I need to check if "Random Variable" generated by jmeter exist on a site in its html code. I assume i need to check it using Response Assertion, however i dont know how to reference Random Variable inside Response Assertion.
If your variable is called in Random Variable:
myVar
Then add a Response Assertion and in Patterns to check, add:
${myVar}
Which would end up like:

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"
I want to determine if a specific string exists in a HTTP response. If it does, I want to set a user defined variable to TRUE, and if it does not, I want to set it to FALSE. I do not want to pass/fail the test based on this. I just want to know if the response has the string or not. Then, once I have that answer stored in my user defined variable, I will use that variable in the jmeter IF controller to perform other actions based on the answer.
I have tried using the beanshell assertion with the following code, but my pre-defined user variable, called stringExists, is not getting updated to correctly reflect if the response has the string or not:
vars.get("stringExists");
if (new String(ResponseData).contains("this is the string I expect")) {
vars.put("stringExists","TRUE");
}
else {
vars.put("stringExists","FALSE");
}
What am I doing wrong?
There is nothing wrong with your code, you can use Debug Sampler in order to "see" the generated variable:
Also be informed that starting with JMeter 3.1 you're supposed to be using JSR223 Test Elements and Groovy language for scripting so you should consider switching to the JSR223 Assertion. As there is no ResponseData shorthand there you will need to amend a code a little bit:
if (prev.getResponseDataAsString().contains("this is the string I expect")) {
vars.put("stringExists","TRUE");
}
else {
vars.put("stringExists","FALSE");
}
I'm trying to get a variable's value from liquid in Elsa workflow but it's not working,
it just shows the variable's name in c# code.
The value you are showing in your screenshot is correct: the Body property provides you with the unparsed contents.
To get the parsed content, use the expressionEvaluator service you have there in your OnExecuteAsync method. Which you already do: just make sure to inspect (and use) the body variable.
I have an http request that uses an extractor to set a JMeter variable (lets call it test) from the body. When I look at the debug controller I can see this works fine. Next I want to append something to the beginning of the variable so I add a user defined variable node and add a variable with the name new and I set the value to ${test}. However when I look in the debug response I see ${test} instead of the value.
I tried the same thing setting the value manually in 2 different UDV nodes and it works fine, so how do I append to a JMeter variable declared in an extractor?
As per JMeter Documentation:
The User Defined Variables element lets you define an initial set of variables, just as in the Test Plan.
Note that all the UDV elements in a test plan - no matter where they are - are processed at the start.
So the User Defined Variables element will be read only once and only when the Test Plan is started.
If you need to overwrite the current variable with a new value you can go for i.e. __groovy() function, the relevant syntax would be something like:
${__groovy(vars.put('foo'\, 'some_prefix_' + vars.get('foo')),)}
Demo:
vars is a shorthand for JMeterVariables class instance, it provides read-write access to all JMeter Variables in the current thread scope. Check out The Groovy Templates Cheat Sheet for JMeter to learn what else you can do with Groovy scripting in JMeter tests
UDVs can't be used in dynamic way because they are process once at the start of the test.
Don't use UDV, use JSR223 Sampler (or PostProcessor) with vars;
vars.put("new", "prefix"+ vars.get("test"))
Another option is to use Set Variables Action plugin
I have this issue that I want to solve.
I want to create a new http request using field from previous response
I send a request
I used Json extractor to move the response string to a variable (let call this string nurl)
I used Regular expression and move the field that I want to "Reference Name"
(meanning from nurl I just want tt_cid)
Now I want to make a new call, and use that field tt_cid in my new call
How I shall call tt_cid? since it is not passed as User Defined Variables,
when I use tt_cid, I do not think J meter know it, since it is not written there, I just pulled it from the response.
Provided a Pic of what I have done
Regards to you all
Short answer call it ${tt_cid}.
since it is not passed as User Defined Variables, when I use tt_cid,
I do not think J meter know it,
For your understanding add Debug Sampler after Regular expression,
You will see all your JMeter variables, including tt_cid, which can be called as other variables ${tt_cid} inside other Samplers.
It's called Reference Name and not Variable Name because it's more complicated, You should read JMeter's Regular Expression to understand how it works internally, But basically it saves more than just 1 Variable.
