I want to use 100 concurrent users in one thread group in Jmeter. but I want to each thread to use different user login password. how to achieve that?
full credit to Apache Jmeter documentation:
Some test plans need to use different values for different users/threads. For example, you might want to test a sequence that requires a unique login for each user. This is easy to achieve with the facilities provided by JMeter.
For example:
Create a text file containing the user names and passwords, separated by commas. Put this in the same directory as your test plan. Add a CSV DataSet configuration element to the test plan. Name the variables USER and PASS. Replace the login name with ${USER} and the password with ${PASS} on the appropriate samplers The CSV Data Set element will read a new line for each thread.
