5.4 Add timers

5.6 Add monitor ：Transactions per Second

5.7 Add monitor ：Transaction Throughtput vs Threads

5.5 Add aggregation report

5.8 Other extensions ： Preprocessor

5.9 Other extensions ： Assertion

6. The test execution

7. remarks

1 Purpose of the document ：

This document is mainly about Jmeter An application practice in the process of practicing the test project , Make a brief description , For by Dubbo Interface , After the processing of the message center and MQ Distribution of , as well as MySQL Put in storage \ The test methods involved in the whole process of sending to the gateway , Make some brief explanations .

2 Scope of application ：

This document is mainly applicable to testing , Yes JMeter Unknown testers , Familiar with or already proficient in JMeter People can ignore .

3 reference ：

Jmeter API：

http://jmeter.apache.org/api/

4 Dubbo Interface test code writing

4.1 Create a project , And import dependent packages

Dependency package , It has two parts ： One part is pressure measuring tools Jmeter Required dependency package , See the screenshot below

Jmeter Examples of application practice in performance testing _java

Another part , It is a business-related dependency package :jmeter-haotest-server.jar;

Will be related to lib bag jmeter The catalog of ${Jmeter_home}\apache-jmeter-2.13\lib\ext below , And then jar Package imported into the eclipse in .

The configuration file ：

4.2 Jmeter Medium case structure （JavaSamplerClient）

We jmeter One of the complete case To inherit JavaSamplerClient This class , After inheriting this class , stay eclipse Methods that need to be rewritten will be automatically generated in , These methods are the main part of our document .

The following code example ：

The description of these methods is added to the example , Next, I will introduce how each method completes code development .

TestInit.java： Initialize the base class

Jmeter Examples of application practice in performance testing _ automated testing _08

4.3 Generate class Executable file

After the code is adjusted , Need to re clean, and run Generate the compiled executable ;

Then connect bin Catalog together copy To Jmeter In machine , Standard machine is ${jmeter_workspace_home};

5 Jmeter Test execution in

After the relevant script debugging passes , You can use pressure measuring tools Jmeter In the implementation of ：

start-up D:\apache-jmeter-2.13\bin\jmeter.bat

open ${jmeter_workspace_home}\scenarios\JMeterTestSendTemplateMsgByWeChat.jmx

function , And monitor the input of the process .

Jmeter Examples of application practice in performance testing _ Performance testing _09

The previous process is described in detail below ：

5.1 New test plan

adopt “ file ”-->“ newly build ”, Add a test plan ;

5.2 Configure thread groups

Jmeter Examples of application practice in performance testing _spring_10

As shown in the figure above , In the test plan , Add thread group ;

5.3 add to java request

Jmeter Examples of application practice in performance testing _spring_11

Add... Under thread group Java request , As shown in the figure above . Add the results as follows ：

Jmeter Examples of application practice in performance testing _jmeter_12

In the main window after adding , Select the class to be measured , And add corresponding parameters .

Include the name of the parameter 、 value ;

After adding , Preservation .

5.4 Add timers

Jmeter Examples of application practice in performance testing _java_13

According to need , Some pressure tests need to add timers , In the thread group , add to --> Timer --> Fixed timer ;

give the result as follows ：

Jmeter Examples of application practice in performance testing _ Performance testing _14

According to need , And configure the thread delay of the fixed timer ;

Add results ：

Jmeter Examples of application practice in performance testing _spring_15

5.6 Add monitor ：Transactions per Second

Jmeter Examples of application practice in performance testing _spring_16

During the test , We need to monitor relevant tps, And the thread of transaction processing ;

Then you can add corresponding items in the monitor , It is used to get relevant data after subsequent test execution ;

Jmeter Examples of application practice in performance testing _ Performance testing _17

As shown in the figure above , After adding , During test execution , In real time tps situation , It can be shown in the above table ;

5.7 Add monitor ：Transaction Throughtput vs Threads

Jmeter Examples of application practice in performance testing _spring_18

Transaction throughtput vs threads Method and tps identical ;

The monitoring results are the same , It will be displayed in real time during the implementation ;

An example is shown below ：

Jmeter Examples of application practice in performance testing _ automated testing _19

*********

5.8 Add aggregation report

Jmeter Examples of application practice in performance testing _java_20

By choice Thread group --> Monitor --> Aggregation report , After adding the aggregation report , You can see the overall results in the aggregation report ;

An example of an aggregation report is as follows ：

Label	# Samples	Average	Median	90% Line	95% Line	99% Line	Min	Max	Error %	Throughput	KB/sec
TestSendTemplateMsgByWeChat	9531	40	22	96	124	188	2	630	0.00%	55.7	0
The overall	9531	40	22	96	124	188	2	630	0.00%	55.7	0

********

5.9 Other extensions ： Preprocessor

Jmeter Examples of application practice in performance testing _ automated testing _21

For the testing of some scenarios , It may be necessary to prepare embedded data ;

Adding a preprocessor can help solve these problems ;

5.10 Other extensions ： Assertion

Jmeter Examples of application practice in performance testing _ Performance testing _22

Assertion , seeing the name of a thing one thinks of its function , Add assertions , After the test , By assertion , Direct verification and marking case Whether to pass ;

6. The test execution

Monitor relevant data during execution , And get relevant reports .

Here are some examples of test execution results ;

Jmeter Examples of application practice in performance testing _spring_23

The figure above is an interface test TPS Result pictures ;

Jmeter Examples of application practice in performance testing _jmeter_24

The figure above is an interface test thread Picture of situation results ;

7. remarks

JMeter There are more scenarios for the use of ;

This article is only a basic use example , Want to know more about , Then gradually add ;

A supplementary service started shell

A gift of rose
Fragrance in hand

We were so eager for the waves of fate , Until the end ： The most graceful scenery of life , Is the heart of calm and calm …… We used to look forward to recognition , Not until the end ： The world is its own , Have nothing to do with others ！- Mr. Yang Jiang
