18. Jmete Java Engineering Test

1. Create a new project in eclipse

2. Introduction of two Files "Apachejmeter_core.jar" and "Apachejmeter_java.jar" to Java Engineering from JMeter's installation directory Lib/ext


Import Rack Package

Add a rack package to add

Because JMeter has its own compiled methods and classes, if not imported, compile time will be error


3. Writing JMeter Auxiliary functions


The order of execution is:
Getdefaultparameters ()-----> Setup Test (javasamplercontext context)----->runtest (Javasamplercontext context) ----->teardowntest (Javasamplercontext)
Give parameters-----> Initialize-----> Run-----> End

Instance code:
Package com.jmeter_test;
Import org.apache.jmeter.config.Arguments;
Import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
Import Org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
Import Org.apache.jmeter.samplers.SampleResult;

Common methods:
1) addargument (*name*,*value*) Defining parameters
2) Samplestart () defines the beginning of the thing, similar to the LR start transaction of LR, and the same thing as LR do not put irrelevant code between things
3) Sampleend () defines the end of the thing, similar to the lr_end_transation of LR
4) setsuccessful (true,false) Set the result or failure of the operation results, jmeter statistical results fail, in the aggregation report can reflect

4. Export the project to a jar, placed under the $jmeter installation directory $/lib/ext/, other dependent jars placed under the installation directory/lib/

Select the project you want to export--->file--->export---->java---->java file--->next----> in the path to the Java file, select Place in $jmeter installation directory $/lib/ext/, the Java file is called Strtrest.java-----> tick the items that need to be exported------>finish


5. Run the script
1) Select "Test Plan" on the left side of the main interface, right-click menu-Add--->threads (Users)---> Thread Group
2) then select the new thread group, right-click menu-Add---Sampler---java request
3) Select the new Java request, right-click menu---Add---monitor---aggregation report
4) In the Java Requests tab, you can select the class name you want to test, and in the thread group option, you can enter the number of times you want to loop and the number of concurrent
