I use jmeter data set config to read data from csv file. But I want to convert int to these values. For example in csv data set config there are 1,2,3,4,5. I use as ${variable}+1 or 2*${variable}%10
You can add a JSR223 PreProcessor before the HTTP Request and do some operations there to modify the values:
int newValue = vars.get("variable").toInteger() + 1; OR
int newValue = ${variable} + 1; AND THEN
vars.put("variable", newValue);

I want to test a Get Request with list of values. I dont want to use CSV ,
so i started using Beanshell Preprocessor and has those values in Array. Then used for loop to use those values and send to Get Request in HTTP Request. Every this was Successful except sending values to Get request. It is reading all values and sending the last read value to Get request.
Question : I want my request to run for each value when code reads the data one by one.
var TtValuedetails;
int i;
n=22;
String[] ttvalue = {"34324324224","fdadsfadsf","dfdsfdsfds","dafadsfa",
"45435435","dfadsfads"
};
for(int i=0;i<n;i++)
{
if(i==0)
{
TtValuedetails=ttvalue[i];
if(ttvalue[0]=="34324324224")
{
vars.put("TtValuedetails",TtValuedetails);
log.info(TtValuedetails);
log.info("first value is executed" );
Org.Apache.......startRequest();
}
}
} ;
We cannot help you without seeing the full code and knowing what you're trying to achieve but one thing is obvious: you should not be using Beanshell, since JMeter 3.1 it's recommended to use Groovy for scripting.
Current problem with your code is:
ttvalue array contains 6 elements
n=22
the line TtValuedetails=ttvalue[i]; will cause failure on 7th iteration of the loop due to IndexOutOfBoundsException
If you want to send a request for each value of the ttvalue array the easiest is converting it into separate JMeter Variables like:
ttvalue_1=34324324224
ttvalue_2=fdadsfadsf
etc.
and using ForEach Controller for iterating the values.
Example Groovy code for storing the values into JMeter Variables:
String[] ttvalue = ["34324324224", "fdadsfadsf", "dfdsfdsfds", "dafadsfa",
"45435435", "dfadsfads"];
for (int i = 1; i <= ttvalue.size(); i++) {
vars.put("ttvalue_" + i, ttvalue[i - 1]);
}
I am storing output of JDBC request in Jmeter Variable - "temp_num".
Now I need to concatenate all the values stored in this variable in form of 'a','b','c'......'n'. I did try aggregation withing SLQ script too, but there we have a limit on string length, that's why I would like to probably use something like string builder, but not sure how to use it.
You can convert JDBC result set into a string using JSR223 PostProcessor and the code like :
temp_num = vars.getObject("temp_num");
result = new StringBuilder();
for (Object row : temp_num) {
iter = row.entrySet().iterator();
while (iter.hasNext()) {
pair = iter.next();
result.append(pair.getValue());
result.append(",");
}
}
vars.put('result', result.toString())
However be aware that there is a limit of the number of characters in Java String so make sure not to exceed it.

I need to dynamically generate an XML or JSON in an iteration where the XML or JSON has a variable number of elements -- e.g., it could be books. The values of the books come from the CSV file.
I created a CSV Data Config that point to the CSV file with a variable called csvBook.
Next, in a BeanShell Sampler, I call
StringBuffer sb = new StringBuffer("<Order><Books>");
Random rv = new Random();
int size = rv.nextInt(100);
for (int i = 0; i < size; i++) {
sb.append("<Book Name=" + vars.get("csvBook") + "/>");
}
sb.append("</Books></Order>");
The problem is I don't know how to get new values from the CSV file as I run through the loop inside one iteration. The vars.get("csvBook") returns the same value in the same iteration.
Is there a command to tell JMeter to get the next CSV value (next row) (again, inside one iteration)?
Thanks in advance.
Consider switching to JSR223 Sampler and Groovy language as:
Groovy has built-in support for JSON
Groovy has built-in support for XML
Groovy performance is much better than Beanshell
The relevant Groovy code would be something like:
import groovy.xml.StreamingMarkupBuilder
def csvFile = new File('/path/to/csv/file')
def payload = {
order {
books {
csvFile.readLines().each {line ->
book (name:line)
}
}
}
}
def xmlFile = new File('/path/to/xml/file')
def writer = xmlFile.newWriter()
def builder = new StreamingMarkupBuilder()
def writable = builder.bind payload
writable.writeTo(writer)
I have a Jmeter test in which I want to post an XML message to a JMS queue. This message will be formed dynamically via a BeanShell Preprocessor, which pulls data from multiple CSV Data Set Config elements.
One item of this XML message that is dynamic is the number of elements in it - it will be a random number between 1 and 10. For each Line element, I want to pull a different variable from a CSV Data Set Config element. However, I'm finding if I do something like the below, I keep getting the same variable:
for (int i = 0; i < numberOfLines; i++) {
InputXML = InputXML + "<OrderLine ItemID=\"${ItemID}\" />";
}
The above will keep using the same ${ItemID} variable for all of lines but what I want is for it to grab the next one in the CSV file.
Is there any way to accomplish this via Beanshell?
To go along with your data, if CSV looks like (first row will saved as variables)
0,1,2,3,4,5,6,7,8,9
a,b,c,d,e,f,g,h,i,j
The Beanshell will use index i to get value of column i in CSV:
String InputXML = "";
for (int i = 0; i < 10; i++) {
String a = vars.get(String.valueOf(i));
InputXML = InputXML + "<OrderLine ItemID=\"" + a + "\" />";
}
vars.put("InputXML",InputXML);
InputXML variable will hold the full value.
If you want random value until 10, you can use JMeter function ${__Random(0,10,myRandom)}.
If you want to get random line in CSV you can use the similar answer.
In Jmeter bean shell preprocess is there any way to read the lines of CSV data file and put into an array
csv file contains
data1
date2
date2
i want put all three values in to array and send to Http request in jmeter for for each controller
Thanks in Advance
If you want the Beanshell
BufferedReader reader = new BufferedReader(new FileReader("path.to.your.file.csv"));
int counter = 1;
for(String line; (line = reader.readLine()) != null; ) {
vars.put("date" + counter, line);
counter++;
}
However I don't see any value added by Beanshell here, it is recommended to avoid scripting and use JMeter components where possible. If you need to send values from CSV file consecutively I would recommend using one of the following test elements instead:
CSV Data Set Config
CSVRead or StringFromFile functions
