For those preparing to face mobile testing interview questions when applying for a QA job, this list of contents below will set the stage to get you in the groove. Mobile application testing means a process in which an application developed for handheld mobile devices is tested to ensure its functionality, usability, and consistency.

Testers can perform mobile application testing manually or with automation. Testing is an indispensable part of every software development process. Mobile application is no exception: the growing number of mobile devices gives rise to a massive operation system fragmentation, screen sizes, and more. This process aims to test features, i. It also consists of factory testing and certification testing.

Alternatively, mobile application testing means testing the mobile application on different mobile devices to ensure its consistency and functionality. A standard Android strategy can include these testing types: unit testing, system testing, integration testing, and operation testing subject to the features available of the tested mobile application.

A comprehensive test strategy should be planned based on specific guidelines to secure an effective performance of a new mobile application. Here are some of the essential points:.

Similar to the plan of other application under tests, a plan designed for automated mobile application testing should include:. In an end-to-end mobile testing process, QA teams test the entire application from beginning to end to ensure its flow behaves as expected. Throughout these steps, there are some of the many critical requirements to consider:. Both Emulators and Simulators are virtual devices that are not real phones but have the same functionality as real handsets.

The following table shows the significant difference between a simulator and an emulator:. These are an advanced tool that records historical information about processes running on your device. Although 2G is a slower network, it is better to test on a slower network in order to track the application performance. Using emulators is the most effective way in case there are many different screen sizes of devices to test. Additionally, some other kinds of bugs are also found during the mobile application testing process, for example:.

Here are some of the critical points:. Check out this article to choose the right Automation Test Cases. Executing mobile testing in Cloud Computing poses various challenges for both beginners and advanced testers.

One of the most standard testing frameworks for Android applications is the Android testing framework. It is comprised of three segments:. Testing applying the Android Testing framework with a device or an emulator is challenging. And the Robolectric testing framework is considered as a solution to address this challenge. This changes quite often, so please check the Apple site for the most recent info. The latest version of Android is The initial version of Android This changes quite often, so please check the Android site for the most recent info.

Each ipa file includes a binary and can only be installed on an iOS device. When choosing the most appropriate test automation tool , in addition to affordability, it is essential to consider the following technical criteria:. For mobile testing, there are two types of automation testing tools: object-based or image-based tools.

Mobile testing interview questions can be unlimited regarding the number of items and areas covered. Even though the above answers may not comprehensively be applied in your interview, we hope that those will help you ace a job and grow yourself in the mobile testing journey. Should you have any suggestions on this list of interview questions, please feel free to add it here.

It is the amount of code concealed via automated tests. If the team achieves the intended level of code coverage CC ratio, then it can choose to end the validation. This unit of measurement includes only operational time between failures and does not include repair times, assuming the item is repaired and begins functioning again.

MTBF figures are often used to project how likely a single unit is to fail within a certain period of time. In software testing, verification is a process to confirm that product development is taking place as per the specifications and using the standard development procedures. The process comprises the following activities:. 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. It is a standard software testing approach that requires testers to assess the functionality of the software as per the business requirements. A test plan stores all possible testing activities to ensure a quality product.

It gathers data from the product description, requirement, and use case documents. Test coverage is a quality metric to represent the amount in percentage of testing completed for a product. It is relevant for both functional and non-functional testing activities. This metric is used to add missing test cases. But you can follow the below steps to come closer. Many times, it is the developers who test individual units or modules to check if they are working correctly.

Whereas, integration testing validates how well two or more units of software interact with each other. System testing should start only if all modules are in place and they work correctly. However, it should be performed before UAT user acceptance testing. The test driver is a section of code that calls a software component under test. It is useful in testing that follows the bottom-up approach. The test stub is a dummy program that integrates with an application to complete its functionality.

It is relevant for testing that uses the top-down approach. It is favorable as it does not require the development team to complete coding for starting QA. Instead, both coding and testing go hand in hand. However, it may require continuous customer interaction. Data flow testing emphasizes for designing test cases that cover control flow paths around variable definitions and their uses in the modules. It expects test cases to have the following attributes:.

End-to-end testing is a testing strategy to execute tests that cover every possible flow of an application from its start to finish. The objective of performing end-to-end tests is to discover software dependencies and to assert that the correct input is getting passed between various software modules and sub-systems.

If the required specifications are not available for a product, then a test plan can be created based on the assumptions made about the product. But we should get all assumptions well-documented in the test plan. It is suggested to perform a regression testing and run tests for all the other modules as well. Finally, the QA should also carry out a system testing. If the standard documents like System Requirement Specification or Feature Description Document are not available, then QAs may have to rely on the following references, if available.

Another reliable way is to have discussions with the developer and the business analyst. It helps in solving the doubts, and it opens a channel for bringing clarity on the requirements. Also, the emails exchanged could be useful as a testing reference. Smoke testing is yet another option that would help verify the main functionality of the application.

It would reveal some very basic bugs in the application. If none of these work, then we can just test the application from our previous experiences.
