Jmeter- How to load test a upload file inside a login session?

Question

Scenario to test:

step 1: Login with username and password step 2:go to upload page step 3:select a file and click upload(POST request)- Need to do load testing on this POST request.

My setup in JMeter- login and go the the upload page is set with for example 10 threads in 5 ramp up time.

Then,I have tried with synchronization timer under the upload POST request. So, now what happens is 10 logins happens in 5 seconds and after that the 10 upload POST request is send at the same time.

What I need is,

Since I do not want to test the load of login, I do not want to make these 10 logins requests to be send to server. And I cannot pass the session ID in upload POST request since our system is having so much of authentication of a user with uuid and JWT token. Is there a possible way to do this much simpler?

Jmeter Version is 3.2

Answer 1

If you won't be logged in my expectation is that the upload request will fail. You might come up with the relevant Thread Group configuration like define ramp-up period higher than response time so you will not have any concurrency on login.

Later on you can use Filter Results tool in order to exclude "not interesting" requests from the .jtl results file.

Filter Results Tool can be installed using JMeter Plugins Manager

You might also need Merge Results tool as well.
