JMeter First Experience/java Network request script add

Jmeter Easy to use (there are many pictures on the web, tutorials, here is just a brief description):

Jmeter software use, first create a test plan, on the test plan right-click Add ---threads< c19> (Users)-- thread group

Then Right-click on the thread group-- > Add-->SamplerHttp request .

Configure the response information in the Http request , save it

Then you need to create the result Tree of the response, create step: ( Right-click on the thread group , add-on listener- View results Tree )

You can add your own listener to your needs .

Jmeter JAVA script uses :

test with a personal, custom java script .

1. First, you need to copy it in the lib/ext package of Jmeter.

Apachejmeter_core.jar

Apachejmeter_java.jar

These two packages are in a Java project.

2. Create test class entry   implements  abstractjavasamplerclient method.

2. jar other jar package references, need   these jar package store to lib some class not found
4. here is to note that if When a network request occurs, in jmeter default Lib commons-apache-httpclient 3. X version network request package, here you can consider replacing the package or   Use the package Span lang= "ZH-CN", otherwise An exception occurs when requesting the network.
6. export jar after package, you can   jar package placed to   lib/ext  package.
8. after You create a thread group in Jmeter, create a Java request, and if the path is placed correctly, the The test class. Once you have created a listener such as the corresponding result view tree , you are ready to listen.

The Java request class is posted here for reference:

The Sampleresult can be used to print display information: for example:

Therefore, the information in the Sampleresult needs to be set.
