Develop Test Data
During this activity, the performance tester works closely with application subject matter experts and database administrators to determine, collect and/or create test data to represent real users. Some applications require little more than a random number generator while other applications require significant data analysis due to data dependency of tasks to be modeled. It is safer to assume this will be a complex task until proven otherwise. The performance tester may be significantly involved in creating test data, or just involved in identifying test data to be created depending on the context of the project.
