During performance testing, an application is evaluated on how well it performs and behaves under various loads. In this test, the application is continuously and steadily loaded until it reaches a threshold point (a point beyond which the application cannot withstand the load). This ENSURES that the application performs as expected under certain conditions like when large numbers of users access it or when a key infrastructure component such as a database server is eliminated. The most COMMON scenarios in performance testing include: 

• Test the application under various load conditions to determine if it performs as expected.
• Check the current network coverage for its ability to support maximum, average, and minimum user levels.
• Ensure that client-server configurations provide optimal levels of performance.
• Identify the application and infrastructure bottlenecks that affect the app's performance.
• Analyze whether the hardware and/or product can cope with the projected load volumes.
• Evaluation of the battery life's ability to support the expected load volumes.
• Check the performance of the application when it's switched from a 2G/3G network to WIFI or vice versa.
• Make sure that battery consumption, memory leakage, GPS, and camera performance are within permissible limits.
• Validate the app's endurance whenever there is a high user load.

The global digital transformation is leading to a rapid increase in mobile usage. Everyday life is inextricably linked to our mobile phones; life without one is difficult to imagine. With consumer demand increasing, nearly all software applications now have mobile applications, so businesses have to put more emphasis on mobile testing. Due to the demand for innovative mobile solutions delivered quickly, the need for mobile testers has grown greatly over the years. In light of the rapidly expanding mobile industry, there are MANY opportunities in mobile testing. This blog includes basic and advanced mobile testing interview questions and answers for both FRESHERS and experienced mobile testers. This set of questions covers all the basics of mobile testing and demonstrates your familiarity with the topic.

Mobile Functional Testing means testing the functions of mobile applications, such as user interactions and transactions. Functional testing is performed by mobile application developers to ensure application quality, meet user expectations, and reduce the risk of errors in mobile applications. The most common scenarios in functional testing include: 

• Verify that all required MANDATORY fields WORK as intended.
• Every time an application starts/stops, make sure the application works correctly.
• If the app is running, check whether SMS can be stored, processed, and received.
• Check if the device can perform multitasking functions when necessary while the application is running.
• Verify that the application provides access to social network features, such as sharing, posting, and NAVIGATION.
• Check that the application is CONFIGURED to support the PAGE scrolling scenarios.
• Verify that navigation between relevant modules is in accordance with the requirements.
• Check to ensure that the user receives an appropriate error message, such as "Network error".
• Ensure that the installed application does not consume the memory of other applications and that it enables other applications to perform satisfactorily.
• If the system crashes or the application crashes, verify that it resumes from the last operation.
• Ensure that the user has access to the required resources to install the application smoothly and that it will not lead to significant errors.
• Testing the performance of the application in all versions of Mobile, including 2G, 3G, and 4G.

Some of the top mobile application TESTING scenarios include: 

• Install and launch the application before USING it.
• Ensure that the application is adaptable to the SCREEN of the mobile device and that all menus on the app are working.
• Inspect the readability and clarity of the text in the app.
• Check if the display of the application can be adjusted to various display modes (landscape/portrait).
• Be sure that the application does not interfere with other applications on the device.
• Ensure the back key on the play screen will take you back to the application's start-up screen.
• When the device is resumed from inactive mode or the lock screen, make sure the application still functions as intended.
• Applications should remind users to save any changes they make to settings before moving on to other activities.
• As soon as the user attempts to enter text, the on-screen keyboard should appear.
• Check that the application functions as intended when the "battery low" notification appears.
• Check how the application performs over the various internet network TYPES, such as 1G, 2G, 3G, and 4G.
• Applications should be adaptable to different mobile platforms or operating systems, including Android, iOS, Microsoft, etc.
• See how the application behaves at different levels of battery and temperature, and many more.

ONE of the most challenging aspects of app testing is writing test scenarios for mobile applications. However, scenario-based testing is the BEST method for testing complicated systems, so be sure to keep these tips in mind when preparing mobile application testing scenarios.  

• Examine the Requirement Document, including the BRS (Business Requirement Specification), SRS (Software Requirement Specification), as well as the FRS (Functional Requirement Specification) pertaining to the SUT (System Under Test). 
• Design simple test scenarios rather than complex ones. Keep them concise and simple, so they are easy to understand. 
• Generate test scenarios that cover all possible features of the target application. Users and business flows involved in the operation of the application/website must be covered by these scenarios. 
• Put an EMPHASIS on project METHODOLOGY. 
• Identify the priorities of your customers and devise test scenarios accordingly. 
• Keep an eye on the expected outcome. 

Test scenarios are simple sets of functionalities (DETAILED documents of test cases) that can be automated or manually tested in a mobile application or website. In addition to providing INSIGHT into the positive and negative CHARACTERISTICS of an application or website, test scenarios are often very useful to the testing team.  Because testers test applications from the user's perspective, they must put themselves in the position of the user during a test SCENARIO. 

Advantages:

• Help developers understand how mobile applications really work
• Ensure that the end-to-end functionality of the app under test works as expected.
• The testing team will be able to understand what needs to be tested with the AID of an effective test scenario.
