Advantages of System Stability Test And How To Do It

How to Do System Stability Test

  • To determine the scope and objective of the testing, we must ensure that the application server does not crash during the load test executions.
  • Determine the business issues, verify the system performance, and load as per the end-user perspective.
  • Assign the different responsibilities and roles like; creating test plan, test case design, test case review, test execution, etc.
  • Ensure the test deliverables within the specified time
  • Ensure proper load testing tools and experience team is present for the same.
  • Measure the risk and cost involved in the testing. This will determine the cost of each execution in terms of CPU utilization and memory.
  • Determine the defect tracking and reporting and their proper mapping with the requirements

What Happens If We Don’t Do Stability Test?

  • If stability testing is not carried out, the system slows down with a large amount of data.
  • Without stability testing, the system crashes suddenly.
  • In absence of stability testing, the system’s behavior is abnormal when it goes to a different environment.
  • In absence of stability testing, the system’s performance decreases which in turn can have bad effects on the business.

Advantages of Stability Testing

  • It gives the limit of the data that a system can handle practically.
  • It provides confidence in the performance of the system.
  • It determines the stability and robustness of the system under load.
  • Stability testing leads to a better end-user experience.

Why Is Performance Testing Needed?

Experts believe that mobile application errors are much higher than what has 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
  • Frequent timeouts
  • Stalling and freezing
  • Failed uploads

Poor application experience means frustrated customers, which translates into lost revenues. Research shows that over 47% of the respondents, when faced with a broken image would exit the application and transact on a different platform.

Application speed changes as per region. 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 at various speeds and on different networks. Some countries have 2G connections, 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 developed nations like the US, the UK, Germany, Japan, and so on. However, the same app is very slow in developing countries like China, India, Brazil, and Southeast Asia.

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 the high speed, scalability, and stability of the system are achieved by the system under high demand.


Many applications are improperly designed and do not release the device memory after usage. This will gradually lead to memory loss. We can overcome this issue with stability testing. So, stability testing is very important. It is a type of non-functional testing, therefore it is only concerned with the characteristic of the application.
