I have a JMeter script with
-Thread Group
- While Controller
-SOAP/XML-RPC Request
-Regular Expression Extractor
Extractor gets response code, While controller checks if it's = "200"
(${__javaScript("$errCode)== "500";)})
And for some reason, it doesn't loop.
But if replace SOAP request with HTTP request it's looping.
How can I loop with while SOAP request?
According to Apache's manual: "Otherwise - exit (or don't enter) the loop when the condition is equal to the string "false""
Apparently, SOAP/XML-RPC Request is failed and that's the reason why loop didn't start

I'm new using JMeter and I have this case:
Test Plan
Test Group1
Http Request 1
Json Extractor1
BeanShell Assertion1
Http Request 2
Http Request 3
And I want to use the response of HTTP req 1(extracted in JSON extractor) in both HTTP request 2 and 3. For request 2 is working fine I just use ${response} and works fine but when I try to user the same variable in request 3 is like is empty is not showing anything.
So I tried to put the BeanShell Assertion and do a var.set or even a set property, but is still not working. It is like the var or property is being set, and I can see them in HTTP req 2 but in HTTP req 3 they are empty.
Is there another way to set the variable or the response of the request 1 to be use in any other requests of the same thread?
Thanks
You need to amend your test design and make the JSON Extractor a child of the Http Request 1
Test Plan
Test Group1
HTTP Request 1
JSON Extractor
HTTP Request 2
HTTP Request 3
If you have JSON Extractor at the same level as HTTP Requests 1-3 it's being executed after every of them so it tries to extract the value from HTTP Request 2 response, doesn't find it and the variable gets empty or default value.
The same applies to the Beanshell Assertion.
More information: JMeter Scoping Rules
With regards to using Beanshell in general it's not very recommended, since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language
I have test plan with following request in sequence with 2 loops.
ApiHttp request
Mqtt request
I need to run 1st loop & verify API reaponse is true or false:
If it's true, run Mqtt request , else start the 2nd loop and same verify the API response, if it's true run Mqtt else stop.
In above scenarios, I put beanshell to read the API response:
vars.put("response", new String(data));
But don't know how to verify of its true or false & execute the Mqtt. Any help pls.
Add If Controller as the very first test element under the Thread Group and use the __groovy() function as the condition:
${__groovy(vars.getIteration() <= 2,)}
Put ApiHttp request as a child of the If Controller
Add another If Controller after the ApiHttp request and use the following __groovy() function as the condition:
${__groovy(ctx.getPreviousResult().getResponseDataAsString().contains('true'))}
Add Mqtt request as a child of the If Controller
Add Flow Control Action sampler after the Mqtt request and configure it like:
First switch from Beanshell to JSR223 Test elements and use Groovy.
Use If Controller and just put in it:
${response}
To stop the test based on iteration number, be aware that a Loop Controller exposes iteration as a variable based on name of variable, for example if your LoopController is named LC, then you can access iteration as:
vars["__jm__LC__idx"].toInteger()
And to stop a test from Groovy using JSR223 Assertion you can throw:
throw new org.apache.jorphan.util.JMeterStopTestException();
See:
https://jmeter.apache.org/api/org/apache/jorphan/util/JMeterStopTestException.html
The services I'm trying to test, will work on long pooling method.
They won't give results in first response.
When I run my API script I am not getting full response in first time.
How can I wait in this case for the remaining portion of response to be received?
I want to use values from this response into next call..
In the above screen my response should wait when complete:True
As far as I understand your requirement you need to repeat the Gethotels request until complete attribute becomes true.
In order to accomplish this:
Add a JSON Extractor as a child of the Gethotels request and set it up as follows:
Put your Gethotels request under the While Controller and use the following __jexl3() function as the condition:
${__jexl3("${complete}" != "true",)}
That's it, While Controller loop the Gethotels request until complete becomes true
In JMeter,
I have One Thread , Say T1 and it has 4 HTTP requests. Say HR1 to HR4.
I fed some data via parameterization to HR1 and I need one value from the response of HTTP request of HR1 and I need to pass it to HR2 and later HR4.
I tried Extractor's and BeanShell expression. But its not working.
I got the Answer.
I Took the "Regular Expression Extractor" from the response and put it under the first HTTP request.
In the Second HTTP request, i called the that one and it worked like Magic :)
Thanks.
I am designing a load test in JMeter.
With the current application that we have whenever a HTTP request is sent, the web server will very occasionally send back a page with a message. To get around this we just have to reload the page. This page could come up for literally any HTTP request.
Is there any way to design a test in JMeter where when a sampler fails, the sampler simply retries?
I'm not sure how I can get a Beanshell sampler to resend a HTTP request.
It is possible via additional Beanshell Assertion
You can re-run arbitrary sampler from the Beanshell Assertion as simple as
ctx.getCurrentSampler().sample(null);
Add a Beanshell Assertion after all other assertions. It matters as assertions are being executed upside-down.
Put the following code into Beanshell Assertion's "Script" area (just change "message" to what your server returns on error.
import org.apache.jmeter.samplers.SampleResult;
if (new String(ResponseData).equals("message")) {
SampleResult result = ctx.getCurrentSampler().sample(null);
if (result.getResponseDataAsString().equals("message")) {
Failure = true;
} else {
SampleResult.setSuccessful(true);
}
}
You'll have only one result recorded.
If assertion passes 1st time - it'll be successful
If assertion fails 1st time and passes 2nd time - it'll be successful
If assertion fails 2 times - it'll be recorded as failed.
For extended information on Beanshell scripting check out How to use BeanShell: JMeter's favorite built-in component guide.
Create such hierarchy:
Thread Group (1 user, 1 second ramp-up, forever)
-While Controller (empty condition = forever)
--Counter (start – 1, increment – 1, reference name – counter)
--HTTP request
---Timer (I prefer constant Timer, responseble for pause betwee retrying)
---BeanShell Post Processor
BeanShell Post Processor should contains(pseudo code):
if(Integer.parseInt(vars.get("counter")>5)
{
prev.setSuccessful(false);
prev.setStopTestNow(true);
}
if(successCondition)
{
prev.setStopTest(true);
}
There is no direct way to achieve it, but I think you can use While controller in conjuction with Regex extractor to resend the failed requests.
Logical flow could be,
1. HTTP request
2. Regex extractor post processor - check response contains failure extract value in msg variable, default is success
3. While controller - run till msg=failure, default value of msg is success

Let me know if this works.
