Introduction to Mobile Application Testing Interview Questions and Answers
Mobile application testing is the process of testing the software, which is developed for mobile devices. This testing is based on functionality, performance, user-friendly, UI, etc. These can be tested with the help of manual testing or automation testing. Mobile application testing is really challenging sometimes as it requires a lot of groundwork and how to test the mobile app is a difficult task to decide. There are many challenges in testing mobile applications.
Now, if you are looking for a job that is related to the Mobile application testing then you need to prepare for the 2023 Mobile application testing Interview Questions. It is true that every interview is different as per the different job profiles. Here, we have prepared the important Mobile application testing Interview Questions and Answers which will help you get success in your interview.
These top interview questions are divided into two parts are as follows:
Part 1 –Mobile Application Testing Interview Questions (Basic)
This first part covers the basic Interview Questions and Answers.
Q1. What are the different types of testing for Mobile applications?
The types of testing are functional testing, laboratory testing, performance testing, interrupt testing, usability testing, memory leakage testing, installation testing, certification testing, security testing, location testing, Black box testing, crowdsource testing, load testing.
Q2. Explain the challenges while testing Mobile applications?
This is the common Mobile application testing Interview Questions asked in an interview. The few challenges for testing the mobile applications are like scripting, compatibility, Device availability, an application must be downloadable generally from an app store, a variety of mobile devices, application to pick the call, mobile network operators, the way of testing.
Q3. Explain the types of Mobile applications?
There are different types of applications that are Web applications, hybrid applications, and native applications. Web applications are used to run from mobile browsers like chrome, firefox, opera, safari, etc. These applications start with ‘m’. Hybrid applications are a combination of native and web applications. These applications can run on any device. It can be used offline as well and these are developed using the web technologies that are HTML5 and CSS. Native applications that can be installed on a device from the play store of Android and app store of apple example what’s app.
Q4. What is the difference between the emulator and simulator?
An emulator is a software, which is used to test mobile applications without the handset. A simulator is referred to as electronic network simulation equipment for mobile phones and it helps in connecting networks without roaming service and can make voice calls, data and SMS.
Q5. Explain the bugs that are mainly found in Mobile testing?
The bugs are critical, major, minor and block. The critical bug is the one when the phone system crashes while testing the particular feature in the mobile handset. A major issue is the one when the particular feature not able to perform its functions as expected. A minor issue is like the interface is not as required or like some label or button not at its place. Block bug means while performing any functionality, the phone hangs up or not able to do anything on the device and need to reboot the device only.
Part 2 – Mobile Application Testing Interview Questions (Advanced)
Let us now have a look at the advanced Interview Questions.
Q6. On what basis the testing automation tool would be used to test the mobile app on the device?
To do mobile testing with automation tool and that tool should have the following things:
- Multi-platform support: The automation tool should support multiple platforms. It means the current platform as well as future target frameworks or platforms.
- OS version: The tool should be able to support the different Operating systems like IOS, Android, or any other version.
- Scripting: What type of script it will support and mainly object-based tools provide the high degree of script usability.
- Jailbreak: When the tool uses the rooted device because of which it may not support the latest version of the operating system.
- Source code: Sharing source code is not possible always whenever the changes were done to the source code.
Q7. What are the advantages of automation testing?
The advantages of automation testing in regression testing. It helps in saving time as in regression testing, a lot of test cases need to be done again and again. So, automation testing will run the scripts to test the same functionality again and again. Load and performance testing can be done through or the best possible way as it requires simulation of thousands of concurrent users and devices, which can be possible through tools only. These tools are like load runner. Complex tests have multiple components that need to be tested at once. The other main advantage is availability. The test cases can be run any time as per the requirement. The same thing can be reused means tests or scripts can be used for other devices or applications as well. The most important is reliability as it is performed with help of tools or the scripts. In Manual testing, there can be issues due to human error but it is not possible in automation testing. Test automation has become an integral part of mobile application development.
Let us move to the next Mobile application testing Interview Questions.
Q8. What can be considered to test mobile app development through black box technique?
The following things should be considered:
- Applications should be tested on multiple devices or different mobile handsets.
- Mobile applications should be tested with help of changing ports and IP addresses. So that it can be tested whether it is getting connected and disconnected properly.
- Testing the functionality and making calls or messages to other devices.
- Testing the mobile application through different browsers like chrome, firefox, opera, and safari etc.
- Testing on different devices like downloading the mobile application and installing on the particular device and uninstallation as well.
- Compatibility testing e.g. attaching the photo or other attachments.
- Functional testing, interrupt testing, application performance testing, and other negative testing entering invalid credentials and other behavior of an application.
Q9. What is the difference between priority and severity?
This is the popular Mobile application testing Interview Questions asked in an interview. Priority refers that how important functionality is and needs to be fixed earlier or later. Severity refers to the consequence of bug or issue in the application means how serious that issue is. Priority is being termed in the following sequence P1, P2, P3, P4, and P5. P1 is referred to as Critical, P2 is medium, and P3 is Low and so on. Severity is termed as Sev5, Sev4, Sev3 and so on. Sev5 is the highest one.
Q10. What are the different tools that are used for Mobile application testing?
These different tools are Appium, selenium, Robotium, JMeter, Load runner and other tools for tracking like JIRA, Bugzilla, Rally and HP QC etc.
