Am new to JMeter. I have extracted my required values from response data using regular expression extractor. Now I need to use these etracted values to select a particular data from the list.
I have few data listed. In these data, few have edit enabled and few data's edit are disabled. I have to instruct JMeter to select data that have edit enabled. there are 3 conditions to have edit enabled which is:
is_final = 1
is_locked = 0
status_id = 1
I have extracted these values from response data. But I donot know how to use BeanShell to instruct JMeter to select data that have edit enabled. Please help me on this.
the syntax of the Beanshell script is quite similar to Java. Say, you have a list of elements: ArrayList<element> list and each element has fields:is_final,is_locked,status_id, so you can write a loop to go through all the elemnts in the list like
for(int i = 0; i < list.size(); i++){
if(list.get(i).is_final == 1 && list.get(i).is_locked == 0 && list.get(i).status_id == 1){
return list.get(i);
}
hope this is helpful to you!
about jmeter's introduction on beanshell and beanshell's offifical wiki
If you want to use the single values out of Extracted array. First you need to understand these variables are stored as for eg:MYREF_g0,MYREF_g1,MYREF_g2
So if you wanted to extract say status_id in your case which is stored at 3rd array position in ReferenceName say Abc. then refrence variable name should be${Abc_g2}.
Same applies for other values like ${Abc_g0},${Abc_g1}.
Hope this helps.!

Below is the code which i have been trying to address the below UseCase in JMETER.Quick help is appreciated.
Usecase:
A particular text like "History" in a page response needs to be validated and the if the text counts is more than 50 a random selection of the options within the page needs to be made.And if the text counts is less than 50 1st option needs to be selected.
I am new to Jmeter and trying to solve this usingJSR223 POST processor but somehow stuck at vars.put function where i am unable to see the desired number being populated within the V paramter.
Using a boundary extractor where match no 1 should suffice the 1st selection and 0 should suffice the random selection.
def TotalInstanceAvailable = vars.get("sCount_matchNr").toInteger()
log.info("Total Instance Available = ${TotalInstanceAvailable}");
def boundary_analyzer =50;
def DesiredNumber,V
if (TotalInstanceAvailable < boundary_analyzer)
{
log.info("I am inside the loop")
DesiredNumber = 0;
log.info("DesiredNumber= ${DesiredNumber}");
vars.put("V", DesiredNumber)
log.info("v= ${V}");
}
else{
DesiredNumber=1;
log.info("DesiredNumber=${DesiredNumber}");
vars.put("V", "DesiredNumber")
log.info("v= ${V}");
}
def sCount = vars.get("sCount")
log.info("Text matching number is ${sCount_matchNr}")
You cannot store an integer in JMeter Variables using vars.put() function, you either need to cast it to String first, to wit change this line:
vars.put("V", DesiredNumber)
to this one
vars.put("V", DesiredNumber as String)
alternatively you can use vars.putObject() function which can store literally everything however you will be able to use the value only in JSR223 Elements by calling vars.getObject()
Whenever you face a problem with your JMeter script get used to look at jmeter.log file or toggle Log Viewer window - in absolute majority of cases you will find the root cause of your problem in the log file:
How to ensure/handle duplicate values are not getting captured while using regular expression?
In my scenario i need to capture multiple offers from my response. But cant use the same offers again and again within the transaction
There are multiple ways to do this. If you are using the default Regular Expression Extractor, the problem is it creates the variables (eg: offer_1, offer_2 etc), ready to go with the execution. It would've been easier if it returned a ArrayList of some sort where we can remove the duplicates. What I am about to suggest is to add those variables to a list in a JSR223(groovy) sampler/post processor then convert them back to usual jmeter variables to use in the usual jmeter script flow.
Snippet:
I created a sample script as per your description which would return multiple offers with some duplicates. Following is the state of jmeter variables before post processing.
offer_1=RUSSIA
offer_1_g=1
offer_1_g0=offer="RUSSIA"
offer_1_g1=RUSSIA
offer_2=UK
offer_2_g=1
offer_2_g0=offer="UK"
offer_2_g1=UK
offer_3=ICELAND
offer_3_g=1
offer_3_g0=offer="ICELAND"
offer_3_g1=ICELAND
offer_4=USA
offer_4_g=1
offer_4_g0=offer="USA"
offer_4_g1=USA
offer_5=UK
offer_5_g=1
offer_5_g0=offer="UK"
offer_5_g1=UK
offer_6=USA
offer_6_g=1
offer_6_g0=offer="USA"
offer_6_g1=USA
offer_7=USA
offer_7_g=1
offer_7_g0=offer="USA"
offer_7_g1=USA
offer_matchNr=7
As you can see above there are duplicates in the variables. Put the following Groovy code in a JSR223 post processor with groovy as language selected.
// Count of offers extracted by Regular Expression Extractor
def count = Integer.parseInt(vars.get("offer_matchNr"))
// An empty list which will store the offers
def offer_list = []
for (int i = 1; i <= count; i++){
def offer = vars.get("offer_" + i)
offer_list.add(offer)
}
// Removes the duplicates in the list
offer_list.unique()
// Following one liner adds new variables but with only unique offers in similar format as jmeter variable.
offer_list.eachWithIndex{ it, index -> vars.put("unique_offer_${index+1}", "${it}")}
After post processing:
unique_offer_1=RUSSIA
unique_offer_2=UK
unique_offer_3=ICELAND
unique_offer_4=USA
I have scenario where I need to capture dynamic Order-value IDs from response and among those values, I need to select maximum value and pass it to the next request.
How can we achieve this with the help of Jmeter tool?
Assuming you have the following JMeter Variables from the PostProcessor:
foo_1=1
foo_2=5
foo_3=10
foo_matchNr=3
You can get the maximum value as follows:
Add JSR223 PostProcessor as a child of the request, make sure it goes after the PostProcessor which returns your Order-ID values
Put the following code into "Script" area:
List values = new ArrayList()
for (int i=1; i <= (vars.get('foo_matchNr') as int); i++) {
values.add((vars.get('foo_' + i) as int))
}
vars.put('foo_max', Collections.max(values) as String)
Assuming everything goes well you should be able to access the maximum value as ${foo_max} where required.

