I want to get the max number of loops in the test group. But how?
I do not see anything to do with loops here
JMeterContextService.getContext().getThreadGroup()
Number of loops is not about the Thread Group, it is property of the underlying Loop Controller so you need to amend your code like:
ctx.getThreadGroup().getSamplerController().getProperty('LoopController.loops')
Demo (assumes using __groovy() function):

You can follow the convention of setting loop count as a property for example using ${__P(loopCount)}. Then get the property number with default in groovy:
props.get("loopCount", "1") as Integer
This is assuming you call JMeter with overriding property, for example:
jmeter -n -t -JloopCount=6 my.jmx

I am using JMeter's Function Helper Dialogue and i found below syntax -
Syntax - ${__Random(12,99,customer-id)}
Result - random values b/w 12 to 99 getting generated, which will get stored in variable "customer-id"
Now Problem is I have to generate value with prefix 'test' (say-test12) and store it in variable 'customer-id'
How to do that ?
I don't see why would you need this because JMeter Variables can be normally concatenated with plain text so if you need test12 just use test${customer-id} statement where required.
However if you really need to generate some static text followed by a random number you could go for __groovy() function configured like:
${__groovy('test' + org.apache.commons.lang3.RandomUtils.nextInt(12\,99),customer-id)}
Demo:

Apache Groovy - Why and How You Should Use It
I have two variables (create_date) took from SQL queries, and I want to validate the results.
Using Regular Expression I fetch both created date and I want to make sure that the dates is not equal.
I have created the following BeanShell assersion to compare both variables:
enter image description here
however, I'm getting the following error:
enter image description here
You're mixing 2 approaches:
Referencing variables like ${CreateDateBefore} in scripts (which you should not be using at all)
And using vars shorthand for JMeterVariables class instance
Apart from this you're using double to store some form of a timestamp
So you need to update your code like:
String var1 = vars.get("CreateDateBefore");
String var2 = vars.get("CreateDateAfter");
Also be aware that since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for scripting so consider migrating to JSR223 Assertion
And last but not the least, you can compare 2 JMeter Variables using "normal" Response Assertion configured like:
I'm using jmeter and I would like to automate below scenario :
(In general I would like to increase value, I already know how to extract value from previous request)
Execute request_1
Extract value1 from request_1 using Regular expression extractor
Increment value1.
Put new value (increased) to the request_2
Any idea how can I achieve it ?
Check out __intSum() function, you can sum an arbitrary number of arbitrary integers via it.
Given you have a JMeter Variable called yourVar where the extracted value lives, the relevant __intSum() function configuration to increment ${yourVar} value by 1 will be something like:
${__intSum(${yourVar},1,yourVar)}
Demo:
If the value you're getting from the Regular Expression Extractor is more than 2 147 483 647 you will need to use __longSum() function instead.
See Apache JMeter Functions - An Introduction guide for more information on JMeter functions concept.
I have assigned a variable ${WH} to 22 and now want to assign ${WH} to another variable called ${W_ID}. I have tried a couple of things, but none of them seem to be working.
None of below working (used in User Defined variable page):
W_ID=${__eval(${WH})}
W_ID=${__evalVar(WH)}
W_ID=${__V(${WH})}
I can't figure out why the value doesn't get stored in W_ID. How can this be done?
You can add JSR223 Sampler language can be Javascript and write:
vars.put("WS_ID", vars.get("WH"))
This will move WH value to WS_ID variable.
There's an issue if you are using multiple User Defined Variables, later assignment can override previous assignment, try to avoid it. The reason can be found in manual:
Note that all the UDV elements in a test plan - no matter where they
are - are processed at the start.
You can use the __groovy() function available since JMeter 3.1.
The relevant Groovy expression which will read ${WH} variable value and save the result into ${W_ID} variable will look something like:
${__groovy(vars.get('WH'),W_ID)}
Demo:
You can put the function anywhere in your script. See Functions and Variables JMeter User Manual chapter for more information.
I want to add 2 kind of parameters to a post request.
From an http request I extract 2 list of variables:
Order_id = input type="hidden" name="(drag.+?)" value="(\d+?)"
Weight_id = class="draggableviews-weight form-select" id=".+?" name="(drag.+?)"
In the Post Request that follows, I need to repost all this variables. I use a BeanShell PreProcessor for this. The first list is no problem, since this get the same value. The second list should get a new random value between -50 and 50. I also want a different random value for each iteration.
How should I do this ?
If I use Random Variabele Config Element I get the same random int for each variabele. I want a different one for each iteration.
enter image description here
I would recommend using ThreadLocalRandom.nextInt() method like
sampler.addArgument(name2, String.valueOf(java.util.concurrent.ThreadLocalRandom.current().nextInt(-50, 51)));
Don't inline JMeter Functions into Beanshell scripts, either pass them via "Parameters" section and refer via Parameters or args shorthands or use appropriate code-based substitutions.
See How to Use BeanShell: JMeter's Favorite Built-in Component guide for more information on Beanshell scripting in JMeter tests.
To retrieve multiple values from single Regular Expression Extractor, we use Templates as follows:
then refer groups as follows:
In the image, you can see that link is Reference Name and there is only match found with the regular expression.
number of matches is : link_matchNr
first group value : link_1_g1
second group value : link_1_g2
Note: The regular expression I tried on is google.com, you can also simulate the same as follows:
Use Random function as follows:
value2 = ${__Random(-50,50)};
log.info("valuee2 " + value2);
Use Random Variable:
then, refer Output Variable in Beanshell Preprocessor as follows:
value2 = vars.get("randomInt");
