Mobile application testing focuses on testing the functionality and features of mobile applications. It is performed by application vendors. Mobile testing focuses on testing the native features of mobile devices like calls, SMS, Bluetooth, etc. It is performed by handset makers. A simulator mimics the outward behavior of a target but not its internal state, while a simulation accurately models both the outward behavior and underlying internal state of a target. Types of mobile application testing include usability, compatibility, interface, services, low-level resource, performance, and operational testing. The general structure of a mobile testing framework includes application packages, instrumentation, test runners, and test packages. Common bugs in mobile applications include critical bugs, block bugs, major bugs, and minor
Appium Interview Questions and Answers | Edureka
- 2. What Is Mobile Application Testing And How Is It Different From Mobile Testing? www.edureka.co
- 3. Mobile Application Testing vs Mobile Testing www.edureka.co Mobile Application Testing Mobile Testing Focus on functionality and features of applications Focus on native applications features like call, sms, bluetooth etc Performed by applications vendors Performed by handset makers
- 4. Explain the differences between a simulator and an emulator www.edureka.co
- 5. Simulator vs Emulator www.edureka.co Simulator Emulator Emulation is the process of mimicking the outwardly observable behavior to match an existing target. The internal state of the emulation mechanism does not have to accurately reflect the internal state of the target which it is emulating. Simulation, on the other hand, involves modeling the underlying state of the target. The end result of a good simulation is that the simulation model will emulate the target which it is simulating.

- 17. www.edureka.co Native Native apps are developed specifically for one platform, which is coded with a specific programming language (like Objective C for iOS, Java for Android) and installed directly onto the device and can take full advantage of all the device features — they can use the camera, the GPS, the accelerometer, the compass, the phone book etc.
- 18. www.edureka.co Native Web Web applications are mobile web portals that are designed, customized and hosted specifically for mobiles. They are accessed through the mobile device’s web browser using a URL.

- 19. www.edureka.co Native Web Hybrid Hybrid Apps are Web apps embedded in a native app, run on the device, and are written with web technologies (HTML5, CSS and JavaScript). Hybrid apps run inside a native container and leverage the device’s browser engine (but not the browser) to render the HTML and process the JavaScript locally.

- 110. Open Source vs Vendor vs Inhouse Open Source Vendor Inhouse Open source tools are free to use frameworks and applications. Engineers build the tool, and have the source code available for free on the internet for other engineers to use. Vendor tools are developed by companies that come with licenses to use, and often cost money. Because they are developed by an outside source, technical support is often available for use. An in-house tool is a tool that a company builds for their own use, rather than purchasing vendor tools or using open source tools.
