I have a requirement to use randome url from a url list I extract from a json response.
Say I extract them in this mannser
imageUrls_1=https://blah01.com
imageUrls_2=https://blah02.com
imageUrls_3=https://blah03.com
imageUrls_4=https://blah04.com
imageURLs_matchNr=4
In a following JSSR223 sampler I was able to generate a variable called "url" with one of the url names selected randomely
("imageUrls_1","imageUrls_2",etc)
I was thinking to use them in my HTTP request to get the correcponding url as follows. ${${url}}. But soon found out its not giving me anything other than "${${url}}" :(.
JMeter Is it possible to place a varibale inside a varible name?
Basically I need to use one of the extracted urls randomely in my HTTP request.
The easiest way is going for __V() and __Random() functions combination like:
${__V(imageUrls_${__Random(1,${imageURLs_matchNr},)},)}
Demo:

Use __V function
${__V(url)}
The V (variable) function returns the result of evaluating a variable name expression.

in one of my steps in the Jmeter script, I'm using json extractor to read a value from a key(address) in the JSON response and store it in a variable called "TypeOfRequest." In the next step, I need to check if the "TypeOfRequest" value is null or not(There can be situations I don't find that key in the JSON response). Then I need to take a different route.
Snippet how I'm getting the TypeOfRequest from Json extractor $.communicationMethods[:1].hTTPS.address
So my question is, how do I check if TypeOfRequest has a value or not in the if controller?
tried using '${__javaScript(vars.get("TypeOfRequest") == null)}(ref https://www.blazemeter.com/blog/jmeter-if-controller and https://sqa.stackexchange.com/questions/32969/how-do-i-check-if-a-variable-is-null-using-a-if-controller) but unable to go through the if condition, can someone help me with this. Thanks in advance
Just use Debug Sampler to see what JMeter Variables are defined and inspect their values, my expectation is that you're "unable to go through the if condition" because your TypeOfRequest variable is not null, i.e. it's present but it's an empty string.
Also the referenced article suggests using __groovy() or __jexl3() function so I believe if you change your condition to something like:
${__groovy(org.apache.commons.lang.StringUtils.isEmpty(vars.get('TypeOfRequest')),)}
you will be able to "go through the if condition"
In the JSR Sampler I am assigning the value of a String I create i.e., SFDC_Prouct_1 in list. for e.g.,
list=SFDCProduct_5
Here SFDCProduct_5 is already a variable which has XML elements. Now I am trying to place a http request and in the payload I want to inject the value of SFDCProduct_5 . But I have to write ${list}, as list has the value of SFDCProduct_5 .
I tried ${${list}}, but thats not working.
Any ideas?
In JSR223 Sampler you can get the nested variable using vars.get
vars.get(vars.get("list"));
If I correctly understood your question you need to wrap your ${list} into __eval() function like
${__eval(${list})}
Demo:
See Here’s What to Do to Combine Multiple JMeter Variables article for more information if needed.
I am uploading a file [.xml] to be the body of the POSt HTTP request. But the file has a variable ${TEVAM} whose value is being fetched from the previous request and being assigned.
But the value is not being replaced.
What should I use here?
In order to get the nested variables resolved you need to use __eval() function as a wrapper for i.e. __FileToString() function like:
${__eval(${__FileToString(test.xml,,)})}

I am using Jmeter for my performance testing and I am stuck at the point where I need to extract the value from the URL and pass it to Jmeter.
Here is the example:
Application requires user to create an order and then submit it on the next page
I am at a point where I can create an order using Jmeter.
In order to create a script to submit an order I have copied the url from the web page as passed it as a GET method '/order/submit/23'. This '23' number changes everytime I create a new order
The issue I am having here is when I run my jmeter script it creates another order with another number which then mismatch with the '/order/submit/23' url I have passed.
Is there any way to extract this number from the HTML code and pass it to Jmeter?
I looked into the HTML code and this number is a part of URL so not sure how I can extract it. Any suggestions please
I am looking for something like /order/submit/${var}
Thanks
If I understood you correctly, you need to extract some value from response. You can do it with two samplers:
XPath Extractor
RegEx extractor
I think xpath extractor more appropriate in your case
I have a test plan in JMeter that has a Response Assertion where I'd like to use a variable that comes from a CSV Data Set Config. So my Pattern looks like:
${assert1}
Which corresponds (at least in my thoughts) to what comes from the file used in CSV Data Set Config, but it doesn't work. I have seen multiple suggestions to use a Regular Expression Extractor, but the examples I saw refer to something they're trying to capture from a page. In my case I am using an external csv file.
My question: how can I use a variable as input for a Response Assertion pattern ?
I have successfully used a CSV Data Set Config as a source of string that I use in a url parameter, and then use a Response Assertion to seek out that parameter in the response.
Variable name: P.
URL: /product/${P}.
The response assertion Parterns to Test: ${P}.
I wonder if it is not necessary to use the CSV data variable in the request in order for it to be available in the response assertion?
If my understanding is right,
here your problem:
You want to use the value from your CSV as part of URL and that too via variable.
Solution:
Configure your CSV Data Set Config like this:
Filename: url csv path
variable name : assert1
Delimiter : , (if your CSV comma separated)
leave remaining unchanged
That's it you can use the variable assert1 anywhere: ${assert1}.
