26 points that must be paid attention to for stability test

1. Test the software many times , Long run , Is it working .

2. Open and close the software for a long time, and check whether the software and system are normal .

3. Whether the software switches to different business operations after executing a business for a long time is affected .

4. The software starts for a long time but does not perform any operation , Then check whether the business operation can be performed normally .

5. The software operates the daily number of users for a long time , Observe whether the system memory utilization is increasing , Whether the available memory is reduced , Whether the memory overflows , Whether the saturated operation memory is too large 、 Overflow or not .

6. The software starts for a long time and runs normally , The observation system CPU Whether the utilization rate is getting higher and higher , During saturation operation , The observation system cup Usage rate , At the end of the saturation operation ,CPU Whether the utilization rate can return to normal .

7. During the operation of the system , Apply pressure to system saturation , Observe various performance indexes of the system , And server metrics 、 Observe whether the server power supply voltage decreases 、 The case 、 Memory 、 Hard disk 、CPU And other hardware indicators to observe the stability of the system .

8. Simulate normal pressure , Simulate the actual daily number of users for operation . To save 、 take 、 build 、 Check data , Verify whether the database reads and writes normally .

9. Simulated saturation pressure test , Simulate the daily maximum number of users in practice . To save 、 take 、 build 、 Check data , Verify whether the database reads and writes normally , Whether the system operation is affected .

10. Multiple associated software , There are interfaces to access data exchange , Close one of the software , Check whether the software runs stably .

11. Whether the simultaneous operation of multiple pairs of different functional module software can respond normally , Whether the database is running normally .

12. For software running on the network , Use network tools to minimize the bandwidth of the software , Check whether the system processing is normal .

13. For software running on the network , Network disconnection during service execution , Check whether the system processing is normal , The software can run normally .

14. Software with database operation , If the database stops running , Check whether the program can handle .

15. Whether the simultaneous operation of different functional module software can respond normally .

16. For different operating systems, it is mainly windows Series operations , such as XP,WIN7 etc. , Check whether different operating systems can operate stably 、 Report errors .

17. Whether the software can start normally after the system is powered off 、 The normal operation , Or give an exception prompt .

18. Multiple associated software , There are interfaces to access data exchange , Close one of the software , Check whether the software runs stably .

19. Whether the stability of the original function is affected after the version upgrade , Whether there are exceptions in the original data operation .

20. Whether the normal operation of the whole software is affected after the abnormality of a unit module of the software .

21. When the system crashes , Whether the hoisting system software can operate normally .

22. Analysis system operation , Which businesses or functions have a large amount of data processing , If there is , These functions or businesses should be handled repeatedly , Check whether the system can operate normally , And observe the performance and resource utilization of the system .

23. Analysis system operation , Which businesses or functions have a large amount of data output or generation , If there is , These functions or businesses should be handled repeatedly , Check whether the system can operate normally , And observe the performance of the system and the occupation of hard disk .

24. If the system allows multiple different client versions to access the server at the same time , Build as many different versions of the client as possible , Perform a large number of operations to access the server , See if there will be data conflicts or exceptions .

25. Confirm with developers or designers , Which businesses or functions of the system are in the process of processing , It takes up a lot of memory ,（ For example, batch generation of large capacity files , Batch instantiation object , Batch generation of connections, etc ）, These operations need to be repeated a lot , Check the system for memory leaks .

26. If load balancing is used in the system structure , Then the load balancing strategy should be considered , To simulate a large number of users for various concurrent operations , Check whether load balancing works effectively .
