What Are Important Factors To Consider When Testing A Mobile Application’s Security

As a mobile tester, a key area of your responsibility can be to test for both usability and security. How you answer this question can help a hiring manager understand how much knowledge you have about these two areas. When answering, it’s a good idea to reference two or three factors and describe why these are important.

Example:’I believe that two of the most important factors relating to security when testing mobile applications are encrypting and decrypting sensitive data. Using the right tools can help protect most sensitive information that may disrupt business and create uncertainty if someone outside the organisation accessed it. I explore ways to offer multi-user support, which helps ensure only authorised individuals can log in and make adjustments.’

What Is A Mobile Application

A mobile application, most commonly referred to as an app, is a type of application software designed to run on a mobile device, such as a smartphone or tablet computer. Mobile applications frequently serve to provide users with similar services to those accessed on PCs. Apps are generally small, individual software units with limited function. This use of software has been popularized by Apple Inc. and its App Store, which sells thousands of applications for the iPhone, iPad and iPod Touch.

A mobile application also may be known as an app, Web app, online app, iPhone app or smartphone app.

There are 3 types of apps:

Native apps live on the device and are accessed through icons on the device home screen. Native apps are installed through an application store . They are developed specifically for one platform, and can take full advantage of all the device features they can use the camera, the GPS, the accelerometer, the compass, the list of contacts, and so on. They can also incorporate gestures . And native apps can use the devices notification system and can work offline.

  • iOSon Objective-C or Swift
  • Hybrid appsfor all platforms altogether with Xamarin, React Native, Ionic, Angular Mobil
  • Hybrid apps are part native apps, part web apps. . Like native apps, they live in an app store and can take advantage of the many device features available. Like web apps, they rely on HTML being rendered in a browser, with the caveat that the browser is embedded within the app.

    What Is Test Planning

    Preparing to test mobile devices.

    Methods and tools continue to be developed to facilitate usability testing on phones and tablets. When planning a mobile device test, you should keep the following points in mind-

    • Your deadline and budget
    • The physical setup of the space and how you are going
    • Your target audience and device.

    Another important aspect after test planning is test equipment management.

    What Is The Difference Between Device Testing And Application Testing

    While device testing is typically being done to test mobile devices, mobile app testing will include testing an app that will be running on the selected device.

    When we call it instrument testing, hardware becomes a part of testing. In the case of mobile application testing, it depends, that is, if hardware integration is required for the application under test, then hardware testing will be involved.

    Automation is possible for mobile device testing as well as mobile application testing.

    What Is A Ui Test

    In this type of testing, we check the user experience to ensure that we provide an excellent experience to our users, mobile UI testing is highly recommended.

    It is your job as a tester to confirm that your application meets certain expectations, such as

    • Overall color scheme/theme of the device
    • Style and color of the mouse
    • The progress indicator on page loading
    • Menus and how they are implemented and are specific items
    • The overall response of applications on this device
    • Screen orientation / resolution.

    What Do You Mean By The Term Simulator

    Simulator is basically electronic equipment which is widely adopted in mobile application and other testing environments. It is also considered as a base station for the testing of an app for all its features and behavior before it is actually made available for public use on the concerned platforms. The apps are generally developed on simulators before the actual development takes place.

    What Are The Two Major Approaches To Test Automation

    Appium Interview Questions and Answers | Mobile Testing Interview Questions and Answers | Edureka

    There are two approaches to testing automation:

    Image-based approach This technique is based on processing the characteristics of images in Auto .

    It is easy to automate and can accurately test applications and rendering of GUIs.

    Object-based approach: It is a fast and accurate way to identify lists, buttons, and other objects in an application.

    This technique is much faster than an image-based approach and is compatible with many languages.

    How Would You Test For Recoverability

    Recoverability, or recovery testing verifies the application is able to recover after a crash or failure. All important data should be safe, with nothing lost during such crashes. It may require a lot of effort and resources to perform extensive recovery testing. These common examples are quite easy to perform for reproducing:

    • the loss of network during some critical action for an app that requires connection to the internet
    • low battery charge, device reboot due to the low charge
    • sudden interruption or closing of the app while critical processes or actions are still running in the app

    Why Is Mobile Testing Important For Businesses Today

    Testing is one of the most important parts of every software development process so, the mobile application is no exception. As the uses of mobiles are growing day by day, it gives rise to massive operation system fragmentation, screen sizes, and more. The QA teams must make a tremendous effort to ensure a seamless experience for users across various mobile devices without any functionality bugs and issues. The product team assigns a team of testers to test mobile applications through rigorous testing. This can help to enhance the app’s ratings and customer satisfaction for valuable referrals for even more downloads.

    What Are Some Common Bugs You May Find During The Mobile Testing Process

    This question also tests your technical ability to show that you can identify some common issues mobile testers typically face. Aim to talk about three to four bugs and provide a short overview of each to demonstrate your knowledge. You can cover more than four to highlight your expertise if there’s time.

    Example:’Generally, the most frequently found bugs fall into four different types: critical, block, major and minor. Critical bugs relate to when a device’s operating system crashes during testing of an application. Block bugs are when the device is unresponsive, even when the device status is on. Major bugs relate to a specific feature of an application that cannot perform correctly. Finally, a minor bug typically relates to an issue with the graphic user interface.’

    What Does Defect Removal Efficiency Mean In Software Testing

    Showcasing Flight Centre

    Defect removal efficiency is one of the testing metrics. It is an indicator of the efficiency of the development team to fix issues before the release.

    It gets measured as the ratio of defects fixed to total the number of issues discovered.

    For example, lets say, there were 75 defects discovered during the test cycle while 62 of them got fixed by the development team at the time of measurement. The DRE would be 62/75 = 82.6%

    Question 2 Explain The Difference Between Simulator And 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.

    Ideally, you should be able to look into the simulation and observe properties that you would also see if you looked into the original target. In practice, there are some shortcuts to the simulation for performance reasons that is, some internal aspects of the simulation may actually be an emulation.

    Can Penetration Testing Be Done On Mobile Applications

    The simple answer to this question is Yes!

    Penetration testing is required while testing mobile applications because mobile applications are also prone to attacks from fraudulent hackers. A mobile application tester with penetration testing skills is highly recommended. He/ she will serve as an ethical hacker to find out how easy or difficult it is to gain unauthorized access into the application.

    Thus, security loopholes and unforeseen data leaks are promptly attended to. A penetration test and a general security test will ensure that all the data associated with the application are secure. Thus end-users feel comfortable using the application.

    What Do You Understand With The Term Robo

    It is not always easy to perform the test on the Android Framework for the device. This is because it takes a lot of time, as well as efforts to build different test cases and developing the strategies. Thus, the Robo-electric approach simply lets the users run the Android test without depending o a simulator.

    What Is Static Testing When Does It Start And What Does It Cover

    Mobile Testing Interview Questions and Answers | Mobile Application Testing

    Static testing is a white-box testing technique that directs developers to verify their code with the help of a checklist to find errors in it. Developers can start the static testing without actually finalizing the application or program. Static testing is more cost-effective than dynamic testing as it more areas than dynamic testing in a shorter time.
