4) List out the types of mobile app testing?

The types of mobile app testing includes

    Usability testing
    Compatibility testing
    Interface testing
    Services testing
    Low-level resource testing
    Performance testing
    Operational testing
    Installation tests
    Security testing

5) Mention what is the Android testing strategy?

The standard Android testing strategy must include the following test

    Unit Test
    Integration Test
    Operation Test
    System Test

6) Explain Android testing framework?

Android testing framework includes three segments

    Application Package: It is the target application that requires to be tested
    Instrumentation TestRunner: It is a test case runner that runs test cases on target application. It includes an SDK tools for building test and a tool that provides APIs for writing program that control an android device, for example, MonkeyRunner
    Test Package: It includes two classes, Test case classes, and Mock objects. Test case classes include test methods to perform on target application, while mock object includes mock data that will be used as sample input for test cases.

7) List out the best practices for Android Testing?

    Developer should prepare the test cases at the same time when they are writing the code
    Together with source code all test cases should be stored
    Use continuous integration and execute tests every time the code is changed
    Avoid using rooted devices and emulators

8) Mention what are the common bugs found while mobile testing?

    Critical: Your phone system crash when testing particular feature in your device
    Block: Unable to do anything though phone is on unless you reboot your device
    Major: Unable to perform a function of a particular feature
    Minor: Under minor bugs usually GUI bugs fall.

9) Explain what is Robo-electric testing framework?

Testing done on Android Testing Framework for emulators or device is difficult.  Running and building test case sometimes takes lots of development effort.  Robo-electric framework allows you to run Android test directly on JVM without the need of a device or an emulator.

10) Explain how A/B testing is done for ios app?

A/B testing for ios includes three steps

    Configure a test: It prepares two versions of your iOS app (A&B) and test metric

    Analyze: It select and measure better version to release

11) While performing end to end mobile testing what are the major criteria, you have to take in consideration?

    Installation
    Application launching without having network
    Uninstallation of app
    Orientation of app if it supports
    Testing application performance on a different kind of devices and network scenarios

    Script Usability: Object-based tools provides a high degree of the script usability
    Jailbreak Requirement: If the tool uses rooted devices, it may not support latest OS version and may be incompatible with MDM policies
    Source Code Changes: Sharing source code may not be possible always
    Lead time for New OS version: How soon tool can support new iOS/android/other OS version

14) When to choose automation testing and when manual testing?

Manual Testing

    If the application has new functionality
    If the application requires testing once or twice

Automate Testing

    If the regression tests are repeated
    Testing app for complex scenarios
