Do not change your test design because the design is difficult to implement in your tool. If you cannot implement your test as designed, ensure that you record the details pertaining to the test that you do implement. Ensure that the model contains all of the supplementary data needed to create the actual test. Consider including invalid data in your performance tests. For example, include some users who mistype their password on the first attempt but get it correct on a second try. First-time users usually spend significantly more time on each page or activity than experienced users. The best possible test data is test data collected from a production database or log file. Think about nonhuman system users and batch processes as well as end users. For example, there might be a batch process that runs to update the status of orders while users are performing activities on the site. In this situation, you would need to account for those processes because they might be consuming resources. Do not get overly caught up in striving for perfection, and do not fall into the trap of oversimplification. In general, it is a good idea to start executing tests when you have a reasonable test designed and then enhance the design incrementally while collecting results.
