Performance testing: use automated testing tools to simulate the testing of system performance indicators under normal, peak and abnormal conditions.

Features:

After functional testing

A design process that requires test plans, test scenarios, and test cases

The performance test environment should be consistent with the real environment as much as possible

The key and difficult points are the design of the early data and the analysis of the later data.

Performance test cases are designed based on system architecture and have high reusability.

Classification:

General performance testing: the main verification software in the normal environment and system conditions, that is, without any pressure, repeatedly run the software to verify whether it can meet the performance indicators, such as response time, resource utilization (initial, benchmark test)

Load testing: verify the load when a predetermined threshold is reached. Based on or simulating the real operating environment of the system and the real business usage scenarios of the users, constantly put pressure on the system or extend the running time of the system under certain pressure to verify the changes of the performance indicators of the system. Until there is an inflection point (that is, an index reaches a pre-agreed threshold)

Stress test: when the simulation system has been in the limit load or some performance index has been saturated, continue to increase the load or running time to the system, observe the performance of the system, and verify whether there are memory leaks, downtime and so on.

Large data volume test: refers to the use of a large amount of data to cause pressure or impact on the system to verify whether the indicators of the system are running properly (the storage device of the system itself has a large amount of data; a large amount of data created dynamically during concurrency or an operation)

Configuration testing: testing under different software and hardware configurations of the system to verify the optimal allocation principle of resources in the system

Stability test: mainly refers to the continuous operation of the tested system to check the stability of the system. (the stability of the system is measured by MTBF (the average time interval between errors). The larger the MTBF, the stronger the stability of the system. )
