How do I pass data from one thread group to another in JMeter?

How do I pass data from one thread group to another in JMeter?

Step to implement the logic for passing the variable value to another Thread Group:

1. Add a ‘Regular Expression Extractor’ post-processor as a child element of 1.1 HTTP Request (Fetcher) and fetch the value in a variable (say employeeID)
2. Add a ‘BeanShell Assertion’ and write ${__setProperty(valueToPass,${employeeID})}

How pass data from one API to another in JMeter?

Testing Webservice with JMeter: Passing data from one response to another request

1. Create a web service (WS) test plan, as described in the tutorial (in my case it contains two WS calls)
2. Add the User Defined Variables config element to the test plan and define there a variable for transferring the response data.

How do I run two thread groups in JMeter?

Resolution

1. Combine the thread groups in a single JMX. All thread groups run concurrently unless specified differently in the test plan.
2. Store the samplers of each JMX in one thread group in a single JMX under a Parallel Controller .
3. Create a test for each JMX and combine them in a Blazemeter multi test.

How do I make a variable global in JMeter?

First we create a setup thread group and under that user defined variables. We then define the specific environment variables to use across the test plan. preprod. With the user defined variables set we then need to write them to global variables (properties).

How does JMeter calculate thread count?

To get the number of the current thread (out of 5 in your case) use ctx. getThreadNum() which will get the number of the thread. To get the total number of threads being used by jMeter you can use ctx. getThreadGroup().

What is JMeter thread group?

3.1 Thread Group As the name implies, the thread group element controls the number of threads JMeter will use to execute your test. The controls for a thread group allow you to: Set the number of threads. Set the ramp-up period. Set the number of times to execute the test.

How to pass a variable from one thread group to another in JMeter?

I have a JMeter test with 2 Thread Groups – the first is a single thread (which creates some inventory) and the second has multiple threads (which purchase all the inventory). I use BeanShell Assertions and XPath Extractors to parse the returned value (which is XML) and store variables (such as the ids of the items to be purchased).

Where does the value come from in JMeter?

The value comes in the response of the request of the First Thread Group needs to be passed in the Second Thread Group. Each Thread Group has 1 request. To make them more understandable, let’s call them fetcher and consumer.

How to pass a value between thread groups?

Parameterize the value using JSON extractor (use the relevant post-processor according to your scenario ) Right Click > Add > Post Processors > BeanShell PostProcessor In the BeanShell PostProcessor, you can create a property by using parameter which creates in the first step You can use the created property in any Thread Group.

How to pass a variable from one thread to another?

Or, we can use a BeanShell PreProcessor to manipulate the variable: In the BeanShell PreProcessor, we can access the variable passed in from another Thread group, by using props.get (“name_of_variable”). We can then perform some String manipulation and save the result as a new variable.
