We have few load runner scripts that take XML file as input and reads these xml files for data.
For example:
while (!feof(file_ptr))
{
/* Check for file I/O errors */
if (ferror(file_ptr))
{
lr_output_message("Error reading file %s", filename);
break;
}
}
Please let me know if we can handle these file handling operations (other than CSV file) in jmeter
You can use __FileToString function to read an arbitrary file into a JMeter Variable which can later be used anywhere in the current thread group.
Refer to How to Use JMeter Functions post series for extra information on this and other various helpful JMeter functions.
You can use BeanShell Sampler for reading the XML file.
You can write a code in BeanShell sampler to read the xml file which you can write in JAVA.
And you can store the xml contents in Object type you want i.e Hashtable, ArrayList etc...

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.
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
i have one requirement, it might be simple but not getting any clue. Actually in my jmeter script i am getting one http response as csv file. The same file i need to read into my post processor script which is groovy script. Any one has any idea how to do this, struggling from past couple of days but not getting any clue.
If I correctly got your use case, you have:
HTTP Sampler which is hitting some CSV file
Some Post Processor in which you want to read data from this CSV file
If you look into View Results Tree listener into your request, which retrieves CSV file you should see this CSV file contents.
JMeter provides powerful BeanShell Post Processor which is capable of interacting with JMeter Context. It's as simple as next line:
vars.put("myCSV",prev.getResponseDataAsString());
Another option is to store response data as a new CSV file as follows:
FileOutputStream out = new FileOutputStream("my.csv");
out.write(prev.getResponseData());
out.flush();
out.close();
As the result of above you'll store your response as file "my.csv" in the folder, from where you launched JMeter (usually /bin folder of your JMeter installation).
After that you will be able to use "my.csv" file in CSV Data Set Config to iterate through the variables as usual.
