Here are some of the reasons why performance testing is important:
1. Experts believe that mobile application errors are much higher than what have been reported. Mobile applications struggle with network issues, especially when the server is congested. And if the applications are running on unreliable mobile networks, it becomes even more difficult. Some of the problems that apps face in such a situation are:
Issues in downloading images or broken images.
Giant black holes in content feeds
Booking or checkout errors
Stalling and Freezing
2. Poor application experience means frustrated customers, which translates into lost revenues. A research shows that over 47% of the respondents, when faced with a broken image would exit the application and transact on a different platform.
3. Application speed changes as per regions. It is important to update an app country-wise and test it for the same. Internal testing should be done on the performance of the applications in various speeds and different networks. Some countries have 2G connection, some have 3G and others 4G. It is important to check whether users of the application across the world can use it conveniently, without any network issues. There are high chances of the app functioning at an optimal level in the developed nations like US, UK, Germany, Japan, and so on. However, the same app is very slow in developing countries like China, India, Brazil and Southeast Asia.
4. Moreover, a system may run conveniently with only 1,000 concurrent users, but it might behave randomly if the user base increases to 10,000. Performance testing determines whether high speed, scalability, and stability of the system is achieved by the system under high demand.
While there are different tools to test the above-mentioned criteria, there are different processes that determine whether the system is functioning according to the set benchmark. It is also important to plan the way performance testing should be done.
