JMeter cross thread parameter association requires no script

Jmeter Cross thread parameter correlation requires no script

In multithreaded operation , We may need to find the required content in the response data , Extract this content and use it as the data rented by the next thread , To this end, I bring you a simple method ！

One 、 The demo website is public 、 We use utf-8 The encoding format of , At the same time, we set up Chinese

Get into jmeter Of bin Under the table of contents , find jmeter.porperties file , Open in Notepad

newly added / Modify the configuration file , Maintain the good usage habits of the Chinese people 、 And the character encoding set I can understand

Change to Chinese , Tools can be used clearly

Code set in line with national conditions , This size is not out of order

Two 、 start-up jmter、 Demo start

Add thread group 、 Header correlator 、 Fruit trees —— Put on the shelf first

Pictured —— Just in case we check in the test plan ：

Run each thread group independently

  Add http request , Let's distinguish thread groups , Add a unique identifier to each thread group

Let's fill in everything that should be filled in , Here's the point

stay http Add on request xpath Extractor

xpath The extractor is http The subordinate of the request , Do not add the wrong location

Check use tidy—— Don't ask why , You have to tick

Customize a variable val（ It can be anything you want , Of course, don't write in Chinese ）

Xpath query expression ： This is the content of the response data that we need to extract

Match the Numbers ： Default -1 Represents the return of all elements , We changed it 1 Just one , It can also be 0 Any one

The default value ： You can leave it blank

In thread group A Next, add a sampler , First choice Beanshell Sampler

Open the function assistant to find setProperty, Attribute name customize a variable ,value of porperty Add to what we just defined xpath The variable of , Generate directly after completion

It can be copied directly to us Beanshell In the sampler

Although I wrote the script , We didn't write any code

Thread group A And the setting is completed , Now start setting the thread group B

  Or function assistant 、porperty, The attribute name has just been set out

  We directly generate , Can see the referenced variables ${val}, It was before xpath Variable

  Finally, add our function —— Be accomplished

  The verification results , Run

Extracted //title

At a glance
