You can produce more realistic tests by modifying them to use datapools. During execution, a test that uses a datapool replaces a value in the recorded test with variable test data stored in the datapool. This substitution allows each virtual user to generate a different request to the server.
Datapool overview
Datapools provide your tests with variable data when they run.Enabling a test to use a datapool
A test must contain a reference to any datapool that it uses.Associating a value in a test with a datapool column
To cause your test to use variable data instead of a specific value, you associate values in the test with columns in a datapool.
