Appium tin only role HTTP libraries to practise HTTP sessions.
• You exactly ask to know the Selenium protocol inwards enterprise to compose the correct commands in addition to that's it!
• Most mutual languages in addition to evolution frameworks are: C#.NET, Java, Ruby, Python in addition to Javascript.
6) What are the pre-requisite to role APPIUM?
Pre-requisite to role APPIUM is
• ANDROID SDK
• Eclipse IDE
• JDK
• Selenium Server JAR
• Webdriver Language Binding Library
• TestNG
• APPIUM for Windows
• APK App Info On Google Play
• js
7) What are the Advantages of Appium?
• Appium allows us to write tests against multiple mobile platforms using the same API.
• We tin write in addition to run our tests using whatsoever linguistic communication or attempt out framework.
• It is an open-source tool that nosotros tin easily contribute to.
• Provides cross-platform for Native in addition to Hybrid mobile automation.
• Support JSON wire protocol.
• It does non require recompilation of App.
• Support automation attempt out on physical device equally good equally similar or emulator both.
• It has no dependency on mobile device.
8) What are the limitations of Appium?
• Appium does non back upward testing of Android Version lower than 4.2
• Limited back upward for hybrid app testing. E.g., non possible to attempt out the switching activeness of application from the spider web app to native in addition to vice-versa.
• No back upward to run Appium Inspector on Microsoft Windows.
9) What attempt out frameworks are supported past times Appium?
• Appium does non back upward attempt out frameworks because in that place is no ask to back upward them.
• We tin role Appium amongst all attempt out frameworks nosotros want.
• NUnit in addition to .NET Unit Test Framework are exactly a few examples.
• We volition write our tests using i of the drivers for Appium; so our tests volition interface amongst Appium exactly inwards price of an external dependency.
10) What are the basic requirements to write Appium tests?
To write Appium tests nosotros require:
• Driver Client: Appium drives mobile applications equally though it were a user. Using a customer library you lot write your Appium tests which twine your attempt out steps in addition to sends to the Appium server over HTTP.
• Appium Session: You conduct maintain to get-go initialize a session, equally such Appium attempt out takes house inwards the session. Once the Automation is done for i session, it tin live on ended in addition to aspect for some other session
• Desired Capabilities: To initialize an Appium session you lot ask to define for sure parameters known equally “desired capabilities” similar PlatformName, PlatformVersion, Device Name in addition to so on. It specifies the variety of automation i requires from the Appium server.
• Driver Commands: You tin write your attempt out steps using a large in addition to expressive vocabulary of commands.
11) What is Appium Inspector?
• Similar to Selenium IDE tape in addition to Playback tool, Appium has an “Inspector” to tape in addition to playback.
• It records in addition to plays native application behaviour past times inspecting DOM in addition to generates the attempt out scripts inwards whatsoever desired language.
• However, Appium Inspector does non back upward Windows in addition to role UIAutomator viewer inwards its option.
12) How tin nosotros central information betwixt our attempt out in addition to the App nosotros are testing?
• Appium, genuinely the WebDriver specification, is non made for exchanging information amongst our app.
• Actually it is non impossible to central information amongst our app , soundless it volition require us to cook to a greater extent than layers of testability.
13) Explain the pattern of Appium?
• Appium is an “HTTP Server” written using Node.js platform in addition to drives iOS in addition to Android session using Webdriver JSON wire protocol.
• When Appium is downloaded in addition to installed, so a server is setup on our machine that exposes a REST API.
• Appium receives connecter in addition to command asking from the customer in addition to execute that command on mobile devices (Android / iOS).
• Appium responds dorsum amongst HTTP responses. Again, to execute this request, it uses the mobile attempt out automation frameworks to drive the user interface of the apps.
Mobile Test Automation Frameworks are:
Apple Instruments for iOS.
Google UIAutomator for Android API score sixteen or higher.
Selendroid for Android API score xv or less.
