I have JMX structure such as,
ThreadGroup-1
Set propertyVariable-Content_0,Content_1,Content_3 etc
ThreadGroup-2
LoopController
Counter-counterNum
HTTPRequest--use PropertyValue as ${__V(__P(Content)_${CounterNum})}
above variable is not fetching value.
Got stuck on how to use __V for this case as it has property variable.
can someone explain me how to use __V when we have property variable.
You don't need __V() function here, you can access property value using __P() function directly like:
${__P(Content_${CounterNum},)}
Demo:
In case of malfunction double check that you're really setting the properties values using Debug Sampler and View Results Tree listener combination
you need to use this
${__V(MainVriableName_${CounterNo})}
1) Add Loop Controller
2) Under Loop Counter -> Add Counter (Starting value= 1, Increment = 1, Maximun value = ${MainVriableName_matchNr} and Exported Variable Name = CounterNo
3) After in the below Request(s) use ${__V(MainVriableName_${CounterNo})}
this works fine.

I would like to read values from a select query and use the values sequentially in a API call.
Since the database values get stored as var_1, var_2 ... var_N
So how do i increment the number for the variable?
I used a counter and pre processor to increment the number in variable
vars.put ("email", "email"+"_"+vars.get("counter"))
But the final variable is not getting replaced by the value from the select query
eg select query result from a debug sampler
email_1=hata.pd.h13u#yopmail.com
email_2=hata.pd.h13u#yopmail.com
email_3=hataiot.test13#mailinator.com
email_4=hataiot.test12#mailinator.com
--combining the variable and counter:
vars.put ("email", "email"+"_"+vars.get("counter"))
--using the variable in the API post body
{
"username":"${email}",
"password":"test1234"
}
Actual result:
POST data:
{
"username":"email_1",
"password":"test1234"
}
Expected result:
{
"username":"hata.pd.h13u#yopmail.com",
"password":"test1234"
}
TIA
${__V(email_${counter})}
Try this one, see also the documentation: http://jmeter.apache.org/usermanual/functions.html#what_can_do
Note that variables cannot currently be nested; i.e. ${Var${N}} does not work. The __V (variable) function can be used to do this: ${__V(Var${N})}. You can also use ${__BeanShell(vars.get("Var${N}")}.
Have you considered using ForEach Controller? It's super-handy for iterating the variables from extractors or JDBC test elements.
If you still want to continue with the current approach you need to change this line:
vars.put ("email", "email"+"_"+vars.get("counter"))
to this one:
vars.put ("email", vars.get("email"+"_"+vars.get("counter")))
Because you're putting into email variable stuff like email_1, email_2, etc. instead of actual ${email_1} variable value.

How to Retrieve Database Data for API Testing with JMeter
EX.hitList values=233,234 Stored in Id_1=233 and id_2=234.I want use this two values one after one.
Use ForEach Controller, Set Input variable prefix = Id and Output variable = currentId
and then inside ForEach Controller you will able to use the variable: ${currentId} in 2 iterations
I have situation where name and value pair are dynamic,
I did two correlations for name and Value separately.
I have used foreach controller and gave input-value as reference name of "Value" regularexpression. which is executing the loop correctly as the match number of Value.
ForEach controller input index is "Cor_OutputValue" and output index is "Cor_OutputValue1".
Problem is how do i change the "Name" for each request .

ForEach Controller save index of loop in a special variable you can use:
JMeter will expose the looping index as a variable named jm__idx. So for example, if your Loop Controller is named FEC, then you can access the looping index through ${__jm__FEC__idx}. Index starts at 0
So in case of your controller name is ForEach Controller to get corresponding value of Value variable use __V function:
${__V(Value_${__jm__ForEach Controller__idx})}
If your values start with index 1 you can increment different variable,as idx inside JSR223 PreProcessor:
vars.put("idx", String.valueOf(Integer.parseInt(vars.get("__jm__ForEach Controller__idx"))+1));
And use it later
${__V(Value_${idx})}
If I set the put key value to the dynamic i value in the graph (this is a requirement),
When I get vars.get("i"), I can only get the value aaa2 when i=2
I want to get all the values(aaa1 and aaa2), what should I do?
To view multiple values you need to save multiple variables by changing your vars.put line to:
vars.put("i" + i, a);
and then get it using ${i[number]} as:
${i0} ${i1} ${i2}
Another option is to concatenate values to variable ${i] similar to
vars.put("i" , (vars.get("i") == null ? "" : vars.get("i")) + a);
Also change your Beanshell sampler to JSR223 Sampler according to JMeter Best Practices
we advise switching from BeanShell to JSR223 Test Elements
In JMeter I added the configuration for oracle server. Then I added a JDBC request object and put the ResultSet variable name to status.
The test executes fine and result is displayed in treeview listener.
I want to use the variable status and compare it with string but jmeter is throwing error about casting arraylist to string.
How to retrieve this variable and compare with string in While Controller?
Just used some time to figure this out and think the accepted answer is slightly incorrect as the JDBC request sampler has two types of result variables.
The ones you specify in the Variable names box map to individual columns returned by your query and these you can access by saying columnVariable_{index}.
The one you specify in the Result variable name contains the entire result set and in practice this is a list of maps to values. The above syntax will obviously not work in this case.
The ResultSet variable returned with JDBC request in JMeter are in the for of array. So if you want to use variable status, you will have to use it with index. If you want to use the first(or only) record user status_1. So you need to use it like status_{index}.
String host = vars.getObject("status").get(0).get("option_value");
print(host);
log.info("----- " + host);
Form complete infromation read the "yellow box" in this link:
http://jmeter.apache.org/usermanual/component_reference.html#JDBC_Request
Other util example:
http://jmeter.apache.org/usermanual/build-db-test-plan.html
You can use Beanshell/Groovy (same code works) in JSR233 PostProcessor to work with “Result Variable Name” from JDBC Request like this:
ArrayList results = vars.getObject("status");
for (HashMap row: results){
Iterator it = row.entrySet().iterator();
while (it.hasNext()){
Map.Entry pair = (Map.Entry)it.next();
log.info(pair.getKey() + "=" + pair.getValue());
}
}
Instead of output to log replace with adding to string with delimiters of your choice.
