Performance test classification

The performance test method is to simulate the combination of business pressure and usage scenarios of production operation , Test whether the performance of the system meets the production performance requirements . In layman's terms , This method is to verify the capability status of the system under specific operating conditions . in other words , This method is the premise of understanding the system performance , And have a clear goal for the demand , And carried out in a determined environment .

The load test

By continuously pressurizing the system under test , Until the performance index reaches the limit , for example “ response time ” Exceeding a predetermined target or a resource has reached saturation .

characteristic ：

1、 The main purpose of this performance testing method is to find the limit of the system's processing power .
2、 This kind of performance test method needs to be carried out in a given test environment , Usually, we also need to consider the business pressure and typical scenarios of the system under test 、 Make the test results have business significance .
3、 This performance test method is generally used to understand the performance capacity of the system , Or with performance tuning .
in other words , This method is to pressurize a system continuously , See when you've exceeded “ My request ” Or system crash .

 

Pressure test （ Strength test ）

The pressure test method is used to test the system in a certain saturation state , for example cpu、 Memory is saturated , The conversational capability that the system can handle , And whether there will be errors in the system

characteristic ：

1、 The main purpose of this performance test method is to check the performance of the system under pressure , Application performance .
2、 This kind of performance test is usually carried out by means of load simulation , So that the use of system resources to a higher level .
3、 This performance test method is generally used to test the stability of the system .

in other words , This kind of testing puts the system under a lot of pressure , See if the system is stable , Where's going to go wrong .

 

Concurrent test

The concurrency test method simulates the concurrent access of users , Test multi-user concurrent access to the same application 、 Whether there is deadlock or other performance problems in the same module or data recording .

characteristic ：

1、 The main purpose of this performance testing method is to find the problems of concurrent access that may be hidden in the system .
2、 This performance testing method mainly focuses on the concurrency problems that may exist in the system , For example, memory leaks in the system 、 Thread lock and resource contention .
3、 This performance testing method can be used in all stages of development, and needs the cooperation and support of relevant testing tools .

in other words , This kind of testing focuses on multiple users at the same time （ Concurrent ） Pressurize a module or operation .

 

Configuration testing

Configure the test method through the soft test of the system under test \ Adjustment of hardware environment , Understand the extent to which different influences on system performance , So as to find the optimal allocation principle of system resources .

characteristic ：

1、 The main purpose of this performance testing method is to understand the influence of various factors on the system performance , So as to determine the most worthwhile tuning operation .
2、 This kind of performance test method is usually carried out after having a preliminary understanding of the system performance .
3、 This performance testing method is generally used for performance tuning and planning capabilities .

in other words , The focus of this kind of testing is “ fine-tuning ”, By adjusting the hardware and software , Find out how they are at their best , Bring the system to the strongest state .

 

Reliability test

In the case of loading certain business pressure on the system , Run the system for a period of time , To check whether the system is stable .

characteristic ：

1、 The main purpose of this performance testing method is to verify whether it supports long-term stable operation .
2、 This kind of performance test method needs to run under pressure for a period of time .（2~3 God ）
3、 In the process of testing, we need to pay attention to the operation of the system .

in other words , The focus of this kind of testing is “ Stable ”, There's no need to put too much pressure on the system , As long as the system can be in a stable state for a long time .
