Performance tests often require the use of test data for user accounts, data input, and data validation. VPT supports using test data with your performance tests. If your script requires test data, then upload the test data file alongside your test script. All you need to do is make sure that your test data file is selected when configuring your test, and it will be sent to all the load generators used for your test.
NOTE: VPT currently only supports test data files in CSV format and will split the file by line as evenly as possibly between all the load generators used for a test.
