Reading CSV Data File sequentially
Hi,
I am new to JMeter and trying to execute a load test on the application.
here is the scenario I want to test for 100 concurrent users.
1. Thread group having 100 threads.
- Login with a username/password. I have specified a CSV data file which
has comma seperated username and password for each user.
- another sampler which edits something which is posted by the logged in
user. This sampler also has a CSV data file which has data the user will
edit.
now the condition is to execute 2nd sampler is user who is currently logged
in should be the owner of the post. If not the request will fail. The order
of the two CSV data config files is same means.
I am trying to ramp up 100 threads in 10 seconds and the login is
successfull but What I observed is Jmeter is not loging the users in the
same sequence as mentioned in the file. because of this the second sampler
is failing.
If I increase the ramp up time to 100 seconds then it does login them
sequentially but then I wont be able to simulate the case of 100 concurrent
users.
Please suggest me how to achieve this in JMEter.
Your help is greatly appreciated.
Regards,
Ashish

Thanks a lot for your reply.
It works now. I dont even have to specify user variables. I am reading the
CSV Data file only once and just mentioning the variables where required.

Not sure what you mean. The variables set by CSV Dataset are set in
the thread; once set, any test element in the thread can access them.

If "title" and "description" (without ") are the names you provided on
the CSV Dataset element, then you can refer to ${title} and
${description} anywhere you want their values.

Please read up about the CSV Dataset and Debug sampler and play with
some test plans.

Re: Reading CSV Data File sequentially
Posted by AshishJJ <as...@gmail.com>.
Thanks for the reply.
I still have one question.
Can I specify the CSV Data Set config only once for the login controller and
store the values of the variables other than usename, password read in a
user variables and supply them when the other controller is run?
If yes how to do it? For example:
name=uservariable1 value=${title}
name=uservariable2 value=${description}
where ${title} and ${description} are 2 values read from CSV Data set
config?
Please suggest.

CSV Dataset will store the line, split into the variables that you specify.
Variables retain their value until they are updated, e.g. when the
next loop of the containing controller runs the CSV Dataset again.
I assume you must have been doing this already for the login process to work ...
Use the Debug Sampler + Tree View Listener to see what variables are set.

Re: Reading CSV Data File sequentially

Is there anything in JMeter which will allow me to read the combined data
from one file and store the data for the post to be used when that request
gets executed?
