Benchmarking Solr indexing with Jmeter - http

Question

I want to use Jmeter to update a document on solr using http post.
I want it to take a different file to update in every iteration, create a proper http post request and monitor the responses from the server.
Can someone guide me of how this can be done:
Taking a different file every time.
Creating a http post from it.

Answer 1

Your use case can be split into 2 parts:
Get list of files to send
Send them to server
In regards to point 1, I would suggest to obtain file list via scripting.
Assuming following Test Plan Structure:
Add a Thread Group (all defaults)
Add a JSR223 Sampler as a child of Thread Group
Select "beanshell" as language
In "Script" area add following code:
File folder = new File("PATH TO FOLDER WITH YOUR FILES");
File [] files2send = folder.listFiles();
int counter = 1;
for (File file : files2send)
{
vars.put("FILE_" + counter, file.getPath());
counter++;
}
This will save files, you will be sending as JMeter Variables like:
FILE_1=d:\2solr\sometxtfile.txt
FILE_2=d:\2solr\somewordfile.docx
FILE_3=d:\2solr\someexcelfile.xlsx
After that you can use For Each Controller to iterate through files and add them to your request
Add For Each Controller as a child of Thread Group (same level as JSR223 Sampler)
Make sure that For Each Controller has following configuration:
Input variable prefix: FILE
Output variable name: CURRENTFILE
Add _ before number is checked
Add HTTP Request as a child of For Each Controller
Access file you want to send as ${CURRENTFILE} in "Send Files With The Request" stanza of the HTTP Request
It's just one of the approaches, if you are not very comfortable with JSR233 or Beanshell you may wish to use CSV Data Set Config instead.
