Performance features focus & JMeter & LoadRunner advantages and disadvantages

Which test tool is better ？

Many testers , I don't know which performance testing tool is suitable ？ Which is better for you ？

Such problems can be summarized as follows , Then watch some tutorials , Understand the advantages and disadvantages , Find the right tools for yourself , Or use different tools in different scenarios

Jmeter

advantage ：

1. Free open source , Simple installation

2. Help testers easily simulate the environment where multiple users access the server at the same time

3. Wide application

4. Rich logic controller

5. Powerful monitoring components

Inferiority ：

1. Unable to judge the test 【 correctness 】.Jmeter Although there is an assertion mechanism , However, when simulating multi-user operation, the response after making a request is unpredictable

2. Not very good BeanShell Test mechanism

LoadRunner

loadRunner It is a commercial performance testing tool , It can be used to predict system behavior and performance load testing

It identifies and finds problems by simulating the implementation of concurrent responsibility and real-time performance monitoring by tens of millions of users ,LoadRunner Be able to test the entire enterprise architecture . By using LoadRunner, Enterprises can minimize testing time, optimize performance and accelerate the release of application systems

This software needs to be paid , Therefore, the software is generally purchased in the form of a company or pirated

advantage ：

LoadRunner The emphasis is on the whole enterprise system , It simulates the operation behavior of actual users and implements real-time performance monitoring , To help identify and find the problem faster . Use LoadRunner Of VirtualUser Gennerator engine , It can easily simulate the load of the application system . The engine can generate agents and virtual users to simulate business processes and the operation behavior of real users

1. Stable operation

2. Monitoring indicators are complete

3. The performance test results are detailed

4. Simulate tens of millions of users to implement concurrent load and real-time performance monitoring to confirm and find problems

Inferiority ：

1. charge , And it's expensive

2. The installer is complicated , Difficult operation

Locust

Officially describe it “an open source load testing tool”. But the other two tools are quite different from the previous two , Compared with the previous two tools , The function is much worse , But it's not without advantages

1.Locust Based solely on python programing language , use Pure Python Describe the test script , also HTTP The request is entirely based on Requests library . except HTTP/HTTPS agreement ,Locust You can also test other protocol systems , Just use python Call the corresponding library to describe the request

2.LoadRunner and Jmeter Adopt the test function of process and thread , It is difficult to simulate high concurrent pressure on a single machine .Locust The concurrency mechanism of the system discards processes and threads , Adopt the cooperation process （gevent） The mechanism of . Coprocessing avoids system level resource scheduling , This can greatly improve the concurrency of a single machine
