Tool composition in JMeter

Jmeter Tool components
1） Resource producer ： Used to generate the server during the test 、 The resource code of the load machine
2） User runner ： It's usually a script run engine , Simulate the specified user behavior according to the script requirements
3） Report Builder ： Generate reports according to the real-time data in the test , Provide visual data display mode
4） Load generator ： Used to generate loads , It usually simulates user behavior in the form of multi thread or multi process

5）TestPlan ： Used to describe a performance test , Including all relevant functions of this performance test

6）Thread (users) Thread group
–setup Thread group ： A special type of ThreadGroup, Can be used to perform pre test operations
–teardown Thread Group ： Can be used to perform post test actions
–Thread Group（ Thread group ）： Normal thread group , It can also be seen as a virtual user group

1） The configuration element （config element）： Used to provide support for static data configuration .eg：CSV Data Set config Betty data files can be formed into data pools （Data Pool）
2） Timer （Timer）： It is used to set the waiting time between operations. The waiting time is commonly used in performance testing QPS The means of .
3） Preprocessor （Per Processors）： Special handling of incoming requests before the actual request is issued
4） Post Processors （Post processors）： Yes Sampler After sending the request, the server response is processed
5） Assertion （Assertions）： The corresponding data obtained in the test is consistent with the expectation , Generally used to set checkpoints
, It is used to ensure whether the data interaction during the test is consistent with the expectation
6） Monitor （Listener）： A series of components used to process and visualize test result data .eg： Graphic results 、 Look at the fruit tree 、 Aggregate reports, etc .
7） Sampler （sample）： Send a request to the server in the performance test 、 Record response information , The smallest unit that records the response time
8） Logic controller ： There are two types of components , One is for controlling test plan in sampler The logical sequence controller that the node sends the request , The other is used to organize controllable sampler Node ,eg： Transaction controller 、 Throughput controller