In j meter: In a bean-shell assertion or any other I want to match the content of response which I have fetched using Jason extractor suppose:
Result[1]=A, Result[2]=b, Result[3]=c
and so on Versus variables I have fetched using JDBC pre-processor which has saved as:
Result_1=, Result_2=B, Result_3=c.
I am able to match 1 variable at a time but not all at one time. so need help with bean-shell code to compare all result at once.
Add JSR223 Assertion somewhere to your test plan (normally as a child of a Sampler you would like to fail)
Put the following code into "Script" area
for (int i = 1; i <= Integer.parseInt(vars.get('ResultFromJSON_matchNr')); i++) {
if (!vars.get('ResultFromJSON' + i).equals(vars.get('ResultFromJDBC_' + i))) {
AssertionResult.setFailure(true)
AssertionResult.setFailureMessage('Variables mismatch')
}
}
Make sure you have groovy selected as the "Language" and have Cache compiled script if available box ticked
The above script assumes ResultFromJSON and ResultFromJDBC JMeter Variables reference names, amend them according to your real definitions.

I'm landing into a page where some Customers listed out. I'm retriving all the Customer Ids by Regular Expression Extractor Post-Processor.
Now, in a subsequent request I need to pass those Ids. It's being passed as a 'Body Data' by the following format:
[19327,15947,14421,18813,20942]
Let say, there are 5 Customer Ids retrived, then I can use the variables for each record as follows:
Passing Variables: [${CustomerId_1},${CustomerId_2},${CustomerId_3},${CustomerId_5}]
Posting Variable Values: [19327,15947,14421,18813,20942]
But let say, there are only 3 Customer Ids retrived, and if I pass the variables as above then the sampler will fail because currently it just retrived 3 Customer Id records.
Passing Variables: [${CustomerId_1},${CustomerId_2},${CustomerId_3},${CustomerId_5}]
Posting Variable Values: [19327,15947,14421,${CustomerId_4},${CustomerId_5}]
How to deal with this issue, plz. do help.
Thanks in advance
Add Beanshell PreProcessor as a child of your 2nd request
Put the following code into the Pre-Processor's "Script" area
int customers = Integer.parseInt(vars.get("CustomerId_matchNr"));
StringBuilder requestBuilder = new StringBuilder();
requestBuilder.append("[");
for (int i = 1; i <= customers; i++) {
requestBuilder.append(vars.get("CustomerId_" + i));
if (i != customers) {
requestBuilder.append(",");
}
}
requestBuilder.append("]");
sampler.getArguments().getArgument(0).setValue(requestBuilder.toString());
The above code will build required request line depending on number of matches and automatically set request body.
Referenced classes:
vars - shorthand to JMeterVariables
sampler - provides access to the parent sampler, in case of HTTP Request it will be HTTPSamplerProxy
StringBuilder - comes with Java SDK
See How to Use BeanShell: JMeter's Favorite Built-in Component guide for more information on Beanshell scripting, explanation of pre-defined variables and some useful examples.
refName_matchNr will return the number of matches. So in your case CustomerId_matchNr will give you number of customerIDs.
Use a beanshell pre-processor to run a loop and construct the BodyData string and save it to a new variable, use that variable in your subsequent sampler.
