How to use logn function in Jmeter? Is it any addition addon required to use it? Is there any other option available in Jmeter to do the same operation?
I am trying to extract the Output from the response and assigning it to a variable,
Please any one help me..
The easiest way to extract the Output from the output from the response and assign to a variable, you want to use Regular Expression Extractor:

logn - is this what you're looking for ? The input needs to be a string for logn ?

I ran into a problem in JMeter.
I have URL and into body there is GET http://test.com/registration?test={value} and I need to extract value of test parameter and put this value to the next url to another parameter.
I used Regular Expression Extractor but all I can do is pull out the whole URL but not specific value from the URL.
By way of example:
http://test.com/browse where we have code 303 and in the body
See Other.
I need to extract value from http://test.com/registration?test={value} and put this value to the another URL
If you have any thoughts on this please help. Thanks in advance!

Probably there are any other ways to solve it.
Try with this regular expression:
test=(.+?)"
Full configuration just in case:
You will be able to refer extracted value as ${value} where required.
You might find Boundary Extractor easier to use, in this case you just need to provide "left" and "right" boundaries and it will extract everything in-between:

I'm capturing multiple values with a regular expression, and that expression returns 20 matches as shown in image RegExMatches,
My regular expression is something like this RegEx.
How do I use multiple values in post data of my HTTP request which is something like PostData
I tried with MatchNR and -1 and call with ${candidateGUID_gN} N being the match number but this didn't workout.
How do I use the Extracted values in Post data ? or will I have to make different Regular Expressions for each value ?
I think the only way of achieving this is building your request using JSR223 PreProcessor and Groovy language, take a look at the following JMeter API shorthands:
Arguments
vars aka JMeterVariables
sampler aka HTTPSamplerBase

This is how my HTML value looks like. Please note, there is a carriage return and space after q1. I only want to extract the number next to q as here it is 1.
<span id="sqa">q1
?</span>
I am using Xpath extractor, and it gives me complete value as can be seen via debug sample. The name of my variable is answer_value. I only wanted 1 which is a dynamic number here, not q. As only this number is used in the subsequent request.
Xpath query I am using is //span[#id="sqa"] and it gives me below value. I am not sure how I can split this value in Xpath or need to use a split function of JMeter to do that?
answer_value=q1 ?
Just add a Regular Expression Extractor and configure it to extract a number from the answer_value JMeter Variable.
Place it below the XPath Extractor and configure like this:
You might also want to apply XPath normalize-space() function to remove eventual line breaks:
normalize-space(//span[#id="sqa"]/text())

I have issue with debug sampler not showing regular expression extractor in Jmeter. Kindly refer the tree below:
Here is the information in my regular expression extractor:
There's no regular expression variables shown in debug sampler output:
Can help to see what's the real issue here? FYI I'm scripting using webtours demo website & havent parameterize username and password yet coz i want to make sure my correlation works first. Thanks.
Without seeing the response it's hard to say what is wrong, most probably your Regular Expression Extractor fails somewhere somehow, as per documentation:
Template
The template used to create a string from the matches found. This is an arbitrary string with special elements to refer to groups within the regular expression. The syntax to refer to a group is: '$1$' to refer to group 1, '$2$' to refer to group 2, etc. $0$ refers to whatever the entire expression matches.
so for sure you need to change $1 to $1$
Using regular expressions for parsing HTML is not the best idea, I would recommend consider using CSS Selector Extractor instead, the relevant configuration would be something like
I don't think your PostProcessor placement is correct, it's a Post processor so according to the JMeter test elements execution order it is executed after the sampler and you're trying to use the variable in the same request. So my expectation is that you need to move it under the "Homepage" sampler
Add HTTP Cookie Manager to your Test Plan
I need to run a loop until text in response data is Completed for a HTTP request.
My while loop is going in infinite loop. I am not sure how to fix it. Any help would be appreciated. Thanks!
Use debug sampler and ensure the value is correctly captured as ' completed '. Your regular expression seems to be wrong. It should besomething like:
Status:"(.*?)"
You can use regular expression tester in response data to validate the regular expression.
