Is it possible to pass in file path or read from another file within csv? My test setup is something like that.
Jmeter Test
Http request -> body data -> "items": "${__property(${items})}",
CSV data config
Id,Name,Items
1,MyName,\input\items_json.txt
I want to include a file in csv items column and in jmeter test, it will read and post items json.
Got it working with this.
"items": ${__FileToString(${__property(${Items})},,)},
Not really, being a Configuration Element CSV Date Set Config is initialised before anything else so you will have to consider another approach, i.e.:
__CSVRead() function
__StringFromFile() function
__FileToString() function()
Functions are being evaluated exactly where they're called so this way you can use them for parameterization. See Apache JMeter Functions - An Introduction to learn more about JMeter Functions concept

In my JMeter test plan, I have two CSV Data Config elements.
CSV Data Config-element-requestBodies: This CSV Data Config element has a variable named "requestBody". In the corresponding CSV file, each line has an XML request with a placeholder string.
CSV Data Config-element-subject: variables. This CSV Data Config element has a variable name "subjectDn". In the corresponding CSV file, each line has a distinguished name (DN) for a user.
The "requestBody" variable will contain an XML request from the CSV file that has the request bodies, with a placeholder string and I want to replace that placeholder with the contents of the "subjectDn" variable, and then use the modified "requestBody" variable in the HTTP Request element.
In other words:
Replace the placeholder string in the ${requestBody} with the value in the ${subjectDn}, then
Use the modified ${requestBody} in the HTTP Request
How can I do that? What is the easiest/least overhead way of doing that?
I've tried using the "__evalVar" function (see https://am.net/lib/tools/NetworkManagement/apache-jmeter-2.8/printable_docs/usermanual/functions.html), but it looks like that is not able to do the replacement when the string is from a CSV file?
Thanks in advance!

Wrap your ${requestBody} into __eval() function, it will allow JMeter to resolve JMeter Functions and Variables which are present as "placeholders" in the CSV file to their respective values.
${__eval(${requestBody})}
Also if you consider scripting to accomplish your requirements be informed that starting from JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language. More information: Apache Groovy: What Is Groovy Used For?
I was able to get this woring by using a Beanshell pre-processor and some Java code that does var.get() and then Java String replaceall() and then var.put().
I have a SOAP request. I need to use jmeter to test multiple requests for same method, each time passing one missing element.
How can I achieve this ?
I tried writing the tags into csv using CSV data config , but I am unable to enter empty values in the csv, each time for a different tag in each csv row.
Any help would be appreciated. Thank you.
The CSV Data Set Config will read the value from next line only on the next iteration of the thread (virtual user), you cannot read more than one line within the bounds of a single iteration. You might want to take a look at __CSVRead() function where it's you who decides when to proceed to the next line.
If the __CSVRead() function isn't applicable for your use case be aware that you can build a request body, i.e. XML from CSV file using JSR223 PreProcessor and Groovy language.
See Creating XML chapter of Groovy documentation for more details.
How to pick json playload from external file in jmeter?
I Want to login with multiple users for that I need to add Json request. I need to pick json parameter/Json request from external file. Please let me know the process so that i can pick json parameter from external file.
Json request for example
{"username":"honey#est.com","password":"Phone#123","provider":"","access_token":""}
If you want to read a single line from a file - go for CSV Data Set Config or __StringFromFile() function
If you want to read entire file - go for __FileToString() function
If you have a folder with multiple JSON files and would like to iterate all of them - check out Directory Listing Config
It's also possible to read a file using JMeter's HTTP Request sampler
this way you will be able to use Post-Processors to extract partial data if needed.
I am using Jmeter for load testing. I am passing parameters of the body from a csv file for an api. But our application will not receive the duplicate value. So when i load test by multiple users, the request get failed.because i am passing same parameter value for all users.So i need to make some of the columns with an instant value(random). so that different users will get different values.
{
"clinic_name":"clicnic",
"first_name":"provider1",
"initial":"v",
"last_name":"doc",
"salutation":"salu",
"address_1":"testttadd1",
"address_2":"testtttadd2",
"city":"ckdy",
"state":"Arizona",
"zip":"12365",
"fax":"",
"email":[{"email_id":"dfdf#dzcz.in","type":"Work","note":null}],
"phone":[{"number":"1235974444","note":"","type":"Mobile","extension":""}]
}
here i have given the request body and i need different email for different users. How can i do this?Can anyone help me..Thanks in advance.
you can use __RandomString function for the value of email_id:
"${__RandomString(15, abcdefghijklmnopqrstuvwxyz)}#${__RandomString(10, abcdefghijklmnopqrstuvwxyz)}.in"
The easiest is using Faker library like:
Download Java Faker jar and drop it to JMeter Classpath
Restart JMeter to pick the .jar up
You can use the following __groovy() function directly in the HTTP Request sampler body:
${__groovy(new com.github.javafaker.Faker().internet().emailAddress())}
Alternatively you can put the above expression into your CSV file, however make sure to wrap the variable reference into __eval() function, for example if you had ${email} you will need to change it to ${__eval(${email})}
CSV Data Config from JMeter contains following -
File.csv Contains following
GetAllOrderItems.txt contains following
{"dataRows":[],"orderGuid":"${orderGuid_1_g1}","facilityPk":"0","jtStartIndex":0,"jtPageSize":100,"jtSorting":"SKU ASC","isMap":"1"}
orderGuid_1_g1 is fetched from Regular Expression extractor
I passed following to JMeter body data
When I execute JMeter test, I can see follwing
{"dataRows":[],"orderGuid":"${orderGuid_1_g1}","facilityPk":"0","jtStartIndex":0,"jtPageSize":100,"jtSorting":"SKU ASC","isMap":"1"}
However, I want ${orderGuid_1_g1} to be fetched from Reg Ex of previous HTTP Request.
I want following
{"dataRows":[],"orderGuid":"644e1dd7-2a7f-18fb-b8ed-ed78c3f92c2b","facilityPk":"0","jtStartIndex":0,"jtPageSize":100,"jtSorting":"SKU ASC","isMap":"1"}
Code works well, If i did not fetch Body data from text and directly insert below code inside body of HTTP Request
{"dataRows":[],"orderGuid":"${orderGuid_1_g1}","facilityPk":"0","jtStartIndex":0,"jtPageSize":100,"jtSorting":"SKU ASC","isMap":"1"}
If your file contains nested JMeter Variables you need to wrap your __FileToString() function call in __eval() function like:
${__eval(${__FileToString(${GetAllOrderItems})})}
Demo:
More information: Here’s What to Do to Combine Multiple JMeter Variables
JMeter does not interpret variables when you load content from a file.
Besides, for a load test using __FileToString function is not advised unless it is used for setup for example which is not the case here.
So just put the JSON Body request in the request body, it will be better for readability.
