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.
