The last few years have been revolutionary for mobile devices. The mobile device was transformed from a simple reutilized operation device to a more complicated and sophisticated one. Mobile applications become extraordinary when adopted by individuals and organizations to organize and manage almost every single life activity. Mobile devices are a necessity in our lives due to attributes like ubiquity which means availability anywhere at any time, convenience, instant connectivity, personalization, and location-based services. Mobile applications become so popular and available in different types and for different purposes. With the fact that more than one billion smartphones were sold and 6.8 billion mobile subscriptions worldwide in 2013, more than 300,000 applications have been developed, and a prediction of 76.9 billion global downloads in 2014, the importance of testing these applications is surfaced for both privacy and security purposes. The mobile application landscape is continuously growing and highly dynamic. The widespread availability of mobile devices combined with the declining prices and increased functionalities make them more powerful than a PC. The handset culture and improvement of bandwidth, and other factors together encourage the new operating system versions releasing and various types of mobile applications developing. Testing mobile applications is an expensive, time-consuming, and complex process, but it is still required and needed to guarantee consumer’s satisfaction every time they use the mobile applications. It’s vital to make sure to test the application by specialist and experienced testers not just to find errors but also to critique the quality of mobile applications before release it in the market to avoid exploring problems by consumers who could simply never use the application again, and you may never hear a word from them. Testing mobile applications are essential to ensure the usability, mobility, and security of the applications. One of the main challenges of testing mobile is the high cost and availability of devices. More and more companies rely on emulators in the early stages of development.
Important Mobile Application Test Techniques and Tools
We read a lot of thesis on mobile application testing and found many methods and tools for mobile application testing. The following are the conclusions mentioned in the project.
Usability testing is a user-based technology that uses products to find product defects and improve user experience quality. This is a very important test in mobile app testing. Usability testing is also one of the important criteria for judging software quality. Usability testing is a big test direction, it requires testers to understand the product well and maintain creative thinking. Testers need to be patient and listen to the user’s advice and have a good ability to find problems in order to make the product closer to the user’s needs and enhance the user experience. Panagiotis T. Koziokas et al. conducted a controlled experiment and study on the usability test of mobile apps.
Quality-of-service testing(QoS testing)
Quality of service(QoS) is the quality that a service provider can provide to its customers. In mobile applications, the performance, reliability, and availability of telecom services are mainly reflected. In mobile applications, the impact of the network on the application is more obvious than in traditional applications. Poor mobile networks, the irrational allocation of applications to network resources can greatly affect the user experience. The improvement of QoS testing is very important for mobile applications.
Analytical Studies of the Resource Utilization of the Resources
1. Application performance during its 1 st cycle (Starting of the Activity)
This is the profiler status when the application is very first launched. We can see that the resource utilization graph is showing ups-downs based on the amount of CPU, mobile bandwidth, network is being utilized at that instance.
2. Performance during the transition between pause and resume phase
This is the phase occurred when we pause our application (this is the phase when our application runs in the background phase) and beings the execution again from paused state to running state. In this context switching, the application at first utilizes a high spike of resources, then stabilizes itself thus resulting in less resource utilization thereafter.
3. Memory analysis
The memory requirement for fully functioning software is very low, but the cost to store its data is quite significant in the form of SSD or hard drive.
4. CPU Utilization
Throughout the testing, we came to the conclusion that small mobile applications use very less proportion of CPU throughout their life-cycle. Since our mobile application seems to use very minimal resources, so we can say that users will be experiencing very smooth running of this software on their hardware device.
5. Network Utilization
As the aim of the project was to build the software which will be very efficient in networking, so while testing the networking and bandwidth utilization of the software, we can conclude that the software uses very minimal bandwidth to transfer the data. In fact, it stores all the users’ information locally, so in this case, no network connectivity is required or we can say that software can run in offline mode.
6. Energy Utilization
The small mobile application utilizes a very less proportion of energy for their functioning. From the CPU utilization chart, we can say that mobile application fully utilizes the CPU time, hence they dissipate less energy. This implies its throughput is high. If the throughput will be high, we can say that the mobile application is not lagging. Thus this will maintain the temperature of the device in which it will be running.
After conducting a well-formed analysis and research on the working stages of the software on the Android operating system platform, it can be easily said that the software that works in the offline mode need not require much resource utilization. The resource utilization of the android application is very affordable and eco-friendly. This prevents the overuse of the resource and prevents the heating of the device. After the study of the android applications on the offline mode of working, we can say that there will not be much of the performance difference as compared to that of the on-line working mode application. There will only be a difference in the network utilization of the software. A developer should be very well aware of the kind of application he is going to build. Based on the requirements he should constrain the application resource utilization so as to make the application run efficiently and without lagging. This profiler helps developers to build their applications with enhanced user experience.
